Abstract:
1. A network management system for managing a plurality of packet relay devices, the network management system comprising: the plurality of packet relay devices constituting networks; and a display device for displaying configurations of the networks, wherein each of the plurality of packet relay devices can generate at least one virtual packet relay device, wherein the virtual packet relay devices generated in the plurality of packet relay devices constitute a plurality of virtual first networks, wherein each of the virtual packet relay devices is assigned a virtual packet relay device identifier unique throughout the packet relay device in which the each of the virtual packet relay devices is generated, wherein each of the plurality of virtual first networks can be divided into at least one virtual second network, wherein the each of the plurality of packet relay devices manages, as configuration information, the virtual packet relay device identifier assigned to the each of the plurality of packet relay devices and a second-network identifier which is an identifier of the at least one virtual second network, wherein the network management system further comprises: wherein the first-network identifying module is configured to: wherein, in a case of receiving the display request, the network configuration display module refers to the first-network configuration table and identifies the virtual packet relay device identifier that is associated with the first-network identifier of the given one of the plurality of virtual first networks, to thereby identify the configuration of the given one of the plurality of virtual first networks and display the identified configuration of the given one of the plurality of virtual first networks on the display device.
