(Embodiment 1)
FIG. 1 is a diagram showing a configuration example of the communication device 1 of the present embodiment. In FIG. 1, only the functional blocks related to the present embodiment are extracted and shown. The communication device 1 includes a main signal processing unit 2, a response unit 3, a setting unit 4, and a switching unit 5. Note that FIG. 1 shows a configuration in which the communication device 1 includes both the response unit 3 and the setting unit 4, but the communication device 1 is configured to include either the response unit 3 or the setting unit 4. May be done. The main signal processing unit 2 processes a main signal input from UNI (User Network Interface), SNI (Application Server Network Interface), NNI (Network Network Interface), or the like. The response unit 3 responds to a response request from an external device such as an ONU, a switch, or a controller. The setting unit 4 sets, changes the setting, and deletes the main signal processing unit 2 and other components. The switching unit 5 switches the response unit 3 or the setting unit 4 to a new response unit 3 or the setting unit 4. The parts in this embodiment are software parts such as FASA (Flexible Access System Architecture) applications, which will be described later, external parts, and the like. A FASA application is a software component that realizes, for example, a function different for each service or each telecommunications carrier by using a general-purpose input / output interface (for example, FASA application API).

The setting, setting change, setting deletion, and response request to the response unit 3 or the setting unit 4 may be via the main signal processing unit 2, or may be via another control network or the like. The main signal processing unit 2, the response unit 3, and the setting unit 4 may be FASA applications. Further, the main signal processing unit 2 may be a FASA platform described later. Note that FIG. 1 is a configuration in which a plurality of functions (for example, a setting, a setting change, a setting deletion function, and a response function) are switched and used.

The surface may be switched internally in preparation for each of the setting unit and the response unit, or at least one of the setting unit and the response unit on a plurality of surfaces is connected to the main signal processing unit 2, and the setting unit on a certain surface is connected. And at least one of the response units may be active and the rest may not be active, or at least one of the multi-sided setting unit and the response unit may be connected via a switching unit to respond to the setting unit on a certain surface. The switching unit may connect at least one of the units.
Instead of switching faces, one of a plurality of parts may be put into an operating state, a request and a response may be exchanged with one of the plurality of parts, a part may be overwritten, or a part may be replaced. May be good.

FIG. 2 is a diagram showing an example of a case where application files are exchanged and executed. As shown in FIG. 2, the communication device 1 holds a function, for example, an application downloaded from a server or the like in a file system inside the communication device 1, overwrites an old application file with a new application file, and executes the application. Here, although illustrated by overwriting, the communication device 1 may replace the old application file with the new application file, switch the surface, activate any of the coexisting files, or coexist. You may exchange settings or requests and responses with either.

Replace application files using the following procedure.
1. 1. Application download:
The FASA application file is transferred or transferred from the server to the communication device 1 by FTP / TFTP (File Transfer Protocol / Trivial File Transfer Protocol), and the communication device 1 installs, makes, or builds the FASA application file. If the transfer and the installation or make or build are separate procedures, the communication device 1 may separately provide the installation, make or build procedure. When transferring or installing, the corresponding parts may be overwritten or replaced, may be on the switching surface without overwriting or replacing, or may coexist so that either one can be activated. , Either set or request and response may coexist so that they can be exchanged.

2. 2. Add application:
The communication device 1 executes the FASA application that has been downloaded, installed, made, or built. The communication device 1 may put the FASA application into the execution state at a preset designated time.
3. 3. Application replacement:
The communication device 1 terminates the running FASA application and executes applications of different versions. The communication device 1 may execute a different FASA application, for example, a different version or a different function, at a preset designated time. Further, when the communication device 1 has a plurality of functions, at least one of the input and the output may be discarded without terminating the FASA application. When overwriting, steps 1 to 3 above may be performed at the same time. One of the coexisting may be active, or the setting or request and response may be exchanged with the coexisting one.

4. Application stop:
The communication device 1 stops the running FASA application.
5. Application removal:
The communication device 1 deletes the FASA application (and related) files from its own device, or uninstalls and deletes the files. 4 to 5 of the above procedure may be simultaneous.
6. Application status display:
The communication device 1 displays at least one of the type, function, version number, execution status, and the like of the FASA application.

7. Logging:
The communication device 1 records a log of addition / replacement / deletion of the FASA application and creates a file.
8. Capacity display:
The communication device 1 displays the used capacity and the free capacity of the area in the own device for storing the FASA application. The area to be stored or used may include a device outside the own device or other devices constituting the device of one sentence.

When switching the response unit 3 or the setting unit 4, the communication device 1 performs one of the following operations.
(1) The switching unit 5 discards the setting request, the deletion request, the change request, or the response request when the response unit 3 or the setting unit 4 is switched. Specifically, the communication device 1 may be passed to the FASA application or the function in the FASA platform to be discarded when there is no switching or response, or the processing by the FASA application or the function in the FASA platform in the FASA platform. It may be discarded by the function of handing over. It is suitable when the setting request, deletion request, change request, or response request is discarded and then retransmitted, or when there is a time limit until the processing is completed.

(2) The switching unit 5 holds a setting request or a deletion request or a change request or a response request when the response unit 3 or the setting unit 4 is switched, and the response unit 3 or the setting after changing the held request. Input to part 4. Specifically, when there is no switching or response, the switching unit 5 may pass it to the FASA application or the function in the FASA platform to be held, or the processing in the FASA application or the function in the FASA platform in the FASA platform. It may be held by the function of passing. It is suitable when erroneous processing is not allowed or when there is a margin in the time limit until the processing is completed and it is possible to wait. It is desirable that the switching unit 5 discards a request that is no longer needed due to a predetermined time elapsed after holding the request, resending the request due to a timeout or the like, or changing the situation. The changing situation is, for example, a setting item that is present before the replacement but not after the replacement.

(3) The communication device 1 includes a proxy function unit that processes a setting request, a deletion request, a change request, or a response request when the response unit 3 or the setting unit 4 is switched, and the response unit 3 or the setting unit 4 Instead of, the surrogate function department responds by proxy. Specifically, the communication device 1 may pass to a function in the FASA application or the FASA platform that responds by proxy when there is no switching or response, or in the FASA application or the function in the FASA platform within the FASA platform. You may make a proxy response with the function of passing the process. When the performance deteriorates when the processing is delayed, it is suitable for cases where the erroneous processing can be corrected later, for example, when observing low-delay QoS, or band allocation where the error can be corrected by later allocation.

The proxy response may be provided in another device on the main signal, for example, a higher-level switch, if the request flows on the main signal path, or another device on the path if the request flows outside the main signal path. Do. Further, the application may be an application that allows only predetermined settings and responses to be easily switched, may be a platform such as middleware in which the application is arranged, or may be the main signal processing unit 2. At the time of proxy response, it is desirable to provide a functional unit that retains the response history, for example, on a list or database shared by the application after switching and the applications before, during, and after switching.

If the proxy function unit's response is inappropriate, it is desirable to correct it.
The proxy response value may be a predetermined value, a value for requesting retransmission of the request, a value for proceeding with processing such as registration authentication, but not for frame transfer to an erroneous destination, or a safe value. A safe value is a value that does not violate the contract of QoS or SLA in the case of bandwidth allocation such as DBA, for example, a set value of guaranteed bandwidth allocation or a destination of a frame whose destination is undecided from the viewpoint of preventing erroneous delivery. Is the value of the destination that discards the frame, the default destination such as a static route from the viewpoint of preventing transmission omission, and the destination of the function that substitutes the processing such as the open flow controller.

As one form of proxy response, if bandwidth is allocated by BWMap or the like, a table of BWMap with safe values to be used orbiting is prepared, and if the BWMap value arrives at the FASA infrastructure or the actual processing status from the FASA application or the like. Overwrite and output with safe value if it does not arrive. In this proxy response method, a proxy response for non-delivery of BWMap to the FASA platform or the actual processing is automatically possible. BWMap is generated based on the BWMap entry prepared in advance or the calculation prepared in advance when the BWMap is not delivered by a predetermined time before the BWMap issuance time of the FASA platform or the actual processing. The predetermined time is longer than the time required for BWMap entry and BWMap generation prepared in advance. When switching of the FASA application or the like or communication interruption with the FASA application or the like is detected, BWMap is generated based on the BWMap entry prepared in advance or the calculation prepared in advance.

In the communication device 1 of the present embodiment, the internal function is divided into a main signal processing unit 2, a response unit 3, a setting unit 4, and a switching unit 5, and only the response unit 3 or the setting unit 4 is switched. .. As a result, even if the response unit 3 or the setting unit 4 is switched, the processing of the main signal performed by the main signal processing unit 2 is not affected. Therefore, it is possible to replace the FASA application without interruption of service while keeping the main signal conductive. As a result, the communication device 1 can be virtualized. Hereinafter, a plurality of operation examples of the switching process of the communication device 1 will be described as an example. In the following operation example, a case where the response unit 3 or the setting unit 4 to be switched is a FASA application will be described as an example.

(First operation example)
As a first operation example, the communication device 1 includes a list related to processing, calls the FASA application described in the list, and outputs data to the FASA application that called the data. In the first operation example, the communication device 1 holds a list related to processing (hereinafter referred to as “processing list”) as information about parts. In the processing list, the processing content of the data and the FASA application that processes the data are associated with each other. The communication device 1 sequentially calls the FASA application that processes the data based on the input data and the processing list, and outputs the data or the output of the FASA application in the previous order to the called FASA application. Switching corresponds to changing the FASA application to be called. Here, the data to be output may be all the data. In this case, since the group of data is collectively passed to the FASA application, there is an effect that the group of data is not separated and becomes easy to understand.

Further, the communication device 1 may output only the data related to the processing to the FASA application without outputting the data not processed by the FASA application to the FASA application. In this case, there is an effect that the amount of output data can be reduced. In particular, the communication device 1 has an effect that the amount of data to be output can be reduced when the actual data is output to the FASA application instead of the index representing the storage location of the data. It is desirable that a plurality of processes are performed in parallel by pipeline processing or the like.

Further, the processing list may be separately held in the communication device 1 for each parallel processing, or may be shared by a plurality of processings. When separately held, it is easy to record the data distribution status for each processing list, and when shared, it is desirable that the communication device 1 separately holds a record regarding the data distribution status for each processing. Although the output of the actual data has been mainly described here, the communication device 1 outputs information indicating the data storage location (for example, the address of the data storage destination), and the output information of each component is used. Data may be processed on the storage location identified based on it.

In this operation example, if the application to be switched does not call or does not answer the call, the application in the next order is called, or the process that takes time to switch the application is discarded. (1) Setting request or deletion request or change Respond to discard request or response request. Specifically, when there is no switching or response, the next order may be called or discarded to the FASA application or the function in the FASA platform, or the processing in the FASA application or the function in the FASA platform within the FASA platform. The next order may be called or discarded by the function of passing.

Waiting for the call of the application until the switching of the application to be switched is completed, or waiting for the call in the application in the order before the application related to the processing that takes time for the application to switch, or waiting at the beginning or the middle of the processing list is (2) A setting request, a deletion request, a change request, or a response request is held, and the held request is input to the changed response unit 3 or the setting unit 4. Specifically, when there is no switching or response, it may be passed to the FASA application or the function in the FASA platform to be retained, or the function to pass the processing in the FASA application or the function in the FASA platform within the FASA platform. May be retained.

If the switching application does not call or does not answer the call, the call to the proxy response application that outputs a predetermined value corresponds to (3) proxy response.
Specifically, (1) a branch process of switching to another process list in which the application is skipped or skipping the application when switching or not responding. (2) When switching or not responding, the processing request or the intermediate result of processing and the processing itself are accumulated, and when the switching is completed or responded, the processing is started or restarted. (3) When switching or not responding, switch to the processing list that calls the application that responds by proxy, or branch processing so as to jump to the application that responds by proxy. Specifically, when there is no switching or response, it may be passed to the FASA application or the function in the FASA platform that responds by proxy, or the function to pass the processing in the FASA application or the function in the FASA platform within the FASA platform. You may make a proxy response with.

(Second operation example)
As a second operation example, the communication device 1 sequentially calls a plurality of FASA applications associated with the contents of the data according to the contents of the data, and outputs the data or the FASA application in the previous order to the called FASA applications. Output. In the second operation example, the communication device 1 holds a list (hereinafter referred to as "processing chain list") showing the parts to be processed in the order in which the processing is performed as the information about the parts. In the processing chain list, the processing content of the data and the FASA application shown in the order in which the data is processed are associated with each other. The communication device 1 sequentially calls the FASA application that processes the data based on the input data and the processing chain list, and outputs the data or the output of the FASA application in the previous order to the called FASA application.

Specifically, the communication device 1 first refers to the processing chain list and identifies the FASA application that first processes the input data. Next, the communication device 1 calls the specified FASA application and outputs data to the called FASA application. When the processing of the data by the called FASA application is completed, the communication device 1 refers to the processing chain list and identifies the FASA application that processes the data next. Next, the communication device 1 calls the specified FASA application, and outputs data or the output of the FASA application in the previous order to the called FASA application. After that, the communication device 1 repeats the call of the FASA application and the output of the data or the output of the FASA application in the previous order according to the processing chain list until the processing for the input data is completed. Switching corresponds to changing the FASA application on the list.

