Abstract

PURPOSE:To attain effective management by allowing a circuit network constitution managing device to decide the new assignment of a device address when the device connected to a circuit network entry device is changed, and informing it to each entry device to change the content of the table. CONSTITUTION:The circuit network constitution managing device 10 and circuit network entry devices 301-30n are connected via a communication circuit network 20. When a device A connected newly to, e.g., the device 301 is confirmed uniquely for the address on the circuit network by the device 10 and the result is informed to the entire devices 301-30n. Then a device B connected to, e.g., the device 30n can communicate with the device A without notifying the address on the circuit network.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a method for automating the configuration management of a communication network.

[Background of the invention]

Conventionally, there is a method for managing the configuration of a communication network.For example, as disclosed in Japanese Patent Application Laid-Open No. 55-32140, one center manages the addresses of all devices in the network, When communicating with a device, there is a known method in which the address is always confirmed at the center before communication is made. However, when communicating with this method,
Since the data always goes through a center, there is a problem in that if the center goes down, the entire network system goes down.

[Purpose of the invention]

The present invention has been made in order to eliminate the problems of the above-mentioned conventional methods, and it is an object of the present invention to provide a network configuration management method that enables direct communication between arbitrary devices connected to a network.

[Summary of the invention]

The present invention provides a network system that includes a network configuration management device that centrally manages the configuration of a network and a network entry device that accommodates one or more devices that communicate via the network. When adding, the network configuration management device determines the address of the new device.

By registering that address and new device name to all network entry devices in the network, the devices connected to the network entry device will not be aware of the address.

It allows communication with any device.

[Embodiments of the invention] FIG. 1 shows the overall configuration of an embodiment of the present invention.

In FIG. 1, a network (communication network) 20 includes a network configuration management device IO and a number of network entry devices 30. ~307. are connected, and a device 40 is connected to each network entry device. The network configuration management device 10 includes a communication device 11 that communicates with other network entry devices, and a processing device that processes data received via the communication device 11! 12, an address determining device 13 that assigns a network address to a new device, and a memory device 114 that stores a table that stores network addresses corresponding to each device.
Consisting of Network entry devices 301-30. ,
are Tsushin@31 and 1, which communicate with other network entry devices or network configuration management devices 10, respectively.
Data sent and received via communication device 31 and device 4
A processing device 32 that processes the connection/removal notification of 0, and a connection control device that controls the device 40 connected to the entry device! 33, and a memory device 3 that stores a table that stores network addresses corresponding to each device.
Consists of 4.

The present invention provides a network configuration management device 10, a network entry device 30. .about.30n are connected via the communication network 20, for example, the network entry device 30. From then on, the network configuration management device 10 uniquely determines the network address of the newly connected device A, and notifies all the network entry devices 30 to 3On.

For example, device B connected to network entry device 30rl can communicate with device A without being aware of the address on the network. This will be explained below with reference to FIG.

Network entry device 30. When device A is newly connected to the connection control device 33 of , sends a network address confirmation request command 201 for device A. Network configuration management device 1
0 processing bag [12 checks the command received via the communication device 1fll, requests the address determination device 13 to determine the network address corresponding to device A, and stores the determined network address α in the memory device Wi14. It is stored in the table 141. at the same time.

The processing device 12 sends the message 202 regarding the address α of the newly added device A to all network entry devices 30. ~30. ．． to notify.

Entry equipment W30. receives the message via Tsushin W31 and stores the network address α of device A in the reserved entry of table 341. Similarly,
The entry device 30n uses the processing device 32 to store the memory device 34 in response to the message received via the communication device 31.
An area is secured on the table 341 to store device A and its network address α. Note that the processing device 32 of the entry device 30n makes a desired determination.

It is also possible to determine whether storage is necessary.

As described above, device B connected to the network entry device 30° can access the entry device 3o by simply specifying the device name A without knowing the network address of device A.

The processing unit 32 detects the network address of device A from the memory device 34, and automatically stores the entry 6, 30., where device A exists via the communication device 31. This means that the message 203 can be sent to.

In addition, even if, for example, device B that has been on the network is to be disconnected from entry device 3on, it is possible to notify all 5 entry devices of this via the same route, and automatically The network configuration is uniquely determined.

〔Effect of the invention"〕

According to the present invention, it is expected that the following effects can be obtained.

(1) By providing the network configuration management device and the network entry device with an information exchange table regarding configuration changes of devices connected to the entry device, it becomes possible to uniquely define the network configuration.

(2) By automatically adding entry information on each entry device, it becomes possible to dynamically change device configuration information even while other online systems are in operation.

(3) By being able to dynamically change configuration information, false rumors can be avoided.
No matter where the device is connected to the network entry device, it will be able to communicate with other devices.

Claims (1)

[Claims] (1) A network configuration management device that centrally manages the network configuration and multiple network entry devices each accommodating one or more devices that communicate via the network are connected to the network, and each device is uniquely assigned. In a communication network system that performs communication between arbitrary devices by sending and receiving assigned addresses, each network entry device has a table showing the correspondence between all devices existing in the network and their addresses, and is connected to the network entry device. When a device is changed, the network configuration management device decides to allocate or delete the address of the device in response to a request from the network entry device, and notifies all network entry devices.In response, each network entry device is a network configuration management method characterized by changing the contents of its own table.
