Summary:A network management system (NMS) maintains topology information of a network allowing coexistence of PDH network and SDH network. The network management system (NMS) generates a topology data for path calculation in a path calculation device in accordance with the topology information of the network after converting topology information of the PDH network into topology information of an SDH network. The path calculation device calculates the optimum path in answer to a path calculation request from the network management system (NMS) on the basis of the topology data for path calculation generated therein, and returns the calculation result. The network management system (NMS) reverts the SDH network topology information generated through conversion from the PDH network topology information among the SDH network topology information included in the calculation result received from the path calculation device to the PDH network topology information before the conversion.