Here, the data to be output may be all the input data. In this case, since the group of data is collectively passed to the FASA application, there is an effect that the group of data is not separated and becomes easy to understand. Further, the communication device 1 may output only the data related to the processing to the FASA application without outputting the data not processed by the FASA application to the FASA application. In this case, there is an effect that the amount of output data can be reduced. In particular, the communication device 1 has an effect that the amount of data to be output can be reduced when the actual data is output to the FASA application instead of the index representing the storage location of the data. It is desirable that a plurality of processes are performed in parallel by pipeline processing or the like.

Further, the processing chain list may be separately held in the communication device 1 for each parallel processing, or may be shared by a plurality of processings. When separately held, it is easy to record the data distribution status for each processing chain list, and when shared, it is desirable that the communication device 1 separately holds a record regarding the data distribution status for each processing. Although the output of the actual data has been mainly described here, the communication device 1 outputs information indicating the data storage location (for example, the address of the data storage destination), and the information output by each FASA application. Data may be processed on the storage location specified based on.

In this operation example, if the application to be switched does not call or does not answer the call, the application in the next order is called, or the process that takes time to switch the application is discarded. (1) Setting request or deletion request or change Respond to discard request or response request. Specifically, if there is no switching or response, it may be passed to the FASA application or the function in the FASA platform to be discarded, or it may be discarded by the function to pass the processing in the FASA application or the function in the FASA platform in the FASA platform. You may.

Specifically, when there is no switching or response, it may be passed to the FASA application or the function in the FASA platform to be retained, or the function to pass the processing in the FASA application or the function in the FASA platform within the FASA platform. May be retained.

If the switching application does not call or does not answer the call, the call to the proxy response application that outputs a predetermined value corresponds to (3) proxy response.
Specifically, (1) A branch process of switching to another processing chain list that skips the application or skipping the application when switching or not responding. (2) When switching or not responding, the processing request or the intermediate result of processing and the processing itself are accumulated, and when the switching is completed or responded, the processing is started or restarted. (3) Processing that calls the application that responds by proxy when switching or not responding Branch processing to switch to the chain list or jump to the application that responds by proxy. Specifically, when there is no switching or response, it may be passed to the FASA application or the function in the FASA platform that responds by proxy, or the function to pass the processing in the FASA application or the function in the FASA platform within the FASA platform. You may make a proxy response with.

(Third operation example)
As a third operation example, the communication device 1 makes a predetermined correspondence based on at least one of the history of the data output source (for example, the last output source, the penultimate second and the previous) and the data content. The FASA applications specified in the table are sequentially called, and the data or the output of the FASA application in the previous order is output to the called FASA application. Here, the output source is an external device or an ONU or an OLT internal or a FASA platform or a FASA application. In the third operation example, the communication device 1 holds a correspondence table related to processing as information about the FASA application. In the correspondence table, at least one of the data processing content and the data output source is associated with the FASA application that processes the data. It does not have to be limited to the correspondence table. Switching corresponds to a change in the FASA application described in the correspondence table or the like.

In this case, when the data is input, the communication device 1 refers to the correspondence table and identifies the FASA application associated with the content of the input data. Then, the communication device 1 outputs data or the output of the FASA application in the previous order to the specified FASA application.

(When the data output source, the content of the data, and the FASA application that processes the data are associated with each other in the correspondence table)
In this case, when the data is input, the communication device 1 refers to the correspondence table and identifies the FASA application associated with both the output source of the input data and the content of the data. Then, the communication device 1 outputs data or the output of the FASA application in the previous order to the specified FASA application.

Here, the data to be output may be all the input data. In this case, since the group of data is collectively passed to the FASA application, there is an effect that the group of data is not separated and becomes easy to understand. Further, the communication device 1 may output only the data related to the processing to the FASA application without outputting the data not processed by the FASA application to the FASA application. In this case, there is an effect that the amount of output data can be reduced. In particular, the communication device 1 has an effect that the amount of data to be output can be reduced when the actual data is output to the FASA application instead of the index representing the storage location of the data. It is desirable that a plurality of processes are performed in parallel by pipeline processing or the like.

(3) Call the application that responds by proxy when switching or not responding. Branch processing so as to switch to the correspondence table or jump to the application that responds by proxy. Specifically, when there is no switching or response, it may be passed to the FASA application or the function in the FASA platform that responds by proxy, or the function to pass the processing in the FASA application or the function in the FASA platform within the FASA platform. You may make a proxy response with.

Further, the correspondence table may be separately held in the communication device 1 for each parallel process, or may be shared by a plurality of processes. If it is held separately, it is easy to record the data distribution status for each correspondence table, and if it is shared, it is desirable that the communication device 1 separately holds a record regarding the data distribution status for each process. Although the output of the actual data has been mainly described here, the communication device 1 outputs information indicating the data storage location (for example, the address of the data storage destination), and the information output by each FASA application. Data may be processed on the storage location specified based on.

(Fourth operation example)
As a fourth operation example, the communication device 1 makes a predetermined correspondence based on at least one of the history of the data output source (for example, the last output source, the penultimate second and the previous) and the data content. The FASA applications specified in the table are sequentially called, and the data or the output of the FASA application in the previous order is output to the called FASA application. Here, the data output source is an external device or an ONU or an OLT internal or a FASA platform or a FASA application. In the fourth operation example, the communication device 1 holds a correspondence table related to processing as information about parts. In the correspondence table, at least one of the data processing content and the data output source is associated with the FASA application that processes the data. It does not have to be limited to the correspondence table. Switching corresponds to a change in the FASA application described in the correspondence table or the like.

In this operation example, if the application to be switched does not call or does not answer the call, the application in the next order is called, or the process that takes time to switch the application is discarded. (1) Setting request or deletion request or change Respond to discard request or response request. Specifically, when there is no switching or response, the next order may be called or discarded to the FASA application or the function in the FASA platform, or the processing in the FASA application or the function in the FASA platform within the FASA platform may be passed. The next order may be called or discarded by the function of passing.

Waiting for the call of the application until the switching of the application to be switched is completed, or waiting for the call in the application in the order before the application related to the processing that takes time for the application to switch, or waiting at the beginning or the middle of the correspondence table is (2) A setting request, a deletion request, a change request, or a response request is held, and the held request is input to the changed response unit 3 or the setting unit 4.
If the switching application does not call or does not answer the call, the call to the proxy response application that outputs a predetermined value corresponds to (3) proxy response.

Specifically, (1) A branch process of switching to another correspondence table in which the application is skipped or skipping the application when switching or not responding. (2) When switching or not responding, the processing request or the intermediate result of processing and the processing itself are accumulated, and when the switching is completed or responded, the processing is started or restarted. (3) Call the application that responds by proxy when switching or not responding. Branch processing so as to switch to the correspondence table or jump to the application that responds by proxy. Specifically, when there is no switching or response, it may be passed to the FASA application or the function in the FASA platform that responds by proxy, or the function to pass the processing in the FASA application or the function in the FASA platform within the FASA platform. You may make a proxy response with.

Here, the data to be output may be all the input data. In this case, since the group of data is collectively passed to the FASA application, there is an effect that the group of data is not separated and becomes easy to understand. Further, the communication device 1 may output only the data related to the processing to the FASA application without outputting the data not processed by the component to the component. In this case, there is an effect that the amount of output data can be reduced. In particular, the communication device 1 has an effect that the amount of data to be output can be reduced when the actual data is output to the component instead of the index representing the storage location of the data. It is desirable that a plurality of processes are performed in parallel by pipeline processing or the like.

Further, the correspondence table may be separately held in the communication device 1 for each parallel process, or may be shared by a plurality of processes. If it is held separately, it is easy to record the data distribution status for each correspondence table, and if it is shared, it is desirable that the communication device 1 separately holds a record regarding the data distribution status for each process. Further, Forwarding-Engine, SW, or the like may be used to transfer data to the FASA application. The use of Forwarding-Engine, SW, or the like is particularly suitable when the data is in a predetermined frame format. Although the output of the actual data has been mainly described here, the communication device 1 outputs information indicating the data storage location (for example, the address of the data storage destination), and the information output by each FASA application. Data may be processed on the storage location specified based on. As for the destination (storage destination), when the communication device 1 instructs the next FASA application for each process, it takes time to refer to the Table (correspondence table) / list one by one, but it is not necessary to convey the destination information to the parts, which will be described later. TAG also has the effect of becoming unnecessary.

(Fifth operation example)
As a fifth operation example, the communication device 1 specifies the data output destination based on the tag, sequentially calls the specified predetermined parts, and outputs the data to the called FASA application. Here, the data output source is an external device or an ONU or an OLT internal or a FASA platform or a FASA application. In the fifth operation example, the communication device 1 specifies the data output destination based on the tag, sequentially calls the specified predetermined FASA application, and outputs the data or the FASA application in the previous order to the called FASA application. Output.

Tag may be given, for example, before inputting the FASA platform or at the time of inputting the FASA platform or a predetermined FASA application. Switching corresponds to a change in the Tag itself or a change in the FASA application corresponding to the Tag. A plurality of Tag destinations may be sequentially assigned, or may be assigned for each division when the data is divided and processed. As the tag is given, all the destinations may be given, or a plurality of (for example, up to several destinations) may be given. When a plurality of tags are attached, it is desirable that the communication device 1 removes the transferred Tag so that the FASA application to which the data has been transferred can be identified, or assigns a mark indicating that the tag has been transferred.

Here, the output of the actual data has been mainly described, but the communication device 1 outputs information indicating the data storage location (for example, the address of the data storage destination), and is based on the information output by each FASA application. Data may be processed on the storage location specified by. When the tag is given by the component, it is necessary to convey the information for giving the tag to the FASA application. As a method of communication, the function of granting a tag (for example, a granting unit) may refer to a list such as a table every time when a tag is granted, a predetermined number of times, or a predetermined time elapses, or a FASA application. It may be referred to or read at the time of replacement / addition / deletion of, or updater such as FASA application or board startup / reboot / Liveupdate.

When granting in a common part such as SW or CONT version, it is the same as above to inform the granting place. When a tag is added by Forwarding-Engine, SW, or the like, it may be set at the time of replacement / addition / deletion of a FASA application or updater such as startup / reboot / Liveupdate of a FASA application or a board to Forwarding-Engine or the like.

In this operation example, if the tag of the application to be switched is not given or does not respond, the tag of the application in the next order is given, or the process that takes time to switch the application is discarded. (1) Setting request or deletion request Alternatively, the change request or response request is dealt with. Specifically, when there is no switching or response, the tag may be given or discarded in the next order to the FASA application or the function in the FASA platform, or in the FASA application or the function in the FASA platform. Tag may be added or discarded in the following order by the function of passing the processing of.

Waiting for the call of the application until the switching of the application to be switched is completed. Tag granting or waiting for the call in the application in the order prior to the application related to the process that takes time for the application to switch Tag granting or waiting at the beginning or in the middle of the correspondence table. (2) The setting request or the deletion request or the change request or the response request is held, and the held request corresponds to the input to the changed response unit 3 or the setting unit 4. Specifically, when there is no switching or response, it may be passed to the FASA application or the function in the FASA platform to be retained, or the function to pass the processing in the FASA application or the function in the FASA platform within the FASA platform. May be retained.

When the switching application or the call is not answered, the tag assignment of the proxy response application that outputs a predetermined value corresponds to (3) proxy response.
Specifically, (1) Granting a branched Tag that switches to another table or list of Tag that skips the application when switching or does not respond, or skips the application. (2) When switching or not responding, the processing request or the intermediate result of the processing and the processing itself are accumulated without giving or giving a tag, and when the switching is completed or the response is completed, the processing is started or restarted. (3) A branch process of switching to a table or list of tags of an application that responds by proxy when switching or not responding, or assigning a tag to jump to an application that responds by proxy. Specifically, when there is no switching or response, it may be passed to the FASA application or the function in the FASA platform that responds by proxy, or the function to pass the processing in the FASA application or the function in the FASA platform within the FASA platform. You may make a proxy response with.

Further, the table, list, and tag may be separately stored in the communication device 1 for each parallel process, or may be shared by a plurality of processes. If it is held separately, it is easy to record the data distribution status for each table, list, or tag, and if it is shared, it is desirable that the communication device 1 separately holds a record for the data distribution status for each process. Although the output of the actual data has been mainly described here, the communication device 1 outputs information indicating the data storage location (for example, the address of the data storage destination), and the information output by each FASA application. Data may be processed on the storage location specified based on.

In this case, there is an effect that the amount of output data can be reduced. In particular, the communication device 1 has an effect that the amount of data to be output can be reduced when the actual data is output to the FASA application instead of the index representing the storage location of the data. It is desirable that a plurality of processes are performed in parallel by pipeline processing or the like.

Further, the table or list may be separately held in the communication device 1 for each parallel process, or may be shared by a plurality of processes. If it is held separately, it is easy to record the data distribution status for each correspondence table, and if it is shared, it is desirable that the communication device 1 separately holds a record regarding the data distribution status for each process. Further, Forwarding-Engine, SW, or the like may be used to transfer data to the FASA application. The use of Forwarding-Engine, SW, or the like is particularly suitable when the data is in a predetermined frame format. Although the output of the actual data has been mainly described here, the communication device 1 outputs information indicating the data storage location (for example, the address of the data storage destination), and the information output by each FASA application. Data may be processed on the storage location specified based on.

