Description
Technical Field
The present disclosure relates to the field of internet technologies, and in particular, to a method and an apparatus for issuing a route, and a network device.
Background
The routing table is used for storing routing information pointing to the network device, and when the switch forwards the data message, the switch needs to obtain a next hop network address and information such as a physical outgoing interface for forwarding the data message by querying the routing table, and forwards the data message to the next hop network device through the found outgoing interface. When a user changes networking configuration or a link changes, the switch needs to send new routing information to a routing table of the switch chip. Because the number of network devices in the network is large and the change is frequent, the switch needs to issue a large amount of routing information. Currently, the routing specification on a switch can reach the order of mega, depending on the specification of the hardware routing table.
Because the service board of the switch generally includes one or more switching chips, when a route in the routing table is added, deleted or modified, the route needs to be issued once per switching chip according to an interface provided by a chip manufacturer.
For a switch supporting MDC (multi tenant Device Context) configuration, the switch may be divided into multiple MDC devices through virtualization technology. Because different exchange chips on the single board can be divided into the same MDC equipment, the route issuing under the MDC environment is also issued according to the chip, and each exchange chip is issued once.
Because the routing table is generally a tree-structured soft table, and each switching chip has its own routing table, when the service board CPU issues a new route to the switching chip, each interaction chip needs to calculate the position of the new route in the routing table through software first, and then the CPU issues the route to the corresponding position. The larger the number of switching chips, the longer it takes to issue routes. Similarly, for the MDC environment, the more chips that are divided into the same MDC on the same board, the lower the corresponding route delivery efficiency.
For the switch with a large number of routes, if a user changes the networking configuration or a link changes, the routes on the switch are added, deleted or modified, so that if the routing issuing efficiency of the switch is low, the message sent by the user cannot reach the destination device for a long time, and even serious packet loss occurs when the routes are changed.

Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the embodiments of the present disclosure will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only a part of the embodiments of the present disclosure, but not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
The embodiment of the disclosure provides a route issuing method, a device, a network device and a machine readable storage medium, aiming at the problem that the existing route issuing method has low route issuing efficiency in a multi-chip environment. The technology can be universally applied to network equipment such as a switch, a user gateway or a router, and the network equipment can comprise a main control board and a service board. The main control board is generally only responsible for the calculation of various network protocols, does not participate in the forwarding of service messages, and generally requires high CPU performance and a relatively large memory. The service board is mainly responsible for forwarding service messages, one or more switching chips connected with the service board CPU are arranged on the service board, and a routing table containing a large amount of routing information is stored in each switching chip. The types of the plurality of switching chips can be the same or different, but the routing tables of each switching chip are globally consistent, wherein the global consistency comprises that the storage modes of the routing tables of the switching chips are the same, and the table entry positions of the same routing information in the routing tables are the same.
The network device may also support MDC configuration, where the MDC configuration may divide a network device into multiple logical devices through a virtualization technology, and each logical device is referred to as an MDC device. Each MDC device has own exclusive software and hardware resources, operates independently, forwards independently and provides services independently. If one MDC device is created, started, restarted and deleted, the operation of other MDC devices is not influenced. Each MDC device is a separate physical device for the user. The MDC devices are isolated from each other, cannot communicate directly, and have high security. For the manager, when a new branch office is added, the expense for purchasing new network equipment and upgrading the network equipment hardware can be saved by dividing the MDC, and the utilization rate of the existing network resources is improved. Meanwhile, a plurality of MDC devices are integrated on one physical device, so that the management and maintenance cost can be effectively reduced.
The following describes in detail a route issuing method, an apparatus, a network device, and a machine-readable storage medium according to the present disclosure by using specific embodiments.
The first embodiment is as follows:
this embodiment provides a route issuing method, which is applied to the above network device, where the network device includes at least a processor and multiple switch chips connected to the processor, and the multiple switch chips belong to one MDC device, so that routing tables in the multiple switch chips can be globally consistent. The service boards of multiple switching chips can be regarded as belonging to the same MDC device.
As shown in fig. 1, the flow chart of the route issuing method includes the following steps:
step S101, if the processor has routing information to be issued, selecting a target switching chip from a plurality of switching chips.
When applied to different network environments, the processor may be a service board CPU or a processor of an MDC device, and will be described in two cases.
One situation is: a plurality of switching chips belong to the same service board, and each switching chip is connected with a service board CPU. If the service board CPU receives a remote-end route operation request or learns a new remote-end route, one switching chip can be arbitrarily selected from a plurality of switching chips to be used as a target switching chip; the first exchange chip of the service board or the default exchange chip of the system can also be used as the target exchange chip, and the mode can avoid that the target exchange chip is determined again when the route is issued every time, thereby saving the program.
