An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. In the figure, a network interface node 2 is installed between the network management system 1 and a network device 3-i (i = 1, 2, ..., N). The network interface node 2 notifies the network management system 1 of the failure detection information from the network device 3-i, and at the same time sends various commands from the network management system 1 to the network device 3-i.
i Tell each to execute various operations.

The network interface node 2 has a communication section 20-i corresponding to each of the network equipment 3-i.
Is provided and controls communication with each of the network devices 3-i by the communication unit 20-i, and constantly sends a polling command to each of the network devices 3-i to constantly connect and communicate with each other. Are watching.

When there is a change from the state in which there is no response to the polling command from the communication unit 20-i to the state in which a response is returned, the communication unit 20-i determines that the network device 3-i is newly connected. , Executes a communication procedure to collect the communication address of the newly connected network device 3-i.

When the communication unit 20-i obtains the physical address of the network device 3-i newly added by executing the above-mentioned communication procedure, the network device 3-i is newly connected and the network device 3-i is connected. The physical address of i is sent to the network management unit 21 as state change information.

On the other hand, when no response is returned to the polling command from the communication unit 20-i, the communication unit 20-i
Determines that the network device 3-i has been removed, and the network management unit 2 uses that as state change information.
Send to 1.

The network management unit 21 is a communication unit 20-i.
The connection status of the network device 3-i is determined according to the status change information from the network connection management information recording unit 2
The network connection configuration management table recorded in 2 is updated.

That is, when the network device 3-i is newly connected, the network management unit 21 stores the network device 3 in the network connection configuration management table corresponding to the physical address of the network device 3-i.
-Add connection information for i.

When the network device 3-i is removed, the network management unit 21 deletes the connection information of the network device 3-i from the network connection configuration management table corresponding to the physical address of the network device 3-i. .

When the network management unit 21 updates the network connection configuration management table, the network device 3
-I notifies the control unit 23 that the connection configuration has changed. When the change of the connection configuration is notified from the network management unit 21, the control unit 23 notifies the network management system 1 of the change of the connection configuration.

The network management system 1 has a control unit 23.
Update the internal database based on the notification from and change the screen display. Although nothing is initially recorded in the internal database of the network management system 1, the data is gradually accumulated by the notification from the control unit 23 or gradually recorded in the network connection management information recording unit 22. Whether the network connection configuration management table is recorded in the internal database at once. As a result, when data is stored in the internal database, the internal database is updated by the above-mentioned operation.

As described above, the network connection management information recording unit 2 stores the configuration information of the connected network equipment 3-i.
2 and collects the communication address of the network device 3-i when the communication unit 20-i determines that the network device 3-i is newly connected, and based on the determination result and the collected communication address. By updating the configuration information of the network device 3-i and notifying it to the network management system 1, the connection configuration information of the communication network can be automatically collected. Therefore, the time required for creating and inputting the internal database of the network management system 1 becomes unnecessary, and at the same time, the risk of a failure in the communication network due to an error in the internal database or an input error can be reduced.

Further, since it is possible to immediately notify the higher-level network management system 1 of the additional change of the network device 3-i, it is possible to follow the change of the network configuration in real time.

[0021]

As described above, according to the present invention, the contents of the storage means for storing the configuration information of the connected network equipment are collected when it is determined that the connection status of the network equipment is monitored and the connection status is determined. By making changes based on the identification information of the network devices that have been registered and notifying the network management system of the changes, the work of inputting the mutual connection relationship between the network devices and communication lines as a database is unnecessary, and input errors, etc. There is an effect that it is possible to reduce the risk of occurrence of a failure in the communication network due to.
