Abstract

There is installed a special management node to efficiently perform network configuration management. When a node starts communication with another node, the node sends a request for node position information about the communication counterpart node to a management node. Upon receiving the node position information request, the management node references a network configuration information table to calculate information about a route from the node to the communication counterpart node. The management node notifies the calculated route information. By utilizing the route information, the node can communicate with the communication counterpart node. Each node notifies node-to-node connection information, information about links with adjacent nodes, to the management node as necessary. When a newly connecting node requests an optimum connection target from the management node, the management node selects an optimum node to connect to, based on network configuration information it holds and notifies it to the newly connecting node. The newly connecting node connects to the optimum node in accordance with the contents of the notified information.

Description

Technical field [0001] The present invention relates to a management node device, a network configuration management system and a network configuration management system, and in particular to a management node device for managing node devices constituting a network, and a network configuration management system and network configuration management method using the management node device. Background technique [0002] Figure 28 Display a network composed of multiple node devices. Now, an example of communication conditions of information about node devices constituting a network, that is, network configuration information, will be described with reference to the drawings. In the following description, the node device may be simply referred to as "node". [0003] In the figure, the network has six nodes 101 to 106. When the network configuration information at the node 101 is changed, the changed network configuration information is transmitted to the adjacent nodes 102 and 103. ...

AI Technical Summary

Problems solved by technology

When routing information requests are transmitted sequentially as described above, there is a problem that it takes time until information about the route to the destination node is obtained

So, there is a problem: it takes time before the changed network configuration information is transmitted to all nodes

[0010] Moreover, as shown in Figure 29A and Figure 29B The shown method of connecting to any one or more nodes has a problem: if Figure 30A As shown, generate redundant routes, and build a network with high redundancy

Moreover, there is another question about the configuration of the entire network: if Figure 30B As shown, constructing an uneconomical linear topology