The other situation is as follows: for a network device supporting MDC configuration, multiple switching chips belong to the same MDC device. When the MDC is created, the main control board CPU and the service board CPU create corresponding task processes in the processor of the MDC device, and each time an MDC device is created, a related task process is created, and the task processes between different MDC devices are independent from each other. If a routing Protocol such as Open Shortest Path First (OSPF), Border Gateway Protocol (BGP), etc. is enabled on a port of a certain MDC device, when a new remote route is learned, a forwarding task corresponding to a main control board CPU synchronizes a routing message to a forwarding task corresponding to a service board CPU. The forwarding task corresponding to the service board CPU sends the current routing message to the driving module, and the driving module analyzes the routing message to obtain a KEY (keyword) of the route: DIP (destination IP address) and the result of the lookup, next hop, etc.
After the routing information is obtained through analysis, the processor of the MDC device needs to issue the routing information to the routing table of each switching chip for storage. At this time, the processor of the MDC device may arbitrarily select one switching chip from the plurality of switching chips as a target switching chip; the first switching chip of the MDC device or the system default switching chip may also be used as the target switching chip.
And step S102, sending the routing information to a target exchange chip.
Specifically, the processor of the service board CPU or the MDC device issues the routing information to the target switching chip, so that the target switching chip calculates the entry position of the routing information in the routing table according to a set algorithm. The set algorithm may adopt a conventional calculation method. For example, the branch to which the routing information belongs in the routing table is calculated from the prefix of the DIP.
Step S103, receiving the table entry position of the routing information in the routing table determined by the target exchange chip.
Step S104, the table position and the routing information are sent to a plurality of exchange chips.
After receiving the table entry position of the routing information in the routing table returned by the target switching chip, the service board CPU or the processor of the MDC device issues the table entry position and the routing information to the plurality of switching chips in a broadcast manner.
The routing issuing method provided by the embodiment of the disclosure can select only one switching chip to determine the table entry position of the routing information in the routing table when issuing the routing information for a plurality of switching chips belonging to the same MDC device, and issues the routing information to all the switching chips according to the calculation result of the switching chip without calculating each switching chip, thereby reducing the calculation time consuming longer in routing issuing, improving the issuing efficiency of the routing, and effectively reducing the packet loss phenomenon occurring when the routing changes.
Example two:
the present embodiment provides a more preferable route issuing method, which is also applied to a network device including a plurality of switch chips, where the plurality of switch chips are connected to a processor of the network device, and the routing tables in the switch chips are globally consistent. The network device supports a DMA (Direct Memory Access) issuing mode of the route, that is, all the switch chips of the network device support the DMA issuing mode of the route. Referring to the flowchart of the route issuing method shown in fig. 2, the method includes the following steps:
step S201, if the processor has routing information to be issued, a target switching chip is selected from the plurality of switching chips. Similar to the first embodiment, in different network environments, the processor may also be a processor of a service board CPU or an MDC device, and details are not described herein.
Step S202, the routing information is sent to the target exchange chip.
Step S203, receiving the table entry position of the routing information in the routing table determined by the target switch chip.
The processor receives the table entry position of the routing information in the routing table returned by the target switching chip, and stores the table entry position and the routing information into a DMA cache area of the storage chip. Alternatively, the target switch chip stores the entry location and routing information in the DMA cache.
Step S204, judging whether the number of the routing information of the current determined table entry position reaches a preset threshold value; if yes, go to step S205; if not, return to step S201.
Step S205, issue each routing information and the corresponding table entry position to multiple switch chips.
If the table entry positions and the routing information stored in the DMA cache region reach a certain amount, the table entry positions and the routing information stored in the DMA cache region can be directly sent to the routing table of each switching chip in a data broadcasting mode at one time.
As another implementation manner of this embodiment, the processor may first store the routing information to be issued to the DMA buffer of the memory chip or the DMA buffer of the target switch chip. After the routing information in the DMA cache reaches a certain number, the table entry position of each routing information in the routing table is calculated through the target switching chip, and then each routing information and the corresponding table entry position are issued to a plurality of switching chips.
In addition, the step S205 is triggered by counting that the number of the routing information items at the determined table entry positions reaches the preset threshold, as another implementation manner, a time factor may also be introduced, and the step S205 is executed when one of the number of the routing information items at the determined table entry positions meets the preset threshold, and the time factor is monitored whether the time length from the occurrence of the first routing information to the current time reaches the set time length, and whether the number of the routing information items at the determined table entry positions reaches the preset threshold, so as to ensure the timeliness of routing delivery.
Compared with the existing way of issuing the route by using the DMA, the route issuing method provided by the embodiment of the present disclosure may be implemented by storing the route information and the table entry position to be issued in the DMA buffer area by the processor, and writing the route information stored in the buffer area into the route table once after reaching a certain number, so as to improve the route issuing efficiency of a single chip service board supporting the DMA issue. Therefore, under the multi-chip environment, the calculation amount of software is reduced, the calculation speed is improved, the frequency of frequently accessing hardware is reduced, the message forwarding rate of the user terminal is further improved, and the user internet experience is improved.
It should be noted that the two method embodiments are described in a progressive manner, each embodiment focuses on the differences from the other embodiments, and the same and similar parts between the embodiments are referred to each other.
