Abstract
A route designing method in which there is accepted an input of user information containing information about bandwidth of an access link serving as a link for connecting each of user sites to a relay node, and information showing the relay node connecting to the user site via the access link, topology information of a network for relaying the communications between the user sites is acquired, a communication relay port and a communication non-relay port are obtained based on the user information and the topology information, an upper limit of the communication bandwidth available for the user on the communication relay port is obtained, a route design so that the user sites are connected by a tree-shaped route is performed, and a result of the route design is outputted.