(6th operation example)
As a sixth operation example, the communication device 1 is based on the data output from the external device or the ONU or the OLT internal or the FASA platform or the FASA application via the FASA-API or the tag associated with the address indicating the storage location of the data. Then, the FASA application corresponding to Tag performs the processing. For example, the FASA application scans the Tag during the processing time allocated to the FASA application to process the data to be processed by the FASA application. Switching corresponds to a change in the Tag itself or a change in the FASA application corresponding to the Tag.

Tag may be given, for example, before inputting the FASA platform or at the time of inputting the FASA platform or a predetermined FASA application. A plurality of Tag destinations may be sequentially assigned, or may be assigned for each division when the data is divided and processed. As the tag is given, all the destinations may be given, or a plurality of (for example, up to several destinations) may be given. When a plurality of tags are attached, it is desirable that the outgoing communication device 1 removes the transferred Tag so that the FASA application to which the data has been transferred can be identified, or assigns a mark indicating that the tag has been transferred.

Here, the output of the actual data has been mainly described, but the communication device 1 outputs information indicating the data storage location (for example, the address of the data storage destination), and is based on the information output by each FASA application. Data may be processed on the storage location specified by. When the tag is given by the component, it is necessary to convey the information for giving the tag to the FASA application. As a method of communication, the function of granting a tag (for example, a granting unit) may refer to a list such as a table every time when a tag is granted, a predetermined number of times, or a predetermined time elapses, or a FASA application. It may be referred to or read at the time of replacement / addition / deletion of, or updater such as FASA application or board startup / reboot / Liveupdate.

When granting in a common part such as SW or CONT version, it is the same as above to inform the granting place. When a tag is added by Forwarding-Engine, SW, or the like, it may be set at the time of replacement / addition / deletion of a FASA application or updater such as startup / reboot / Liveupdate of a FASA application or a board to Forwarding-Engine or the like.

In this operation example, if the tag of the application to be switched is not given or does not respond, the tag of the application in the next order is given, or the process that takes time to switch the application is discarded. (1) Setting request or deletion request Alternatively, the change request or response request is dealt with. Specifically, when there is no switching or response, the tag may be given or discarded in the following order to the FASA application or the function in the FASA platform, or in the FASA application or the function in the FASA platform. The following tags may be added or discarded by the function of passing the processing.

Waiting for the call of the application until the switching of the application to be switched is completed. Tag granting or waiting for the call in the application in the order prior to the application related to the process that takes time for the application to switch Tag granting or waiting at the beginning or in the middle of the correspondence table. (2) The setting request or the deletion request or the change request or the response request is held, and the held request corresponds to the input to the changed response unit 3 or the setting unit 4. Specifically, when there is no switching or response, it may be passed to the FASA application or the function in the FASA platform to be retained, or it may be retained by the function to pass the processing in the FASA application or the function in the FASA platform in the FASA platform. You may.

When the switching application or the call is not answered, the tag assignment of the proxy response application that outputs a predetermined value corresponds to (3) proxy response.
Specifically, (1) Granting a branched Tag that switches to another table or list of Tag that skips the application when switching or does not respond, or skips the application. (2) When switching or not responding, the processing request or the intermediate result of the processing and the processing itself are accumulated without giving or giving a tag, and when the switching is completed or the response is completed, the processing is started or restarted. (3) A branch process of switching to a table or list of tags of an application that responds by proxy when switching or not responding, or assigning a tag to jump to an application that responds by proxy.

You may make a proxy response with.

Further, the table, list, and tag may be separately stored in the communication device 1 for each parallel process, or may be shared by a plurality of processes. If it is held separately, it is easy to record the data distribution status for each table, list, or tag, and if it is shared, it is desirable that the communication device 1 separately holds a record for the data distribution status for each process.

If it is held separately, it is easy to record the data distribution status for each correspondence table, and if it is shared, it is desirable that the communication device 1 separately holds a record regarding the data distribution status for each process. Further, Forwarding-Engine, SW, or the like may be used to transfer data to the FASA application. The use of Forwarding-Engine, SW, or the like is particularly suitable when the data is in a predetermined frame format.

Data may be processed on the storage location specified based on.

The communication device 1 enables data transfer between the modules shown in FIG. 9 by performing any of the above-mentioned first to sixth operations. In the above description, the FASA application provided in the communication device 1 (OLT) has been illustrated and described, but data transfer may be performed by software constituting the FASA board, the FASA board itself, an ONU, another OLT, or an external device. Good.

Next, a multicast application will be described as an example.
Here, the main signal corresponds to the multicast stream, and the setting request and the response request are input from the Join or Leave such as IGMP or MLD input from the user side device, or from the server. When Joins and Leaves such as IGMP and MLD arrive via the main signal, those messages may be distributed, transferred, or copied to the main signal processing unit 2.
The applications to be added / replaced / deleted are, for example, a multicast function, an audience rating function, a Join filter function, a monitoring function, a multicast function + audience rating function, a multicast function + one filter function, and a multicast function + monitoring function.

The multicast function may be a server such as IGMP or MLD that terminates Join, Leave, etc., or receives a connection disconnection instruction from a multicast server, distribution server, controller, etc. to block the continuity of multicast traffic or duplicate it. You may start or stop, or change the transmission blocking of the filter.
In the audience rating function, for example, the number of terminals that can be viewed is calculated by acquiring and dividing the number of terminals that are being viewed or its log, or the number of terminals that are being viewed or its log is calculated. Output to the function to be performed or to an external device.

The Join filter identifies the attacking source terminal or other terminals and blocks a large number of IGMP messages from the attacking source terminal. The blocking may include, for example, an interface that can be set based on monitoring or an abnormality report, or may stop the distribution by identifying the address of the other party who sends the Join at a frequency equal to or higher than the threshold value. For example, the application periodically performs a Status Request / Reply for a forwarding engine such as Openflow loaded in the OLT on the order of 0.1 to several seconds to acquire statistical information, and determines the Joint message frequency for each address as a controller. When reporting to EMS etc. and detecting a frequency higher than the predetermined frequency, the forwarding of the Join message of the address is stopped, the distribution server is requested to stop the delivery to the address, and the frequency is as follows. When the detection of is more than a predetermined time, the forwarding of the Join message of the address is restarted, and the suspension of the delivery to the address to the distribution server is released. If this function is not available, the distribution server will be overloaded by the DoS attack by Join, but it will not be overloaded by adding the function.

The monitoring function is a function of monitoring a test terminal or the like by transferring a copy of Join, Leave or the like or a log thereof to a test terminal or the like when an abnormality is detected or an abnormality is serious. In the present embodiment, the response unit 3 or the setting unit 4 corresponds to a setting change corresponding to a multicast Join, Leave, etc., an audience rating function, a function to set a Join filter, and a function to perform monitoring setting. In the present embodiment, the communication device 1 performs the following processes (1) to (3).
(1) The switching unit 5 receives a change request or a response request (Join or response request) when switching the response unit 3 or the setting unit 4 (a function corresponding to a setting change corresponding to a multicast Join or Leave or a request from a controller or the like). Leave, etc.) is discarded.

(2) The switching unit 5 holds a change request or a response request when the response unit 3 or the setting unit 4 is switched, and inputs the held request to the changed response unit 3 or the setting unit 4. It is desirable to discard the request that is no longer needed due to the elapse of a predetermined time, the resend of the request due to a timeout or the like, or the change in the situation. The changing situation is, for example, setting items and functions that are present before the replacement but not after the replacement. Specifically, it is a setting or function related to the audience rating calculation of the audience rating function prepared before switching, the transfer of viewing information to the calculating device, the filter setting of the Join filter, and the transfer of the monitoring function, and is not prepared after switching. Settings and functions of things.

(3) The switching unit 5 includes a function unit that processes a change request or a response request when the response unit 3 or the setting unit 4 is switched, and the function unit responds on behalf of the response unit 3 or the setting unit 4. The proxy response may be provided in another device on the main signal, for example, a higher-level switch, if the request flows on the main signal path, or another device on the path if the request flows outside the main signal path. Do. The outside of the main signal path is, for example, a controller or the like. Further, it may be an application in which only predetermined settings and responses are performed and switching is easy, a platform such as middleware in which the application is arranged may be used, or the main signal processing unit 2 may be used. .. In this way, when the application is replaced, a new subscription / withdrawal responds by stopping, suspending, or acting as a proxy, but by making the main signal itself conductive, it is possible to replace the application without interrupting the service.
Although the above description has been made using an application as an example, software components other than the application may be used, and the components may be hardware.

The communication device 1 is a communication device that executes communication with another communication device by, for example, a signal such as an optical signal passing through a communication network such as an optical fiber network such as PON. The communication device 1 is, for example, an OLT (Optical Line Thermal: optical subscriber line end station device). The communication device 1 may be, for example, an OSU (Optical Subscriber Unit). The communication device 1 may be, for example, a combination of an OLT having or not having a switch unit (SW) for switching an optical signal and another switch unit (SW). The communication device 1 may be, for example, a combination of an OLT and an ONU (Optical Network Unit: optical network unit). The communication device 1 may include a plurality of devices. Further, it may be another communication device such as an ONU, a MUX (multiplexer), a DEMUX (demultiplexer), or a switch.

Next, as an example, the operation and the like will be illustrated on the assumption that the communication device 1 is a PON OLT conforming to the ITU-T recommendation such as a TWDM (Time and Wavelength Division Multiplex) -PON system. Here, TWDM-PON is used, but the PON may be a PON other than the TWDM-PON conforming to the ITU-T recommendation. For example, the PON may be an IEEE standard compliant PON such as GE (Gigabit Ethernet®-PON, 10 GE-PON, etc.). The TC (Transmission Convergence) layer and the PMD (Physical Medium Dependent) layer are the same if they are read as the corresponding layers in the standard.

The communication device 1 includes hardware or software, or a combination thereof, or a componentized function thereof. For example, the communication device 51 is realized by using a general-purpose input / output interface (for example, FASA (Flexible Access System Architecture) application API), which has different functions for each service or each communication carrier. An access that provides an application that is a software component (for example, a FASA application) and a function that does not need to be changed according to a service or request because the application is provided with the generalized input / output interface and is standardized. It includes a basic component of a network device (for example, a FASA board). Here, by using a general-purpose input / output interface, it is easy to add or replace functions, and services of various requests can be provided flexibly and promptly. In addition, in this specification, an application is also referred to as an "application".

The exchange between the parts is performed, for example, via the middleware unit 120 described later, but the original transfer path or means of the communication device 51 may be used, OpenFlow, Netconf / YANG, or SNMP (Simple Network Management Protocol). You may use standardized means such as.

Further, the communication between the parts may be any of the routes such as internal wiring, backboard, OAM unit, main signal line, dedicated wiring, operation system, controller or control panel (Cont panel). When the communication between parts is directly terminated and input, it may be encapsulated in the OAM unit or the main signal. Communication between parts may be terminated at any point and input via a route such as internal wiring, backboard, OAM section, main signal line, dedicated wiring, operation system, controller or control panel. .. When using the OAM section or the main signal line, it is desirable to encapsulate it in the OAM section or the main signal. When passing through the main signal line, it is desirable to distribute it at the OSU or the switch section at another location.

In this embodiment, the communication device 1 further includes an interface for receiving software components in an application such as a FASA application or a platform such as a FASA platform.

Interfaces are, for example, related to lists and tables related to data transfer. If the FASA application holds them, it is an interface that conveys them all to the FASA application. It is an interface for the FASA infrastructure to hold and refer to them when the FASA application refers to them. When a tag, a mark, or an address chain is used, it is an interface related to the tag where the tag, the mark, or the address chain to be used is given, interpreted, or processed. The interface is an interface for the FASA application when the tag or mark is changed or modified. Further, the interface is an interface for notifying a destination according to the history when the progress history of the FASA application of data is used.

(Embodiment 1-1)
In the first embodiment, the configuration of the communication device constituting the communication system used for the TWDM-PON will be described. The communication device described in the 1-1 embodiment is used as the communication device 1 shown in FIG. Hereinafter, examples 1 to 6 will be described as examples of the architecture of the communication device. The architecture of the communication device constituting the communication system may be an architecture other than the first to sixth examples described below. For example, the software part of the communication device in the first to sixth examples of the architecture may be a hardware part.

(First example of architecture)
FIG. 3 is a diagram showing a first example of the architecture of the communication device. In the first example of the architecture, the communication device has a non-general-purpose device-dependent section 110 whose operation depends on the device, a middleware section 120 which hides the difference in hardware and software of the device-dependent section 110, and a device-dependent operation. It is provided with a general-purpose device-independent application unit 130 that does not. Therefore, the device-dependent section 110 (vendor-dependent section) is a functional section that depends on the standard to which the device of the communication device conforms and the manufacturing vendor of the device. In other words, the device-dependent unit 110 has low compatibility with other communication devices, and cannot be used as it is for newly manufactured communication devices (particularly, devices having different conforming standards or manufacturing vendors). The device-dependent unit 110 executes one or more functions provided in the network device.

Further, the device-independent application unit 130 is a functional unit that does not depend on the standard to which the device of the communication device conforms or the manufacturing vendor of the device. In other words, the device-independent application unit 130 has high compatibility with other communication devices, and can be used as it is for newly manufactured communication devices (particularly, devices having different conforming standards and manufacturing vendors). Specific examples of the application provided in the device-independent application unit 130 include an application that performs setting processing in a network device, an application that performs setting change processing, an application that performs algorithm processing, and the like.

