NETWORK MANAGEMENT METHOD, DEVICE THEREFOR AND NETWORK SYSTEM

摘要

PROBLEM TO BE SOLVED: To improve flexibility in constitution or in a processing system of a network by performing management of the network for each local partial network and performing communication between nodes while propagating spatial searches through an assumption base connection. SOLUTION: Respective subnetworks 11-16 are connected through routers (nodes) R21-R28. The management of the network is performed for each subnetwork at mediators M31-M36 provided for each of respective subnetworks 11-16. The connection between nodes is performed by the assumption base connection for assumptively constructing a path between the nodes. Namely, the node at the connection source outputs a connection request to the mediator. The mediator detects any route, for which it is possible to let the connection destination exist, and outputs that connection request through that route. Thus, the connection request is successively propagated.
