摘要

A special management node is installed for efficient network configuration management. When a first node starts communication with a second node, the node sends a request for information on the position of the node of the communication party to a management node. Upon receiving the node position information request, the management node references a network configuration information table and calculates information on a path from the node to the node of the communication party. The management node notifies the calculated path information. Using this path information, the node can communicate with the node of the communication party. Each node notifies, as necessary, the management node of node-to-node connection information that is link information on the neighboring nodes. When a newly connected node sends a request for an optimum node to be connected, to the management node; the management node selects an optimum node to be connected based on the network configuration information it holds and notifies the newly connected node of the selection result. The newly connected node connects to the optimum node according to the contents of the sent information.