The middleware unit 120 and the device-independent application unit 130 are connected via the device-independent API 21. The device-independent API 21 is an input / output IF that does not depend on the device.

The device-dependent unit 110 includes, for example, a hardware unit 111 (PHY), a hardware unit 112 (MAC), a software unit 113, and an OAM (Operation Management and Management) unit 114. The hardware unit 111 (PHY), the hardware unit 112 (MAC), the software unit 113, the OAM unit 114, and the middleware unit 120 are connected via the device-dependent API 23. The device-dependent API 23 is a device-dependent input / output IF. The device-dependent unit 110 further includes a NE (Network Element) management / control unit 115. The NE management / control unit 115 and the middleware unit 120 are connected via the device-dependent API 25. The device-dependent API 25 is an input / output IF that depends on the device.

What kind of function is the device-dependent unit 110 or the device-independent application unit 130 is derived from the limitation derived from the processing for realizing the middleware unit 120 or the device-independent application unit 130, for example, the processing capacity of the software. In addition to the restrictions to be applied, it may be determined according to the frequency of function updates, the importance of extended functions, and the like. As a result, the communication device can facilitate the flexible and quick addition of the extended function unit (unique function unit) by the device-independent application unit 130, and can provide the communication service in a timely manner.

For example, priority processing of the main signal and functions that contribute to communication service differentiation or functions that are frequently updated, such as DBA (Dynamic Bandwidth Assignment) that improves line utilization efficiency, are prioritized and device-dependent unit 110 or device-independent. You may decide to use the application unit 130. Further, the device-independent application unit 130 may be used because the difference is small with respect to at least one of the standard, generation, method, system, device type, and manufacturing vendor to which the device to be shared conforms.

Any of the compliant standards, generations, methods, systems, equipment types, manufacturing vendor features, even if it is not optimal for at least one of the compliant standards, generations, methods, systems, equipment types, and manufacturing vendors. In order to generalize the above, a common IF for executing the function may be used. The common IF may include IFs and parameters that are not used in any of the standards, generations, methods, systems, device types, and manufacturing vendors to which the device-dependent unit 110 conforms.

The middleware unit 120 shown in FIGS. 3 and 4 described later, the driver of the device-dependent unit 110 shown in FIGS. 5 and 6 described later, and the device-dependent application unit 150 shown in FIGS. 4 and 6 described later ( In at least one of the vendor-dependent application section), there is a conversion function section that converts IFs and parameters to correspond to the device-dependent section 110, and a function section that automatically sets the missing IFs and parameters. You may prepare.

The device-dependent unit 110 shown in FIG. 3 includes a hardware unit 111 (PHY), a hardware unit 112 (MAC), and a software unit 113. The hardware unit 111 (PHY) executes from the physical layer to the processing related to optical transmission / reception (PHYsical sublayer processing). The hardware unit 112 (MAC) executes a MAC (Media Access Control) process. The hardware unit 111 (PHY) and the hardware unit 112 (MAC) depend on conforming standards and manufacturing vendors. The software unit 113 executes device-dependent drivers, firmware, applications, and the like.

In addition to these, the hardware unit 111 (PHY) and the hardware unit 112 (MAC) of the device-dependent unit 110 may include a general-purpose server, a layer 2 switch, and the like. The device-dependent unit 110 does not have to include the hardware unit 112 (MAC). The device-dependent unit 110 does not have to include a part of the hardware unit 111 (PHY). For example, the device-dependent unit 110 may have only optical-related functions without providing low-level signal processing such as modulation / demodulation signal processing, forward error correction (FEC, Forward Error Correction), code decoding processing, and encryption processing. Good. The device-dependent unit 110 does not have to include a PCS (Physical Coding Sublayer) which is a part for encoding data. The device-dependent unit 110 does not have to include a PMA (Physical Medium Attitude) for serializing data and a PCS. The device-dependent unit 110 does not have to include a PMD connected to a physical medium. In the device-dependent unit 110, when the middleware unit 120 directly drives, controls, operates or manages the hardware unit 111 (PHY) and the hardware unit 112 (MAC) of the device-dependent unit 110 without going through the software unit 113. The software unit 113 may not be provided.

The device-independent application unit 130 includes, for example, the extended function units 131-1 to 131-3 (extended function A, extended function B and extended function C in FIG. 3), the basic function unit 132, and the management / control agent unit. It is provided with 133. The management / control agent unit 133 exchanges data from the EMS (Element Management System) 140.

In the figure, the EMS 140 and the external device 160 are connected to the device-independent application unit 130 via the middleware unit 120, but the EMS 140 and the external device 160 are not necessarily connected to the device-independent application unit 130 via the middleware unit 120. You don't have to. The EMS 140 and the external device 160 may be appropriately connected to the middleware unit 120 or may be directly connected to the device-independent application unit 130, if necessary. Further, although it is expressed as "connecting via the middleware unit 120", this expression is an expression from the viewpoint of the device-independent application unit 130. In reality, device-independent apps are connected to each other via the middleware unit 120 after the connection by hardware.

Hereinafter, matters common to the extended function units 131-1 to 131-3 will be referred to as "extended function unit 131" by omitting a part of the reference numerals. The EMS 140 is, for example, a NE controller. The device-independent application unit 130 may not include any of the extended function unit 131, the basic function unit 132, and the management / control agent unit 133, and the management / control agent unit 133 is the basic function unit 132. The management / control agent unit 133 may be included in the basic function unit 132 or the middleware unit 120.

The device-independent application unit 130 may further include a configuration other than the extended function unit 131, the basic function unit 132, and the management / control agent unit 133. For example, when the extended function unit 131 is unnecessary, the device-independent application unit 130 does not have to include the extended function unit 131. Further, the device-independent application unit 130 may include one or more extended function units 131.

It is preferable that the extended function unit 131 can be added, deleted, replaced or changed independently without unnecessarily affecting other functions. For example, the extension function unit 131 may be added, deleted, replaced, or changed as appropriate when, for example, a multicast service or an extension function unit 131 that executes power saving measures is required according to a service request. ..

The basic function unit 132 may be included in the device-independent application unit 130 as a part of the extended function unit 131, or may be replaced by a function unit lower than the middleware unit 120. When the extended function unit 131 includes the basic function unit 132, the device-independent application unit 130 does not have to include the basic function unit 132. When a functional unit lower than the middleware unit 120 replaces the basic function unit 132, the device-independent application unit 130 does not have to include the basic function unit 132. When the extended function unit 131 includes the basic function unit 132 and the function unit lower than the middleware unit 120 substitutes for the basic function unit 132, the device-independent application unit 130 does not have to include the basic function unit 132.

When the management / control agent unit 133 does not receive communication from the EMS 140 and automatically sets according to a predetermined setting, the management / control agent unit 133 does not have to input / output with the EMS 140. Further, when the management / control agent unit 133 does not have the management setting function and the other device-independent application unit 130, the basic function unit 132, or the device-dependent unit 110 has the management setting function, the device-independent application unit 130 The management / control agent unit 133 may not be provided.

Information may be directly input / output between the EMS 140 and the device-independent application unit 130. Further, the device-dependent unit 110 may be replaced by the NE management / control unit 115 and the device-dependent application unit 150 (see FIG. 4 and FIG. 6 to be described later) which is a lower function unit of the NE management / control unit 115. Good.

When the management / control agent unit 133 automatically sets according to a predetermined setting, it is not necessary to input / output information to / from the EMS 140. Further, when the management / control agent unit 133 does not have the management setting function and the other device-independent application unit 130, the basic function unit 132, or the device-dependent unit 110 has the management setting function, the device-independent application unit 130 manages. -The control agent unit 133 does not have to be provided. Information may be directly input / output between the EMS 140 and the device-independent application unit 130.

An example of input / output between the device-independent application unit 130 and the device-dependent unit 110 is as follows.
For example, the DBA application unit and the protection application unit input / output information to and from the embedded OAM engine (Embedded OAM Engine) of the TC layer. The DWBA (Dynamic Wavelength and Bandwidth Authentication) application and the ONU registration authentication application unit input / output information to and from the PLOAM engine of the TC layer. The power saving application unit inputs / outputs information to and from the OMCI and the L2 main signal processing function unit (L2 function unit). The MLD (Multicast Listener Discovery) proxy application unit inputs and outputs information to and from the L2 functional unit. The low-speed monitoring application (OMCI) inputs and outputs information to and from OMCI. The OMCI and L2 functional units operate the XGEM framer (XGPON Encapsulation Method Framer) and encryption. Here, DWBA and DBA may be separate, integrated, or combined. For example, the management / control agent unit 133 is an application unit of the maintenance operation function, and inputs / outputs information to and from EMS140, which is an NE controller or the like for the NE management / control unit 115.

The implementation of the device-independent application unit 130 may have a priority. For example, the management / control agent unit 133 has the highest priority. Below the second priority is, for example, a DBA application, a DWBA application, a power saving application, an ONU registration authentication application, an MLD proxy application, a protection application, and a low-speed monitoring application (OMCI).

The device-independent application unit 130 uses the device vendor, method, device type, device generation, for example, ITU-T G.M. TWDM-PON conforming to the 989 series and ITU-T G. XG-PON conforming to the 987 series and ITU-T G. G-PON conforming to the 984 series and ITU-T G. It is an application that operates regardless of the B (Broadband) PON conforming to the 983 series. The device-independent application unit 130 differs in device vendor, method, device type, device generation, for example, 10GE-PON conforming to IEEE802.3av and IEEE1904.1, and GE-PON conforming to IEEE802.3ah. It is an application that works regardless of.

As the application of the extended function unit 131, only the application for driving the functions prepared for some vendors, methods, types, and generations and the devices of some vendors, methods, types, and generations via the device-independent API 21. It may include an app that drives the features provided for.

The management / control agent unit 133 inputs / outputs to and from the EMS 140 and the middleware unit 120. The middleware unit 120 inputs / outputs NE management information and control information to / from the NE management / control unit 115. The NE management / control unit 115 may directly transmit / receive NE management information and control information to / from the EMS 140 without going through the middleware unit 120, or may send / receive NE management information and control information via the management / control agent unit 133. You may send and receive.

The middleware unit 120 inputs / outputs information via the device-independent application unit 130 and the device-independent API 21. The middleware unit 120 inputs / outputs information to / from the OAM unit 114 of the device-dependent unit 110, the driver, the firmware, the hardware unit 111 (PHY), or the hardware unit 112 (MAC) via the device-dependent API 23. The middleware unit 120 outputs the input information as it is or in a predetermined format. For example, if the output destination is each part of the device-independent application unit 130, the middleware unit 120 converts the information into the input format of each part of the device-independent API 21. If the output destination is the OAM unit 114 of the device-dependent unit 110, the driver, the firmware, the hardware unit 111 (PHY) or the hardware unit 112 (MAC), the middleware unit 120 is the device-dependent API 23 in the form of input to each. After converting to the format, or after terminating and performing the predetermined processing, the information is transmitted to the output destination.

At the time of input, the middleware unit 120 deletes unnecessary input information at each input destination, and if there is insufficient information, it can collect and supplement it via another device-independent API 21 or device-dependent API 23. desirable. Further, when inputting to the middleware unit 120, it may be broadcast or multicast to broadcast to a related application or the like.

In FIG. 3, the middleware unit 120 and the device-dependent unit 110 are illustrated as a single unit, but each may be composed of a plurality of units. When the hardware of the device-dependent unit 110 includes a plurality of processors, the middleware unit 120 may input / output using interprocessor communication or the like across the processors and hardware. The device-independent application unit 130 and the device-independent application unit 130 may be arranged in the user space on a single processor as an execution program such as a DLL (Dynamic Link Library), or on a plurality of processors. It may be arranged in the user space.

Further, the device-independent application unit 130 may be arranged in the kernel space after securing input / output IFs such as API, or may be arranged together with the middleware unit 120 having an IF that can be independently replaced with firmware or the like. Alternatively, it may be incorporated into firmware or the like and recompiled. The user space and kernel space may be any combination for each device-independent application unit 130.
The device-independent application unit 130 corresponding to the same function may be implemented in both the user space and the kernel space. In this case, for example, it may be switched and either one may be selected, both may be processed in cooperation, or the actual processing may be performed by only one of them. The same applies to the software of the device-dependent unit 110.

Desirably, the more high-speed processing such as main signal processing, DBA processing, and low-layer signal processing is required, the more there is a trade-off with the immediacy of expandability / replacement, but high-speed processing with less overhead is expected. It is desirable to incorporate it in the kernel space or firmware. The processor in which the device-dependent application unit 150 (see FIG. 4 and FIG. 6 to be described later) is arranged is also actual from the viewpoint of the influence on other programs due to the limitation of the bus and speed due to the inter-processor communication and the occupation of the communication path. It is desirable to place it in the user space, kernel space, or firmware of the processor that performs processing or a processor in the vicinity thereof. However, in order to reduce the capacity of the processor performing the actual processing or a processor in the vicinity thereof, the communication cost due to the inter-processor communication increases, but the processing may be performed by a remote processor.

It is desirable that the device-independent API 21 is provided in the middleware unit 120 in advance assuming the extended function unit 131 to be added, but it is necessary in a form of suppressing modification of the device-dependent API 23 and other device-independent application units 130. It may be added or deleted accordingly.

