<P>PROBLEM TO BE SOLVED: To suppress increase in power consumption when at least a part of transfer paths of traffics is changed. <P>SOLUTION: A state data acquisition unit 1d of a router 1 identifies paths of traffics to be transferred involving a specified link as target paths, and finds paths which share their beginning and ending routers with any one of the target paths and do not involve the specified link as candidate for distributed paths. Then, the state data acquisition unit 1d obtains state data of each candidate distributed path from a management apparatus managing state data indicating states of routers that forward traffics on the candidate distributed paths. On the basis of the state data of each candidate distributed path, a distribution destination determination unit 1e preferentially determines a path that minimizes the increase in power consumption due to a change in the states as a distribution destination path. A distribution requesting unit 1f transmits a distribution request to the beginning router of a target path so as to distribute at least a part of the traffic on the target path to the distribution destination path. <P>COPYRIGHT: (C)2011,JPO&INPIT |
