PROBLEM TO BE SOLVED: To manage a network efficiently while lessening load on the nodes, the network managing units and the network. SOLUTION: A network is divided into a plurality of sub-networks 105-1 to 105-3. Each node 101 belonging to the same sub-network manages the sub- network through distributed control for exchanging information each other. The entire network is managed by centrally controlling sub-network management nodes 104-1 to 104-3, provided at least one for each sub-network and connected with nodes belonging to other sub-network through a transmission path 102, by means of a network management unit 103.