In this example, the softened area is the basic function unit 132, the management / control agent unit 133, the extended function unit 131, and the middleware unit 120, but the softened area is the service adaptation (encryption, fragment processing, GEM). Framed / XGEM framing, PHY adaptation FEC, scrambling, synchronous block generation / extraction, GTC (GPON Forward Convergences) framing, PHY framing, SP conversion, and encoding methods may also be targeted. Architecture softening function An example of implementation and an example of function deployment corresponding to the hardware unit will be described. The function deployment includes, for example, a software function in a network device or an external server. This is the same in other examples.

(Second example of architecture)

Further, when the management / control agent unit 133 does not have the management setting function and the other device-independent application unit 130, the basic function unit 132, or the device-dependent unit 110 has the management setting function, the device-independent application unit 130 The management / control agent unit 133 may not be provided.

The EMS 140 and the device-independent application unit 130 may be directly input / output. When the lower level of the middleware unit 120 replaces all of the basic function unit 132, the device-independent application unit 130 does not have to include the basic function unit 132.

In the communication device shown in FIG. 4, the device-dependent application unit 150 may input / output information via the middleware unit 120, or may directly input / output information from the management / control agent unit 133, or both. Information may be input / output to / from any of the above, or may be directly input / output to / from EMS140. Further, when the device-dependent application unit 150 is automatically set according to a predetermined setting without receiving communication from the EMS 140, and management and control information can be acquired from the EMS 140 via the middleware unit 120, the device The independent application unit 130 does not have to include the management / control agent unit 133.

The device-independent application unit 130 inputs information via the middleware unit 120 at least between the hardware unit 111 (PHY) and the hardware unit 112 (MAC) of the device-dependent unit 110 or between the software unit 113. Output. The device-independent application unit 130 inputs / outputs to and from each other via the middleware unit 120 as needed. In particular, when the device-independent application unit 130 executes control or management according to the information input / output to / from the EMS 140, the device-independent application unit 130 transfers the information to / from the management / control agent unit 133 that receives communication from the EMS 140. Input / output.

The NE management / control unit 115 inputs / outputs NE management information and control information to / from the management / control agent unit 133 via the middleware unit 120. The NE management / control unit 115 may directly input / output NE management information and control information to / from the EMS 140 without going through the middleware unit 120.

The device-dependent application unit 150 inputs / outputs NE management information and control information to / from the management / control agent unit 133. The device-dependent application unit 150 may directly input / output information to / from the EMS 140 without going through the management / control agent unit 133.

Information is input / output to / from the hardware unit 112 (MAC) via the device-dependent API 23.

The middleware unit 120 shown in FIG. 4 is input as it is or in a predetermined format, similarly to the middleware unit 120 shown in FIG. It is desirable that the device-independent API 21 is provided in the middleware unit 120 in advance assuming the extended function unit 131 to be added later, but if necessary, the device-dependent API 23 and other device-independent application units 130 may be modified. It may be added or deleted in a suppressed form.

(Third example of architecture)
FIG. 5 is a diagram showing a third example of the architecture of the communication device. In FIG. 5, instead of the middleware unit 120 described in the first example of the architecture shown in FIG. 3, the basic function unit 132 is the hardware unit 111 (PHY), the hardware unit 112 (MAC), and the extended function unit 131. Input and output with. The other device-independent application unit 130 is the same as the first example of the architecture.

In the figure, the EMS 140 and the external device 160 are connected to the device-independent application unit 130 via the basic function unit 132, but the EMS 140 and the external device 160 are not necessarily the device-independent application via the basic function unit 132. It is not necessary to connect to the unit 130. The EMS 140 and the external device 160 may be appropriately connected to the middleware unit 120 or may be directly connected to the device-independent application unit 130, if necessary. Further, although it is expressed as "connecting via the middleware unit 120", this expression is an expression from the viewpoint of the device-independent application unit 130. In reality, device-independent apps are connected to each other via the middleware unit 120 after the connection by hardware.

Compared to the first example of the architecture, the third example uses the middleware unit 120 including the device-dependent APIs 23 and 25 for each device having at least one of a compliant standard, generation, method, system, device type, and manufacturing vendor. No need to create. As a result, the communication device of the third example of the architecture has the effect of generalizing and porting more functions between generations between devices, facilitating verification of connectivity, and making the functions of the devices robust.

The communication device according to the third example of the architecture includes a device-dependent unit 110 and a device-independent application unit 130. The device-dependent section 110 includes a hardware section 111 (PHY) and a hardware section 112 (MAC), and a hardware section 111 (PHY) and a hardware section 112 (MAC), which depend on a compliant standard or a device manufacturing vendor. It is provided with a software unit 113 such as a driver and firmware for driving the device. The driver or the like hides the difference in the device-dependent unit 110.

The device-independent application unit 130 includes an extended function unit 131 and a basic function unit 132. The basic function unit 132 uses a device-independent API 27 (IF for porting) via a driver that hides the difference between the hardware unit 111 (PHY) and the hardware unit 112 (MAC) and the device-dependent software unit 113. Connect with the dependent unit 110. The device-independent application unit 130 uses a driver that hides the difference between the hardware unit 111 (PHY) and the hardware unit 112 (MAC) and the device-dependent software unit 113, and then hardware unit 111 (PHY) and hardware. Data is input and output between the hardware unit 112 (MAC) and the device-dependent software unit 113.

The basic function unit 132 and the extended function unit 131 are connected via a device-independent API 22 (expansion IF). The basic function unit 132 and the device-dependent unit 110 are connected via the device-independent API 27. The basic function unit 132 of the device-independent application unit 130 inputs information between the hardware unit 111 (PHY), the hardware unit 112 (MAC), and the extended function unit 131 instead of the middleware unit 120. Output.

The device-independent application unit 130 inputs / outputs to and from each other via the basic function unit 132 as needed. The extended function unit 131 of the device-independent application unit 130 inputs / outputs information via the basic function unit 132 and the device-independent API 22. The basic function unit 132 inputs and outputs information via the extended function unit 131 and the device-independent API 22, and the OAM unit, driver, firmware, hardware unit 111 (PHY), and hardware unit 112 (MAC) of the device-dependent unit 110. ) And the device-independent API 27 to input and output information.

Similar to the middleware unit 120 shown in FIG. 3, the basic function unit 132 inputs information as it is or in a predetermined format. For example, in the case of another device-independent application unit 130, the basic function unit 132 converts the input format into the device-independent API 22 format, and the device-dependent OAM unit, driver, firmware, and hardware unit are used. If there is, the information is input after being converted into the device-independent API 22 format of the input format, or after being terminated and performing a predetermined process. At the time of input, the basic function unit 132 deletes unnecessary input information at each input destination, and if there is insufficient information, collects and supplements it via another device-independent API 22 or device-independent API 27. Is desirable. However, the basic function unit 132 may broadcast or multicast the input to the input destination to broadcast the input to the related application or the like.

The device-independent application unit 130 includes, for example, extended function units 131-1 to 131-3 and basic function units 132. The device-independent application unit 130 does not have to include either the extended function unit 131 or the basic function unit 132. The device-independent application unit 130 may further include functional units other than the extended function unit 131 and the basic function unit 132. For example, when the extended function unit 131 is unnecessary, the device-independent application unit 130 does not have to include the extended function unit 131.

It is preferable that the extended function unit 131 can be added or deleted independently without affecting other functions. For example, when the multicast service and power saving support are set to the extended function unit 131 according to the service request, the extended function unit 131 is added as needed when it is needed, and deleted as needed when it is no longer needed. However, it may be replaced or changed according to the change.

It is desirable that the device-independent API 22 is provided in advance in the basic function unit 132, assuming an extended function unit 131 to be added later, but if necessary, the device-independent API 22, the device-independent API 27, and other devices are not used. It may be added or deleted in a form that suppresses the modification of the dependent application unit 130.

(4th example of architecture)
FIG. 6 is a diagram showing a fourth example of the architecture of the communication device. The difference between the fourth example of the architecture and the third example of the architecture is that the communication device includes the device-dependent application unit 150 under the basic function unit 132. As described above, the communication device of the fourth example of the architecture has an effect that the configuration of the basic function unit 132 can be simplified by providing the device-dependent application unit 150.

The communication device shown in FIG. 6 includes a device-dependent unit 110 and a device-independent application unit 130. The device-dependent section 110 includes a hardware section 111 (PHY) and a hardware section 112 (MAC), and a hardware section 111 (PHY) and a hardware section 112 (MAC), which depend on a compliant standard or a device manufacturing vendor. It has a software unit 113 such as a driver and firmware to be driven, and a device-dependent application unit 150 that drives at least a part of the device-dependent unit 110. The device-independent application unit 130 uses a driver that hides the difference between the portable IF and the hardware unit 111 (PHY) and the hardware unit 112 (MAC) and the device-dependent software, or the portable IF and the device-dependent application. It is a general-purpose device-independent application that executes device-independent processing via the unit 150. The basic function unit 132 in the device-independent application unit 130 and the device-dependent application unit 150 in the device-dependent unit 110 are connected via the device-independent API 27. The device-dependent application unit 150 and the other functional units of the device-dependent unit 110 are connected via the device-dependent API 24.

In the basic function unit 132 in the device-independent application unit 130, the basic function unit 132 performs input / output with the hardware and the extended function unit 131 instead of the middleware unit 120. The basic function unit 132 may include a management / control agent unit 133 (see FIGS. 3 and 4) that receives communication from the EMS 140, and the management / control agent unit 133 is provided as the extension function unit 131. You may.

The basic function unit 132 inputs / outputs via the expansion function unit 131 and the device-independent API 22 (expansion IF), and the OAM unit, driver, firmware, hardware unit 111 (PHY), and hardware unit of the device-dependent unit 110. The driver of the device-dependent unit 110 or the device-dependent application unit 150 and the device-independent API 27 (porting) input / output via 112 (MAC) and the device-independent API 27 (porting IF) to hide the difference of the device-dependent unit 110. Input / output via IF).

The basic function unit 132 inputs as it is or in a predetermined format as in the middleware unit 120 shown in FIG. Similar to the third example of the architecture, the basic function unit 132 may include the management / control agent unit 133 corresponding to the communication from the EMS 140, or the management / control agent unit 133 as the extension function unit 131. You may prepare.

The device-independent application unit 130 includes, for example, extended function units 131-1 to 131-3 and basic function units 132. The device-independent application unit 130 does not have to include either the extended function unit 131 or the basic function unit 132, as in the third example of the architecture. The device-independent application unit 130 may further include functional units other than the extended function unit 131 and the basic function unit 132, as in the third example of the architecture.

It is preferable that the extended function unit 131 can be added, deleted, replaced or changed independently of each other without affecting other functions, as in the third example of the architecture. A part of the basic function unit 132 may be replaced by the device-dependent application unit 150. The device-dependent application unit 150 inputs / outputs information directly from the basic function unit 132, but even if the information is input / output to / from the EMS 140 as it is or after a predetermined conversion, the information is input / output from the basic function unit 132. Good.

Similar to the first example of the architecture shown in FIG. 3, it is desirable that the device-independent APIs 22 and 27 are provided in advance in the basic function unit 132, assuming an extended function unit 131 to be added later, but the device-independent API 22 , Device-independent API 27, other device-independent application unit 130, device-dependent application unit 150, or device-dependent API 24 may be added or deleted as necessary in a form of suppressing modification.

(5th example of architecture)
The upper right figure of FIG. 7 is a diagram showing a fifth example of the architecture. The lower right figure of FIG. 7 corresponds to the first to fourth examples of the architecture. The figure shows a case where the communication device is an OLT. The fifth example of the architecture is a function cloud that implements (cloud) the OLT function on the external hardware and makes use of the existing / commercial OLT hardware to prepare the function addition / change according to the service. It is suitable for taking a cloud computing approach.

In this example, the communication device consists of existing / commercial hardware and external hardware. For example, the existing / commercial hardware is a non-general-purpose device-dependent section 110 that depends on the device, and a middleware section 121 that hides the difference between hardware and software on the external hardware and a general-purpose section whose operation does not depend on the device. The device-independent application unit 130 is provided. Therefore, the device-dependent section (vendor-dependent section) below the middleware in the figure is a functional section that depends on the standard to which the device of the communication device conforms and the manufacturing vendor of the device. Further, the device-independent application unit 130 is a functional unit that does not depend on the standard to which the device of the communication device conforms or the manufacturing vendor of the device.

The middleware unit 121 and the device-independent application unit 130 are connected via a device-independent API, which is a device-independent input / output IF. For example, the software unit, OAM, hardware unit (PHY) and hardware unit (MAC) of the device-dependent unit 110, and the middleware unit 121 on the external hardware are device-dependent input / output IFs that depend on the device. It is connected via device-to-device connection between API and existing / commercial hardware and external hardware.

This architecture facilitates the flexible and quick addition of the extended function unit (unique function unit) by the device-independent application unit 130, and can provide the communication service in a timely manner. Here, the device-dependent unit 110 may be the maintenance operation, access control, physical layer processing, and optical modular shown in FIG. 7, and depends on the configuration of the device itself.

For example, the device-dependent unit 110 or the device-independent application unit 130 is designated as a device-dependent unit 110 or a device-independent application unit 130, giving priority to a function having a high update frequency such as DBA for improving main signal priority processing and line utilization efficiency or a function contributing to communication service differentiation. You may decide. Further, the device-independent application unit 130 may be used because the difference is small with respect to at least one of the standard, generation, method, system, device type, and manufacturing vendor to which the device to be shared conforms.