Example three:
considering that the application scenario of the route delivery includes route addition, route deletion, route update, and the like, the present embodiment refines the step of delivering the table entry position and the route information to the plurality of switch chips, and includes:
if the routing information is the routing information of the route to be added, respectively writing the routing information into the table entry positions of the routing tables of the plurality of switching chips;
if the routing information is the routing information of the route to be cancelled, respectively searching the table entry positions of the routing tables of the plurality of switching chips, and deleting the routing information in the searched table entry positions;
if the routing information is the routing information of the route to be updated, the table entry positions of the routing tables of the plurality of switching chips are respectively searched, and the routing information is used for replacing the routing information in the searched table entry positions.
Based on this, the present embodiment provides a route issuing method, which takes the example of adding a route to a network device supporting MDC configuration as an example. Referring to the flow chart shown in fig. 3, the method includes the steps of:
step S301, when a new far-end route is learned, the far-end route message is analyzed through the driving module, and route information is obtained.
When the MDC device is created, the main control board CPU and the service board CPU create corresponding task processes in the processor of the MDC device, and each time an MDC device is created, a related task process is created, and task processes between different MDC devices are independent from each other. If a routing protocol such as OSPF, BGP, etc. is enabled on a port of a certain MDC device, when a new remote route is learned through the port, the forwarding task corresponding to the main control board CPU synchronizes the remote route message to the forwarding task corresponding to the service board CPU. The forwarding task corresponding to the service board CPU sends the current far-end routing message to the driving module, and the driving module analyzes the far-end routing message to obtain the KEY of the route: DIP and the result of the search, next hop and other routing information.
Step S302, a switching chip is selected as a target switching chip through the MDC module.
When the MDC device is created, the MDC module records the corresponding relationship between the port and the switch chip in the MDC device according to the information configured by the user. When a new far-end route is learned on a port of a certain MDC device according to a routing protocol, a forwarding module corresponding to a processor or a service board CPU of the MDC device acquires an exchange chip of the MDC device which belongs to the current device recorded by software through an MDC module according to the MDC device which belongs to the current device, and the exchange chip is used as a target exchange chip.
Step S303, the routing information is sent to the target switching chip, so that the target switching chip calculates the table entry position of the routing information in the routing table.
Step S304, the table entry position and the routing information are sent to a plurality of switching chips in a broadcast mode, so that each switching chip adds new routing information to the corresponding table entry position in the routing table.
When the route is issued, all the switching chips contained in the current MDC equipment can be determined through the MDC module, all the switching chips contained in the current MDC equipment are polled, and the route information is broadcasted and issued to the routing tables of all the switching chips in the current MDC equipment according to the table entry position calculated by the target switching chip.
Fig. 3 illustrates a route adding process as an example, and for a similar implementation manner of deleting a route, refer to a flowchart of a route issuing method shown in fig. 4, where the method includes the following steps:
step S401, when the remote route revocation is sensed, the remote route revocation message is analyzed through the driving module, and the route information is obtained.
When a certain port of the MDC device senses the remote route revocation, the forwarding task corresponding to the main control board CPU synchronizes the remote route revocation message to the forwarding task corresponding to the service board CPU. The forwarding task corresponding to the service board CPU sends the current far-end route revocation message to the driving module, and the driving module analyzes the far-end route revocation message to obtain the KEY of the route: DIP and the result of the search, next hop and other routing information.
Step S402, selecting a switch chip as a target switch chip through the MDC module.
When the MDC device is created, the MDC module records the corresponding relationship between the port and the switch chip in the MDC device according to the information configured by the user. Therefore, one switching chip of the MDC device to which the software record currently belongs can be acquired by the MDC module as the target switching chip.
Step S403, sending the routing information to the target switching chip, so that the target switching chip searches for the table entry position of the routing information in the routing table.
Step S404, the table entry position and the routing information are sent to a plurality of switching chips in a broadcasting mode, so that each switching chip deletes the routing information in the routing table.
After receiving the table entry position of the routing information returned by the target switching chip in the routing table, determining all switching chips contained in the current MDC equipment through an MDC module, polling all switching chips contained in the current MDC equipment, and sending the table entry position and the routing information found by the target switching chip to all switching chips in the current MDC equipment in a broadcasting manner, so that each switching chip deletes the routing information in the corresponding table entry position in the routing table.
The implementation mode of updating the route is similar to the implementation mode of deleting the route, and when the change of the far-end route is sensed, the far-end route change message is analyzed through the driving module to obtain the route information needing to be updated. The target exchange chip determines the table entry position of the route in the route table according to the route information required to be updated, and then sends the table entry position and the route information to a plurality of exchange chips in a broadcasting mode, so that each exchange chip can replace the route information of the corresponding table entry position in the route table with new route information.
The route is added, deleted or updated by adopting the route issuing method, and for a plurality of switching chips belonging to the same MDC equipment, when the route information is issued, only one switching chip can be selected to determine the table entry position of the route information in the route table, and the route information is issued to all the switching chips according to the calculation result of the switching chip without calculating each switching chip, so that the calculation time which is long in time consumption in the route issuing is reduced, the route issuing efficiency is improved, the packet loss phenomenon which occurs when the route is changed is effectively reduced, the message forwarding rate of a user terminal is improved, and the user internet experience degree is improved.
