Communication network management system, method and program, and management computer

摘要

A communication network includes a plurality of nodes and a plurality of links connecting between the nodes. A management computer managing the communication network has a storage means, an entry control means and a monitoring means. A route information indicating a transfer route of frames in the communication network is stored in the storage means. The monitoring means performs, based on the route information, transmission and reception of frames to and from the communication network. The entry control means instructs each node to set up a forwarding table indicating a correspondence relationship between an input source and a forwarding destination of frames. More specifically, the entry control means instructs the each node to set up the forwarding table such that frames are forwarded along the transfer route indicated by the route information.