Any of the compliant standards, generations, methods, systems, equipment types, manufacturing vendor features, even if it is not optimal for at least one of the compliant standards, generations, methods, systems, equipment types, and manufacturing vendors. In order to generalize the above, a common IF for executing the function may be used. The common IF may include IFs and parameters that are not used in any of the standards, generations, methods, systems, device types, and manufacturing vendors to which the device-dependent unit 110 conforms.

A conversion function unit that converts IFs, parameters, etc. to at least one of the middleware unit 121, the driver of the device-dependent unit 110, and the device-dependent application unit 150 (vendor-dependent application unit) so as to correspond to the device-dependent unit 110. Alternatively, it may be further provided with a functional unit that automatically sets in response to insufficient IFs, parameters, and the like.

The device-dependent unit 110 includes a hardware unit and a software unit. The software section executes device-dependent drivers, firmware, applications, and the like.

The device-dependent unit 110 does not have to include a PMD connected to a physical medium, a MAC, a PMA for serializing data, and a part of PCS or PHY which is a part for encoding data. For example, it may have only optical-related functions without providing low-level signal processing such as modulation / demodulation signal processing, forward error correction (FEC), code decoding processing, and encryption processing.

The device-independent application unit 130 is, for example, a management / control agent unit 133 that acquires data from EMS, an extended function unit 131-1 to 131-3, and a basic function unit 132. Hereinafter, matters common to the extended function units 131-1 to 131-3 will be referred to as "extended function unit 131" by omitting a part of the reference numerals. EMS is, for example, a controller that controls network elements. The device-independent application unit 130 may not include any of the management / control agent unit 133, the extended function unit 131, and the basic function unit 132.

The device-independent application unit 130 may further include configurations other than the management / control agent unit 133, the extended function unit 131, and the basic function unit 132. For example, when the extended function unit 131 is unnecessary, the device-independent application unit 130 does not have to include the extended function unit 131. Further, the device-independent application unit 130 may include one or more extended function units 131.

It is preferable that the extended function unit 131 can be added, deleted, replaced or changed independently without unnecessarily affecting other functions. For example, the extension function unit 131 may be added, deleted, replaced, or changed as appropriate when, for example, a multicast service or an extension function unit 131 that executes power saving measures is required according to a service request. ..

The basic function unit 132 may be included in the device-independent application unit 130 as a part of the extended function unit 131, or may be replaced by a function unit lower than the middleware unit 121. When the extended function unit 131 includes the basic function unit 132, the device-independent application unit 130 does not have to include the basic function unit 132. When a functional unit lower than the middleware unit 121 substitutes for the basic function unit 132, the device-independent application unit 130 does not have to include the basic function unit 132. When the extended function unit 131 includes the basic function unit 132 and the function unit lower than the middleware unit 120 substitutes for the basic function unit 132, the device-independent application unit 130 does not have to include the basic function unit 132.

When the management / control agent unit 133 does not receive communication from the EMS 140 and automatically sets according to a predetermined setting, the management / control agent unit 133 does not have to input / output with the EMS 140. Further, when the management / control agent unit 133 does not have the management setting function and the other device-independent application unit 130, the basic function unit 132, or the device-dependent unit 110 has the management setting function, the device-independent application unit 130 The management / control agent unit 133 may not be provided.

Information may be directly input / output between the EMS 140 and the device-independent application unit 130. Further, the device-dependent unit 110 does not have to include the NE management / control unit 115 and the IF of the NE management / control unit 115.

The basic function unit 132 may be included in the device-independent application unit 130 as a part of the extended function unit 131, or may be replaced by a lower function unit of the middleware unit 120. When the extended function unit 131 includes the basic function unit 132, or when the lower function unit of the middleware unit 120 replaces the basic function unit 132 or is a combination thereof, the device-independent application unit 130 is the basic function unit. 132 may not be included. Further, a part of the basic function unit 132 may be replaced by the device-dependent application unit 150 of the lower function unit of the middleware unit 120.

When the management / control agent unit 133 automatically sets according to a predetermined setting, it is not necessary to input / output information to / from the EMS 140. Further, when the management / control agent unit 133 does not have the management setting function and the other device-independent application unit 130, the basic function unit 132, or the device-dependent unit 110 has the management setting function, the device-independent application unit 130 manages. -The control agent unit 133 does not have to be provided. Information may be directly input / output between the EMS 140 and the device-independent application unit 130.

An example of input / output between the device-independent application unit 130 and the device-dependent unit 110 is as follows. For example, the DBA application unit and the protection application unit input / output information to and from the embedded OAM engine of the TC layer. The DWBA application and the ONU registration authentication application unit input / output information to and from the PLOAM engine of the TC layer. The power saving application unit inputs / outputs information to and from the OMCI and the L2 main signal processing function unit (L2 function unit). The MLD proxy application unit inputs and outputs information to and from the L2 function unit. The low-speed monitoring application (OMCI) inputs and outputs information to and from OMCI. The OMCI and L2 functional units operate the XGEM framer and encryption. Here, DWBA and DBA may be separate, integrated, or combined. For example, the management / control agent unit 133 is an application unit of the maintenance operation function, and inputs / outputs information to and from EMS140, which is an NE controller or the like for the NE management / control unit 115.

The device-independent application unit 130 uses the device vendor, method, device type, device generation, for example, ITU-T G.M. TWDM-PON conforming to the 989 series and ITU-T G. XG-PON conforming to the 987 series and ITU-T G. G-PON conforming to the 984 series and ITU-T G. It is an application that operates regardless of any of the 983 series compliant BPON. The device-independent application unit 130 differs in device vendor, method, device type, device generation, for example, 10GE-PON conforming to IEEE802.3av and IEEE1904.1, and GE-PON conforming to IEEE802.3ah. It is an application that works regardless of.

As the application of the extended function unit 131, only the application for driving the functions prepared for some vendors, methods, types, and generations and the devices of some vendors, methods, types, and generations via the device-independent API 21. It may include an app that drives the features provided for.

The management / control agent unit 133 inputs / outputs to and from the EMS 140 and the middleware unit 120. The middleware unit 120 inputs / outputs NE management information and control information to / from the NE management / control unit 115. The NE management / control unit 115 may directly transmit / receive NE management information and control information to / from the EMS 140 without going through the middleware unit 120, or may send / receive NE management information and control information via the management / control agent unit 133. You may send and receive.

The middleware unit 120 inputs / outputs information via the device-independent application unit 130 and the device-independent API 21. The middleware unit 120 inputs / outputs information to / from the OAM unit 114 of the device-dependent unit 110, the driver, the firmware, the hardware unit 111 (PHY), or the hardware unit 112 (MAC) via the device-dependent API 23. The middleware unit 120 outputs the input information as it is or in a predetermined format. For example, if the output destination is each part of the device-independent application unit 130, the middleware unit 120 converts the information into the input format of each part of the device-independent API 21. If the output destination is the OAM unit 114 of the device-dependent unit 110, the driver, the firmware, the hardware unit 111 (PHY) or the hardware unit 112 (MAC), the middleware unit 120 is the device-dependent API 23 in the form of input to each. After converting to the format, or after terminating and performing the predetermined processing, the information is transmitted to the output destination.

At the time of input, the middleware unit 120 deletes unnecessary input information at each input destination, and if there is insufficient information, it can collect and supplement it via another device-independent API 21 or device-dependent API 23. desirable. Further, when inputting to the middleware unit 120, it may be broadcast or multicast to broadcast to a related application or the like.

The middleware unit 120 and the device-dependent unit 110 are illustrated as a single unit, but each may be composed of a plurality of units. When the hardware of the device-dependent unit 110 includes a plurality of processors, the middleware unit 120 may input / output across the processors and hardware by using interprocessor communication or the like. The device-independent application unit 130 and the device-independent application unit 130 may be arranged as an execution program such as DLL in the user space on a single processor, or arranged in the user space on a plurality of processors. You may.

Further, the device-independent application unit 130 may be arranged in the kernel space after securing input / output IFs such as API, or may be arranged together with the middleware unit 120 having an IF that can be independently replaced with firmware or the like. Alternatively, it may be incorporated into firmware or the like and recompiled. The user space and kernel space may be any combination for each device-independent application unit 130.

The device-independent application unit 130 corresponding to the same function may be implemented in both the user space and the kernel space. In this case, for example, it may be switched and one of them may be selected, both may be processed in cooperation, or the actual processing may be performed by only one of them. The same applies to the software of the device-dependent unit 110.

Desirably, the more high-speed processing such as main signal processing, DBA processing, and low-layer signal processing is required, the more there is a trade-off with the immediacy of expandability / replacement, but high-speed processing with less overhead is expected. It is desirable to incorporate it in the kernel space or firmware. The processor in which the device-dependent application unit 150 is arranged is also the user space of the processor that performs actual processing or a processor in the vicinity thereof from the viewpoint of the influence on other programs due to the limitation of the bus and speed due to the communication between the processors and the occupation of the communication path. It is desirable to place it in the kernel space or on the firmware. However, in order to reduce the capacity of the processor performing the actual processing or a processor in the vicinity thereof, the communication cost due to the inter-processor communication increases, but the processing may be performed by a remote processor.

It is desirable that the device-independent API 21 is provided in the middleware unit 120 in advance assuming the extended function unit 131 to be added, but it is necessary in a form of suppressing modification of the device-dependent API 23 and other device-independent application units 130. It may be added or deleted accordingly.

It includes a software unit 113 such as a driver and firmware that drives the unit 112 (MAC), and a device-dependent application unit 150 that drives at least a part of the device-dependent unit 110.

The device-dependent application unit 150 and the device-dependent unit 110 are connected via the device-dependent API 24. The device-dependent application unit 150 may include a management / control agent unit 133 that receives communication from the EMS 140. The device-dependent API 24 may be added or deleted as necessary in a form that suppresses modification of the device-dependent application unit 150 and the device-dependent API 24.

The configuration of the communication device shown in the first to sixth examples of the architecture of the communication device is described on the premise of the IEEE of the PON conforming to the ITU-T recommendation such as TWDM-PON, but it is an ONU. It may be either an OLT or an ONU of an PON conforming to the ITU-T recommendation other than TWDM-PON, or may be an IEEE standard compliant PON such as GE-PON and 10GE-PON, and TC. The same applies if the layer or PMD layer is read as the corresponding layer.

The processes that make up the maintenance and operation functions of the maintenance and operation function unit 330 include ONU, OSU, OLT, or SW device settings (manual, batch, automatic, operation trigger), setting backup, FW update, device control (reset), and redundancy. Has configuration support. These processes may consist of basic processes such as CLI-IF, device management IF, operation IF, general-purpose Config-IF (Netconf, SNMP, etc.), and table management. Equivalent processing may be realized by a combination of basic processing without providing device setting, setting backup, FW update, device control, and support for redundant configuration. Moreover, the order may be changed.

The main functions of the maintenance and operation function unit 330 are within 100 milliseconds from receiving the instruction to sending the ACK, and within 200 milliseconds from receiving the instruction to sending the reflection completion notification (however, setting backup including data transfer and FW update are performed. It is required to follow the regulations such as according to the scale (size / number of users). As an example of the division of functions, the processing may be performed by the application except for the hardware Config, and the software and setting data may be processed by the application on the external server 16 of FIG. 8 without being held by the ONU or OLT. It can also be realized by unifying commands and defining sequences.

FIG. 15 is a diagram showing a second example of the configuration of the function of the maintenance / operation function unit 330. As the processes constituting the functions of the maintenance / operation function unit 330, there are device status monitoring (CPU / memory / power supply / switching), traffic monitoring, alarm monitoring (ONU abnormality, OLT abnormality), and test (loopback). These processes may be composed of alarm notification, log recording, L3 packet generation / processing, and table management, which are basic processes. For device condition monitoring, traffic monitoring, alarm monitoring, and testing, equivalent processing may be realized by a combination of basic processing. Moreover, the order may be changed.

The main functions of the maintenance and operation function unit 330 are required to comply with regulations such as a latency of 100 milliseconds or less. As an example of function sharing, only the notification / display IF is used as an application, and items that require monitoring (CPU load, memory usage, power status, power consumption, Ethernet (registered trademark) link status, etc.) are in the device-dependent section 110. Yes, it is also possible to perform processing by an application that can turn off IF, such as reading a notification from the device-dependent unit 110, transmitting a notification via a network (NW), and writing to a file.

FIG. 16 is a diagram showing a third example of the functional configuration of the maintenance / operation function unit 330. As the processing that constitutes the maintenance operation function of the maintenance operation function unit 330, it has high-speed monitoring / control input / output (sleep instruction / reply, λ setting switching instruction / reply, etc.). As a means of this processing, a physical layer OAM (PLOAM: PHYsical Layer OAM) message and a bit display (Embedded OAM) in the header are used. These processes may be composed of PLOAM process, which is a basic process, Embedded OAM process, communication with the power saving control function unit 360, communication with the protection function unit 380, and communication with the PON access control function unit 320. For monitoring / control input / output that requires high speed, equivalent processing may be realized by a combination of basic processing. Moreover, the order may be changed. The main functions of the maintenance and operation function unit 330 are required to comply with regulations such as setting the PLOAM processing within 750 microseconds.

