Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a command log synchronization system for a network management device, and more particularly to a command log synchronization system for a network management device that reduces the processing load on the command log synchronization by the network management device.

[0002]

2. Description of the Related Art In the conventional command log synchronization method of a network management device, a response signal to a command sent by the network management device is sent back only to the source network management device, and therefore each network management device has its own configuration. I could not have only the command log (record) information for the command issued by. Therefore, when it is necessary to synchronize the command log information of the network management device, it is necessary to distribute (transmit) the command log information to other network management devices when the network management device receives the command response signal. was there.

FIG. 3 shows a system configuration diagram showing an example of a conventional command log synchronization system. In FIG. 3, stations A,
B and C have O & M nodes 1, 2 and 3, respectively, and perform maintenance and operation management in each station. Network management device 4, 5
Is a network management device for inputting / outputting a command to / from each station and outputting a failure message, and has storage units 41 and 51 for storing command log information, and output means such as a display and a printer. Further, the network management device 4 has an in-network address “400”, and the network management device 5 has an in-network address “500”.
have. The O & M node 1 receives the command signal from the network management device, holds the address of the command management unit 10 that executes the command execution process and creates the response signal, and the address of the network management device that issued the command. It has a call control unit 11 for setting a path to and. Similarly, the O & M nodes 2 and 3 have command execution units 20 and 30, respectively.
30 and call control units 21 and 31.

Next, the operation of the conventional example will be described. When a command signal is input from the network management device 4 to the station A, O
The command execution unit 10 of the & M node 1 executes the command execution process and creates a command response signal, and uses the call control unit 11 to establish a path A with the network management device 4 (address “400”) of the command transmission source. After setting, a command response signal is sent to the network management device 4. The network management device 4 stores the received command response signal in the storage unit 41 as command log information. Further, if it is necessary to synchronize the command logs between the network management devices, the network management device 4 sets a path D with the network management device 5 and transmits the command log information to the network management device 5. The network management device 5 receives the command log information and stores it in the storage unit 51.

Similarly, when the command signal to the station C is input from the network management device 5, the command execution section 30 of the O & M node 3 executes the command execution process, creates a command response signal, and causes the call control section 31 to operate. A path C with the network management device 5 (address “500”) that is the command source is set by using the command response signal to the network management device 5. The network management device 5 stores the received command response signal in the storage unit 51 as command log information. Further, the network management device 5 sets a path D with the network management device 4 and transmits command log information to the network management device 4. The network management device 4 receives the command log information and stores it in the storage unit 4
Accumulate to 1.

By these processes, the command log information of the storage unit 41 of the network management apparatus 4 and the storage unit 5 of the network management apparatus 5 are stored.
It was kept in sync with the command log information of 1.

[0007]

However, in the above-mentioned command log synchronization system of the network management apparatus, the response signal to the command signal sent by the network management apparatus is only sent to the source network management apparatus. Since it is not returned, each network management device cannot hold only the command log information for the command issued by itself. Therefore, when it is necessary to synchronize command log information between network management devices, it is necessary to distribute the command log information to other network management devices when the network management device receives the command response signal. It was For this reason, when the number of network management devices increases, there is a problem that the processing load for synchronization after completion of execution becomes heavier than the command processing of the network management devices themselves.

The present invention has been made in view of the above problems, and it is not necessary to send and receive command log information between network management devices in order to synchronize command log information between network management devices. It is an object of the present invention to provide a command log synchronization method for a network management device that can reduce the processing load on the synchronization of the network management device.

[0009]

In order to achieve the above object, the command log synchronization method of the network management apparatus of the present invention is a station having a maintenance operation node that controls maintenance and operation functions in the station,
A communication network that has a plurality of network management devices that each have an I / O interface for maintenance and operation commands to each station and that has a command log function, and that each network management device can input commands to the maintenance and operation node of each station. In the above, a command control device that receives a command response signal from the maintenance and operation node to the network management device and sends a command response signal to the registered network management device is provided, and the command is input from the network management device to each station and the command is executed. After the processing is completed, the command control device receives the command response signal from each station, transmits the command response signal to the plurality of registered network management devices, and each network management device is based on the command response signal. It is configured to accumulate command log information.
