Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is used for network management means for monitoring and controlling a communication network. In particular, the present invention relates to a communication control device that controls communication between a center device as a management system and a network element of the managed system.

〔Overview〕

The present invention relates to a communication control device for monitoring and controlling a plurality of lower monitored devices by a plurality of center devices, wherein a means for connecting a desired center device to the desired lower monitored device is provided. This makes it possible to equalize the burden on the control.

[Conventional technology]

In the conventional example, a single center device is connected to a plurality of network elements, and control and monitoring information of the managed network transmits control information from the single center device to the plurality of network elements in accordance with the order of occurrence of the event. In addition, the monitoring information collected from a plurality of network elements is transmitted to a single center device.

[Problems to be solved by the invention]

In such a conventional example, since the control and monitoring of the managed network are performed by a single center device, the managed device is limited by the processing capacity of the center device when the size of the managed network increases. There is a drawback in that the communication control device and the sensor device must be arranged separately by dividing the network.

Further, in the conventional example, since the control and monitoring information follows the order of occurrence of events, even when it becomes necessary to perform urgent control on the managed network, the control and monitoring information is already stored in the transmission / reception wait register of each device constituting the management network. Further, when there are a plurality of pieces of monitoring information, there is a disadvantage that information requiring a new urgency cannot be transmitted and received until they are transmitted and received.

An object of the present invention is to provide a communication control apparatus which eliminates such a drawback and can easily cope with an increase in the scale of a managed network.