FIG. 17 is a diagram showing an example of a functional configuration of the PON multicast functional unit 350. As a process constituting the PON multicast function included in the PON multicast function unit 350, it includes identification or distribution of a multicast stream, MLD proxy / snooping, ONU filter setting, and inter-wavelength setting transition. These processes may consist of basic processes such as L2 identification / sorting, L3 packet processing (preferably provided with IPv6 Parse), L3 packet generation, table management, and communication with the OMCI function. Multicast stream identification or distribution, MLD proxy / snooping, ONU filter setting, and inter-wavelength setting transition may realize equivalent processing by a combination of basic processing. Moreover, the order may be changed.

In the text of this application, MLD is exemplified as a multicast protocol, but the same applies to other protocols such as IGMP.

In the main function of the PON multicast function unit 350, when the identification / distribution is processed for each wavelength of 10 Gbit / s / λ and 2.5 Gbit / s / λ, respectively, 10 Gbit / s / λ and 2.5 Gbit / s, respectively. If stream processing of / λ or more processes multiple wavelengths, multiple wavelengths are required. Further, in the main function of the PON multicast function unit 350, the zapping performance (JOIN latency) is required to comply with the provisions such as 1.5 seconds or less on average as packet processing.

As an example of function sharing, the identification and distribution of multicast (MC) streams can be processed by software if it is a CPU with high-speed processing capability, but hardware + composite is desirable. In addition, since the frequency and delay restrictions of the application system and ONU settings for uplink are loose, they are processed by the application.

FIG. 18 is a diagram showing an example of the functional configuration of the power saving control function unit 360. As a process constituting the function of the power saving control function unit 360, it has a sleep proxy / traffic monitor, an ONU wavelength setting, and an inter-wavelength setting transition. Even if these processes are composed of basic processes such as L3 packet processing (preferably provided with IPv6 Parse), L3 packet generation, table management, OSU power saving state diagram (SD: State Diagram), and communication with OMCI function. Good. For sleep proxy / traffic monitor, ONU wavelength setting, and inter-wavelength setting transition, the same processing may be realized by a combination of basic processing.

As an example of function sharing, a power save (PS: Power Save) application or, depending on the signal, proxy processing can also be processed by the application. Power saving control State transition management (driver part) requires speed, but it can also be processed by the application. The traffic monitor can be processed by the application only for the config (config).

FIG. 19 is a diagram showing an example of a functional configuration of the frequency / time synchronization function unit 370. The OLT subordinately synchronizes its real-time clock (RTC) to a higher-level device by using SyncE (Synchronous Ethernet®) (for frequency synchronization) and IEEE 1588v2 (time synchronization). Further, OMCI is used to notify the ONU of the correspondence between the PON super frame counter (SFC) and the absolute time (ToD: Time of Day) information. These processes may consist of holding a real-time clock, which is a basic process. Equivalent processing may be realized by a combination of basic processing. Moreover, the order may be changed.

In this main function, frequency synchronization accuracy +/- 50 ppb (LTE FDD, TDD), time synchronization accuracy +/- 1 to 1.5 microseconds (LTE TDD, small cell), +/- 1 microseconds (G.I. It is required to comply with the provisions such as 987.3). As an example of the division of functions, the real-time clock itself is the device-dependent unit 110, and the time adjustment calculation to the higher-level device can be processed by the application (it can also be the device-dependent unit 110 depending on the accuracy).

FIG. 20 is a diagram showing an example of a functional configuration of the protection function unit 380. Redundant switching (CT, SW, NNI, CONT, PON (Type A, B, C)) is provided as a process that constitutes the protection function of the protection function unit 380. These processes may be composed of basic processes such as redundant path setting, switching trigger detection, switching notification transmission / reception, and switching processing. Equivalent processing may be realized by a combination of basic processing. Moreover, the order may be changed.

In this main function, forced switching is required to comply with regulations such as 50 milliseconds or less. As an example of function sharing, processing by the application can be performed except for hardware switching trigger detection and switching processing such as failure detection. If the EMS side is instructed (from) when the switching trigger is detected without setting the redundant path in advance, it depends on the device.

The eight main functions may be provided as needed. For example, only the PON main signal processing function, the PON access control function, the L2 main signal processing function, and the maintenance operation function may be provided, or other functions may be provided. You may. In addition, the evaluation of whether or not each function can be made into software is an example on the premise that the processing capacity of the OLT expected in 2018 and the application of the soft switch are not assumed. It may be changed as appropriate assuming the assumed processing capacity and application of the soft switch. The function may or may not be softened. The internal configuration of each function may be another configuration as long as the same function can be realized.

The main softening area is the algorithm included in the eight main functions. The function used as the software area is the device-independent application unit 130 on the device-independent APIs 21 and 22. For example, the algorithms in the ONU registration or authentication function, the DWBA function, the setting / management / monitoring control function, and the power saving control function that contribute to the differentiation service are treated as the extension function unit 131 in the device-independent application unit 130. The MLD proxy app includes a multicast function.

The extended function unit 131 is used as the extended function unit 131 according to the importance such as the frequency of updating functions and the realization of original specifications in the application. Those with low update frequency or low demand for realization of original specifications are middleware section 120 other than basic function section 132 and device-independent application section 130, device-dependent software, hardware section 111 (PHY), and hardware section 112 ( MAC) is preferable. In particular, it is preferable to leave the limited functions due to the processing capacity of the software as the hardware unit 111 (PHY) and the hardware unit 112 (MAC). For example, priority processing of main signals and functions such as DBA that improve line utilization efficiency or contribute to service differentiation, and management that is closely related to the operator's business flow and requires unique specifications for each operator. From the control function to the extended function unit 131.

FIG. 21 is a diagram showing a detailed example of the architecture of the communication device. The embedded OAM engine 114a (Embedded OAM Engine) is connected to the DBA application unit and the protection application unit via the middleware unit 120. The PLOAM engine 114b is connected to the DWBA application, ONU registration authentication, high-speed monitoring application, power saving application, and protection application via the middleware unit 120.

The OMCI is connected to the power saving application and the low speed monitoring application (OMCI) via the middleware unit 120. The L2 function unit (L2 function) is connected to the power saving application and the MLD proxy application via the middleware unit 120. The L2 function unit is further connected to the setting / management application via the middleware unit 120. The NE management unit 115a is connected to the setting / management application. The NE control 115b is connected to a low speed monitoring application (EMS-IF).

FIG. 22 is a diagram showing a flow of signals / information between functional units in a communication device. The figure shows the flow of signals / information between functional units in a communication device, focusing on In / Out of OLT. As shown in the figure, the OLT as a communication device is composed of an API lower processing entity (FASA platform) and an application (FASA application).

The API lower processing entity is the MPCP / DBA processing entity whose OLT input / output target is a transmission instruction and reception notification for MPCP transmission / reception, the OAM processing entity whose OLT input / output target is OAM transmission / reception, and the OLT input / output target is ONU authentication transmission / reception. A certain ONU authentication processing entity, an MLD / IGMP processing entity whose OLT input / output target is MLD / IGMP transmission / reception, another protocol processing entity whose OLT input / output target is other protocol transmission / reception, and main signal processing such as bridge / encryption for OLT input / output It is illustrated by the main signal setting processing entity which is the setting and reference / state acquisition for, and the device management processing entity whose OLT input / output target is OLT hardware, IF, OS, or the like. Here, it is desirable that the transmission instruction and reception notification for MPCP transmission / reception are something like send_frame (* raw_frame); assuming that the driver is directly hit.
In the figure, DBA, ONU management, line management, multicast, EtherOAM, redundancy, device management, alarm management, Netconf agent, and application management are illustrated as applications.

In / Out of OLT is roughly classified into three types: input / output to ONU, setting / notification to OLT itself, and input / output to and from EMS. Seen from the application on the upper side of the API, the lower processing part of the API is (a) easier (conveniently) and (b) common (between multiple types) than the processing such as direct tapping of the driver. , (C) It is desirable that there is a processing entity that conveniently processes it.

The functional division of the API lower processing entity is illustrated below. The app has a corresponding process. The functional division between the API lower processing entity and the application may be any of the following or other than that, and may differ depending on the actual processing.

(0) Message through: A message is passed through the upper side of the API and the ONU / upper NW.

(1) Framing: The message is unframed, decomposed or processed into elements as necessary, and provided to the upper side of the API. Information is passed from the upper part of the API to the lower part of the API. The API lower processing entity performs framing. Since the API is highly dependent on each protocol, it may be included in the device-dependent application section. It is desirable that fixed parameters (type values, etc.) are set and retained from the top of the API at the time of initialization. The setting parameter returns to the reference from the top of the API.

(2) Automatic response: The processing entity is responsible for sending and receiving messages that do not require judgment, such as periodic transmission and fixed response. It is desirable that the operation is set in advance from the upper part of the API. For example, response cycle. Notify the result only when notification to the upper part of API is required.

(3) Autonomous judgment: The processing entity is also responsible for processing that involves judgment. Policy settings are made in advance from the top of the API.

This figure is described in accordance with IEEE-compliant 10GEPON, but the same applies to ITU-T and other compliant devices if the corresponding functions and processes are read. In addition, the functions and processing conditions are examples, and may be added, deleted, replaced, or changed as appropriate according to the conditions.

FIG. 23 is a diagram showing an example of an application executed by the communication device. CPU processing is classified into three groups. The three groups are a CPU for Cont, a CPU for OSU, and a CPU for SW. The CPU processing for Cont is a process of executing a low-speed monitoring application (OMCI), a low-speed monitoring application (EMS-IF), and a setting / management application. The processing of the CPU for SW is the processing of executing the MLD proxy application. The processing of the CPU suitable for OSU is a process of executing a power saving application, a protection application, a high-speed monitoring application, a DBA application, a DWBA application, and an ONU registration authentication application. The device setting IF may be a part of the EMS-IF and may be equivalent to the device-dependent API 25.

This is an example in which each application is processed by the CPU on the CPU package. In FIG. 23, each application is oriented toward a control package (Cont. In FIG. 23) which is a control unit in the OLT, and is oriented toward an OSU package (OSU in FIG. 23) having a plurality of optical transmitters / receivers (λCard in FIG. 23), OSU, and It is classified into 3 groups suitable for SW packages that input / output data to / from the devices on the upper network side. The OSU group is a power saving application, protection application, high-speed monitoring application, DBA application, DWBA application, ONU registration authentication application, the SW group is an MLD proxy application, and the Cont group is a low-speed monitoring application (OMCI) and low-speed monitoring application (EMS-). IF), a setting management application. Further, although centralized control by the CPU is assumed, the applications of each classified group may be distributed and arranged in each package (Cont, OSU, SW). Further, regardless of the above classification, it may be arranged on any one of Cont, OSU, SW, or a plurality of combinations thereof. Further, the device setting IF in FIG. 23 may be a part of the EMS-IF, or may be equivalent to the device-dependent API 25 in FIG. Further, although the processing of the application is performed on the CPU, some or all of the processing may be performed on an alternative device having a processing function, for example, a processor other than the CPU, such as a GPU, NPU, DSP, or an FPGA. The same applies to other embodiments.

FIG. 24 is an example in which the application is arranged on a server or the like instead of the CPU package. The application is processed on a server or the like, and the processing result of the application arrives at the OLT after being transmitted on the transmission line in a format that can be transmitted on the transmission line such as an Ethernet (registered trademark) frame. Here, as the format that can be transmitted on the transmission line, a frame other than the Ethernet (registered trademark) frame or transmission of TDM or the like may be used. Further, the processing result is transmitted via a converter (Conv. In FIG. 24), but if the OSU, SW, or λ card can receive the processing result of the application without going through the converter, the conversion is performed. No machine is needed. The server or the like may correspond to the external server 16 of FIG. 8 or the proxy unit 15.

FIG. 25 is a diagram showing an example of functions (processing) of the CPU, the switch unit (SW), and the OSU. The CPU executes the power saving control function and the protection function by the application. The CPU further includes a maintenance operation function (Fault Management), a maintenance operation function (GTC / PMD configuration), a PON access processing function (ONU activation), a PON access processing function (DBA), and a PON access processing function (λ). (Assignment change), maintenance operation function (Service Management), and maintenance operation function (Equipment Management) are executed. Furthermore, the CPU further executes the maintenance operation function (Fault Performance Management) and the multicast function (MLD) by the application.

The switch (SW) includes an L2 signal processing function (VLAN), an L2 signal processing function (QoS, Quality of Service), an L2 signal processing function (Mux / DMux, XC, Cross Connect), and a multicast function (Copy). Is executed by the application. The OSU MAC executes a PON main signal processing function (Security), a PON main signal processing function (Framing), a PON main signal processing function (FEC), and a frequency / time synchronization function by an application.

In FIG. 25, the CPU enclosure shows an example of processing by the basic function unit 132 and the original function, and the OSU MAC shows an example of processing in the vendor-dependent part, but the classification is not limited to this. The CPU of FIG. 25 may be a CPU package of FIG. 24, a location having processing capacity other than that of the server of FIG. 24, or a combination thereof. The MAC of the OSU assumes a dedicated LSI for OSU processing, but a general-purpose LSI may be used as long as equivalent processing is possible.

FIG. 26 shows the processing of the application of the eight main functions and G.I. It is a figure which shows the example of correspondence with 989.3 function. The DBA application, the DWBA application, the ONU registration authentication application, the power saving application, the protection, and the high-speed monitoring application are connected to the TWDM TC function unit (TWDM TC artifacts) of the TWDM TC layer. The MLD proxy is connected to the L2 function unit (L2 function). The L2 functional unit is connected to a user data client (User Data Client). The setting / management application, the low-speed monitoring application (OMCI), and the low-speed monitoring application (OSS-IF) are connected to the L2 function unit (L2 function). The setting / management application, the low-speed monitoring application (OMCI), and the low-speed monitoring application (OSS-IF) are further connected to the OMCI client.

