A network managing method which divides a network to be managed into a plurality of virtual closed area networks, and defines management information on the virtual closed area networks separately in a plurality of logical hierarchies. A virtual LAN/network space defines a connection state among closed area networks, a closed area space defines attribute information on nodes within a closed area network, and a virtual service defines logical arrangement information on nodes in the overall network. The management information is distributively stored in each node and utilized for MAC control. When the configuration of the network is changed due to movements of nodes, an administrator inputs the contents of the change from the manager of each layer, so that the manager communicates with a node containing corresponding management information to instruct the node to update management information.
