Do not send request data on. If it is determined that the transition is possible, a request for updating the state of the network resource is transmitted to the server computer using the operation control connection 1 (41).

Referring to FIG. 5, the server network operation management program (01) refers to the control table in the server program to specify the client computer having the highest share level with respect to the network resource whose status is requested to be updated. Client network operation management program 2 in the client computer
A network resource status update instruction is transmitted to (31).

The client network operation management program 2 (31) having the highest share level has the right to determine whether or not to update the state of the network resource. When the status update is rejected, a response is sent to the server computer to reject the update of the status of the network resource.

The server network operation management program (01), which has received a response from the client network operation management program 2 (31) that refuses to update the state of the network resource, sends the requesting client network operation management program 1 (21). ) Is sent to that effect. In this case, the state of the requested network resource is not updated.

Referring to FIG. 6, when the client network operation management program 2 (31) having the highest share level recognizes that the state of the network resource is to be updated, the client network operation management program 2 (31) notifies the server computer of the network resource. Send a response to allow the status to be updated.

The server network operation management program (01), which has received a response from the client network operation management program 2 (31) indicating that the state of the network resource is to be updated, is transmitted to the communication processing device (1).
The status of the network resource is updated for the communication control program (03) in (0). Then, the execution result of the update processing is transmitted as a response to the requesting client network operation management program 1 (21).

When the server network operation management program (01) updates the state of the network resource in this way, the state transition of the network resource is performed for all client network operation management programs other than the request source that requested the update processing. Send notifications.

Referring to FIG. 7, when the client computer requesting to update the state of the network resource has the highest share level, the server network operation management program (01) performs the communication control as it is. The state of the network resource is updated for the program (03).

[0043]

Next, an embodiment of the present invention will be described in detail with reference to FIGS.

FIG. 8 shows an example in which an update request for a network resource from an operator is rejected by the client operation management program.

As a precondition, a network resource (P
It is assumed that the state of U1) is in the deactivation process. The resource status update request (PU1 activation) input by the operator is rejected because the status of PU1 managed by the operation management program (NWCM) is being deactivated, and a negative response is returned to the operator. You.

FIG. 9 shows an example in which the update request for the network resource from the operator is rejected by the operation management program of another client computer.

As a precondition, it is assumed that the operation management computer 2 has a higher network resource (PU1) share level than the operation management computer 1. The resource status update request (PU1 activation) input by the operator is requested to the operation management (NWCM-F) in the communication control device (FNP), and is sent to the operation management computer 2 having the highest share level by the NWCM-F. Operation management (NWCM)
, An instruction to update the state of PU1 is transmitted. Thereafter, a response indicating that the status update of PU1 is rejected is returned from the NWCM, and a failure response is returned to the operator.

FIG. 10 shows a case where a request for updating the state of the network resource from the operation management in the client computer having a low share level is permitted by the operation management in the client computer having a high share level, and is successfully executed by the server computer. An example is shown.

The resource status update request (PU1 activation) input by the operator is requested to the server operation management (NWCM-F) in the communication control device (FNP), and the operation having the highest share level by the NWCM-F. An instruction to update the state of the PU 1 is transmitted to the operation management (NWCM) in the management computer 2. After that, permission for status update is returned from the NWCM, the activation of PU1 is executed for the communication control program in the communication control device, and P is sent to the operator.
A response of the activation success of U1 is returned. At that time, N
The WCM-F notifies the NWCM of the operation management computer different from the request source of the activation of the PU1. As a result, the state of PU1 becomes active in a plurality of operation managements (NWCMs).

FIG. 11 is an example of processing execution of a resource status update request (PU1 activation) from the operator having the highest share level.

The resource status update request (PU1 activation) input by the operator is transmitted to the server operation management (NWCM-F) in the communication control device (FNP), and the NWCM-F transmits the update request at the share level of PU1. Since the request is from the operation management (NWCM) having the highest rank, PU1 activation is executed for the communication control program as it is, and the success of PU1 activation is returned to the operator. At that time, the NWCM-F notifies the NWCM of the operation management computer different from the request source of the activation of the PU1. As a result, in multiple operation management (NWCM),
The state of PU1 becomes active.

Thus, the processing of the remote operation management system for the network system according to the embodiment of the present invention is completed.

In the remote operation management system for a network system according to one embodiment of the present invention, when the operation management in the communication control apparatus receives an update request for the state of the network resource from the operation management of a certain operation management computer, Only when permitted by the operation management computer with the highest level, the state of the network resource is updated, and the changed state of the network resource is transmitted to the operation management of all the operation management computers. The operation management of all the operation management computers has an effect that the state of the network resource in the communication control device can be centrally managed.

[0054]

As described above, the remote operation management system for a network system according to the present invention provides a network system in which a server computer as a communication control device and a plurality of client computers as operation management computers constitute a server client system. Has the effect that each operation management computer can manage the state of network resources constituting the network system in a unified and distributed manner.