FIG. 27 is a diagram showing an example of a configuration in which PLOAM and OMCI are acquired via SW. That is, FIG. 27 shows a process in which PLOAM and OMCI acquire the corresponding data from the control unit 14 or the proxy unit 15 of FIG. 8 or the external server 16 via the SW in addition to the user data.

The user data client (User Data Client) acquires data from the user data adapter (User Data Adapter) via the switch unit (SW). The user data client sends data to the user data adapter via the switch section. The OMCI client (OMCI Client) of the CPU acquires data from the OMCI adapter (OMCI Adapter) via the switch unit. The OMCI client transmits data to the OMCI adapter via the switch unit.

The PLOAM processor of the CPU acquires data from the "AMCC PHY adaptation framing" (AMCC PHY adaptation And framing) via the switch unit. The PLOAM processor of the CPU transmits data to the "AMCC PHY adaptation framing unit" via the switch unit. Further, the PLOAM processor of the CPU acquires data from the PLOAM partition section (PLOAM partition) via the switch section. The PLOAM processor of the CPU transmits data to the PLOAM partition unit via the switch unit.

The TWDM TC function unit (TWDM TC functions) of the TWDM TC layer acquires data from the embedded header area (embedded header fields) via the switch unit. The TWDM TC function unit of the TWDM TC layer transmits data to the embedded header area via the switch unit.

In the examples of FIGS. 3 and 4, the softened area is the basic function unit 132, the management / control agent unit 133, the extended function unit 131, and the middleware unit 120, but the softened area is the service adaptation (encryption). , Fragment processing, GEM framing / XGEM framing, PHY adaptation FEC, scrambling, synchronous block generation / extraction, GTC (GPON Forward Convergences) framing, PHY framing, SP conversion, and coding method may also be targeted. An example of implementing the software function of the architecture and an example of function deployment corresponding to the hardware section 111 (PHY) and the hardware section 112 (MAC) will be described. The function deployment is softened to, for example, a network device or an external server. It has a function.

Assume an OLT including a plurality of OSUs, switches, information processing units, and control units. Each OSU has a different transmitter / receiver for each wavelength. In this case, the middleware unit 120 is mounted on each OSU and the switch, and the software area such as the device-independent application unit 130 is mounted on the information processing unit.

The information processing unit, that is, the CPU executes the device-independent application unit 130. The device-independent application unit 130 includes an extended function unit 131 for the OSU, an extended function unit 131 for the switch, and an extended function unit 131 for the control unit. The extended function unit 131 for the OSU is, for example, a power saving application, a protection application, a DBA application, and an ONU registration authentication application. The extension function unit 131 for the switch is, for example, an MLD proxy application. The extension function unit 131 for the control unit is, for example, a low-speed monitoring application (OMCI), a low-speed monitoring application (EMS-IF), and a setting / management application. The EMS is, for example, an OSS (Operation Support System).

G. In the case of 989.3, for example, as shown in FIGS. 21, 23 to 25. In the case of the DBA application, the middleware unit 120 shown in FIGS. 3 and 4 or the basic function unit 132 shown in FIGS. 5 and 6 is embedded which is the hardware unit 111 (PHY) and the hardware unit 112 (MAC) of the TC layer. Operate the OAM engine (Embedded OAM Engine). Then, the transmission / reception unit, which is the hardware unit 111 (PHY) and the hardware unit 112 (MAC) of the PMD layer, receives the data according to the DBA application. If the transmitter / receiver receives an uplink signal that does not follow the DBA, it may not follow the DBA application.

The information processing unit is not limited to these softening functions, and may have other softening functions. The hardware unit 111 (PHY) and the hardware unit 112 (MAC) are not limited to the transmission / reception unit, the OSU, the switch, the control unit, and the information processing unit. For example, the information processing unit may be included in the transmission / reception unit, the OSU, the switch, and the control unit. Further, as shown in FIG. 8, a proxy unit or an external server that processes signals input / output to / from the switch may be provided on the NNI (Network-Network Interface) side of the switch. The external server 16 may be an information processing function called a so-called cloud such as a data center provided with a plurality of devices.

Each function may be appropriately arranged according to the demand for processing capacity and processing delay. Further, the OSU may be provided with a switch unit 12 or a switch unit 13, or may be provided with a switch (switch unit 12 when the switch unit 13 is provided) separately from the switch. It is desirable that the functions of the switch are appropriately shared between the switch unit 12 and the switch unit 13 according to the processing capacity of the switch without overlapping, but they may overlap.

The place where the software function is deployed is not limited to the information processing unit, and may be placed in a place where a plurality of arithmetic operations can be performed. For example, the places where the software function is deployed are other than the transmission / reception unit, the OSU switch, the OSU switch, the OLT control unit, the OLT switch, the OLT information processing unit, the OLT switch, the control unit, and the information processing unit. It may be either a proxy unit that processes signals input / output to / from the switch on the NNI side of the switch, or a processing device such as an external server.

Further, the arrangement of the softening functions may be for each softening function, or may be a part of the softening functions obtained by dividing a single softening function. For example, the parts related to the transmission / reception unit are other than the transmission / reception unit, for example, the OSU switch, the OSU transmission / reception unit and other than the switch, the OLT switch, the OLT control unit, the OLT information processing unit, and the rest of the OLT. It may be deployed somewhere outside the OLT, such as a proxy unit or an external server on the main signal path, or a combination of a plurality of deployment locations. Other than the PON termination processing deployment location, for example, OSU transmission / reception unit, OSU switch, OSU transmission / reception unit and other than the switch, OLT switch, OLT control unit, OLT information processing unit , Other than the OLT, it may be deployed to somewhere such as a proxy unit, an external server, etc. on the main signal path outside the OLT, or to a combination of a plurality of deployment locations.

Items related to ONU switches other than ONU switches, such as transmitter / receiver, OSU transmitter / receiver and other than switches, OLT switch, OLT control unit, OLT information processing unit, OLT other than OLT It may be deployed to somewhere such as a proxy unit or an external server on the main signal path outside of the above, or to a combination of a plurality of deployment locations. Other than the OLT switch, for example, the transmitter / receiver, the OSU switch, the OSU transmitter / receiver and other than the switch, the OLT control unit, the OLT information processing unit, the other OLT, the OLT. It may be deployed to somewhere such as a proxy unit, an external server, etc. on the main signal path outside of the above, or to a combination of a plurality of deployment locations.

Further, the location where the software function is deployed may be appropriately changed according to the deployment status of the extension function unit 131, the computing capacity of the computing location, the computing load, the power consumption, and the like.

The main functions related to the main signal processing of the OLT and the relationships between the functions will be described. Transfer the OLT function to the switch. A PON main signal processing function that performs PON section processing such as a PHY adaptation function, a framing function, and a service adaptation function is provided in the transmission / reception unit. PON access control functions such as ONU registration or authentication function, DBA control function, and DWA function are provided in the information processing unit. The switch is provided with L2 main signal processing functions such as VLAN control used in framing, priority control in the pre-stage of shaper, max or demax (Mux / DMux) and queue (Queue), and shaper in the pre-stage of framing.

Deploy the multicast function such as the copy function in the previous stage of the shaper and the MLD proxy used for copying to the switch. In this way, by deploying the PON main signal processing function and the PON access control function deployed in the PON to the switch, the PON basic function unit is reduced. In particular, it is preferable to avoid duplication of the L2 main signal processing and deploy it in the switch.

It should be noted that the switch functions are illustrated on the premise that Classifier (classifier), Modifier (modifier), Policer / Shaper (poliser / shaper), CrossConnect (cross connect), Queue (queue), and Scheduler (scheduler) are provided in this order. However, it may be changed as appropriate. For example, if it is in the uplink direction and processing is not performed within the bandwidth allocation unit, the input from the ONU is PON by removing the preamble and burst overhead for burst transmission, decapsulating the frame, and removing the LLID. All the functions of Classifier, Modifier, Policer / Shiper, Cross Connect, Queue, and Scheduler may be performed by the switch, or only Modifier, Cross Connect, Queue, and Scheduler may be performed by the switch.

Further, if a VID or the like describing the path or the like after the PON termination is given by the ONU, Cross Connect, Queue, or Scheduler may be used. If the upper network can be regarded as a single path, Queue and Scheduler may be used. Further, if the DBA is performed so that the frames do not collide with the Cross Connect, the frame can be a Classifier, a Modifier, a Policer / Shaper, or a CrossConnect. Furthermore, if processing is not performed in the bandwidth allocation unit in the upstream direction, the input from the ONU is removed from the preamble and burst overhead for burst transmission, the frame is decapsulated, and the LLID is removed to PON. If only the termination is performed and a VID or the like describing the path or the like after the PON termination is given by the ONU, only the Cross Connect can be used.

Further, in Classifier, Modifier, Policer / Sharper, CrossConnect, Queue, and Scheduler, Classifer, Policer / Shaper, Modifier, CrossConnect, Queue, and Queue may be placed in front of the quer. It may be a Modifier, Queue, Policer / Sharper, CrossConnect, Scheduler, or it may be a Classiffier, Queuee, Policeer / Queue, Modifier, CrossConnect, Scheduler. Considering the burst transmission of PON, unnecessary police / shaping due to the burst property caused by multiplexing priority traffic such as multicast, and the reception of leveled traffic on the receiving side, the police / shaper It is desirable to execute the processing by Police / Shaping after placing a Queue in the previous stage and leveling it.

At the time of state transition to a specific state, the subject of the sleep operation or the like stores the instruction of the subject of the sleep operation or the like (the device provided in the communication device) in an external state independent of the subject of the sleep operation or the like. It is possible to inherit the operation. The specific state is, for example, a sleep state, a switching state of an operating communication device, a user accommodation switching state, and a multicast state. Since the information is held outside the communication device, it is possible to prevent the inheritance of the sleep operation and the like from being lost when switching to another communication device. The communication device can ensure the inheritance of the information held by the device.

Further, by diverting a normal general-purpose or softwareized switch as an execution unit, it is possible to realize an OLT capable of inexpensive, flexible and quick function addition of a general-purpose or softwareized switch.

The configuration according to the first embodiment shown above is the same in the following embodiments, and may be appropriately combined. For example, FIG. 3 illustrates a case where the execution unit is composed of only the transmission / reception unit 11 (TRx), the switch unit 12 and the switch unit 13, but the transmission / reception unit 11 (TRx), the switch unit 12 and the switch unit A place other than 13, a place other than that, a place where the PON is terminated, or a control unit 14 may be an execution unit.

Is.

(Embodiment 1-3)
Although the configuration used for TWDM-PON is illustrated in the first embodiment, it may be applied to WDM-PON. The embodiment 1-3 is the embodiment 1-1, except that the WDM-PON does not have to have a function of time-dividing and multiplexing the band resources of the PON section of the ONU-OLT between ONUs such as DBA. Is similar to.

(Embodiment 1-4)
The present embodiment is a combination including OFDM (Orthogonal Frequency Division Multiplex) -PON, CDM (Code Division Multiplex) -PON, SCM (Subcarrier Multiplex) -PON, and core wire division multiplexing.

Although the configuration used for TWDM-PON is illustrated in the first embodiment, it may be applied to a PON that shares resources other than wavelength and time. For example, it may be applied to OFDM-PON that divides and multiplexes the frequency resource of electricity of one wavelength, SCM-PON that divides and multiplexes the frequency resource of electricity of one wavelength, CDM-PON that divides and multiplexes by a code, or core wire division. Multiplexing may be used in combination, space division multiplexing using a multi-core fiber or the like may be used in combination, or wavelength division multiplexing may not be used. The same applies if the function of dividing and multiplexing the wavelength resources of the TWDM-PON by wavelength division multiplexing is read as a function corresponding to the function required for dividing and multiplexing each of the multiplexed resources.

(Embodiment 2)
In the second embodiment, the configuration used for TWDM-PON performs GEM encapsulation. In this case, the switch is provided with an adapter that generates a GEM frame so that the GEM frame is conducted between the switch and other parts. By transferring the GEM encapsulation to the switch, the L2 functional part can be excluded from the protocol stack of the other part, and the overlap of the L2 functional part can be avoided in the switch and the other part.

Although TWDM-PON is taken as an example, if the frame for identification in the PON section is handled in the same manner as in the first to second embodiments to the first to fourth embodiments, the same applies to other PONs. The effect of is obtained. For example, in the case of IEEE standard GE-PON, 10GE-PON, etc., instead of the GEM frame, an LLID may be added so that the frame to which the LLID is given conducts between the switch and other parts. Good.

(Embodiment 3)
In the third embodiment, the control information used for the TWDM-PON goes through the switch. In this case, instead of transferring the bridge function-related to the switch, any one of PLOAM, Embedded OAM, and OMCI that retains control information is framed as necessary and processed via the switch. By inputting and outputting control information via the switch, there is an effect that processing other than the switch becomes lighter. In addition to the transfer of the third embodiment, the transfer of the bridge function of the first and second embodiments may be performed.

Although TWDM-PON is taken as an example, if the control information is handled in the same manner and processed via the switch, the same applies to other PONs as in the first to second embodiments to the first to fourth embodiments. The effect is obtained.
