Abstract:
A topology information automatic configuration method for configuring topology information indicating how to connect each equipment, based on configuration information, including equipment name, IP address, and subnet mask, established for every interface of management equipment and a plurality of managed equipment connected to a network, comprising the steps of:a network address calculation step for obtaining network address of a subnetwork to which an interface is connected, as for every interface, based on the IP address and the subnet mask of the interface, and storing a pair of the obtained network address of each interface and the equipment name of the corresponding equipment having the interface, into an address list storing unit; a management equipment key address registration step for storing a pair of the network address of an interface owned by the management equipment which is obtained in said network address calculation step and the corresponding equipment name, into a key address list storing unit; a pickup step for picking up the same information as that of the head of the network addresses stored in the key address list storing unit, from the information of each interface stored in the address list storing unit, and storing the same into a pickup information storing unit; and a topology information configuration step for configuring the topology information indicating that the equipment having an interface whose information is stored in the pickup information storing unit in said pickup step, is connected to the identical subnetwork represented by the network address within the information and that the equipment having a plurality of interfaces, of all the equipment each having an interface whose information is stored in the pickup information storing unit, connect together the subnetworks indicated by the network addresses of the plurality of interfaces stored in the address list storing unit.
