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 communication control and so on. When the configuration of the network is changed due to movements of nodes and so on, an administrator inputs the contents of update from the manager of each layer, so that the manager communicates with a node containing corresponding management information to instruct the node to update the management information. |

DETAILED DESCRIPTION It is therefore an object of the present invention to provide a network managing method and system which allow an administrator to easily register and update management information even when the configuration of a network is modified over a plurality of related virtual closed area networks. The present invention provides a network managing method and system for use in a network having a plurality of communication terminals and at least one switch circuit for controlling communications between the communication terminals for registering and updating management information which defines the operations of the communication terminals and the switch circuit. The method defines a plurality of virtual closed area networks each having the communication terminal or the switch circuit selected in accordance with a predetermined rule, and defines the management information for each of a plurality of logical hierarchies segmented in accordance with a predetermined rule. The communication terminals and the switch circuit each belong to one of the closed area networks or the logical hierarchies, and have storage means for storing management information on the closed area network or the switch circuit to which it belongs. At least one of the communication terminals communicates management information to be registered and updated among the communication terminals and the switch circuit, which store the management information to be registered and updated, based on inputted information, and manages the registration and update of the management information for each of the closed area networks and for each of the logical hierarchies. The network managing system according to the present invention defines a network having a switch circuit based on a logical configuration, and defines management information on the network for each virtual closed area network and for each logical hierarchy for management. In addition, the management information can be registered and updated also on each logical hierarchy
