<p><P>PROBLEM TO BE SOLVED: To provide a routing setting system that prevents concentration of loads while using the link cost for a parameter for routing setting in a communication system. <P>SOLUTION: When path routing setting is conducted, a routing processing section in a communication node executes the path routing setting, so as to minimize the evaluation function by using the evaluation function whose parameter is a monotonously increasing value (dynamic link cost), with respect to the number of paths passing through a link or is expected to pass through the link as the initial value of the link cost. Since the routing cost can be set, depending on the number of the paths or on the required band, concentration of traffic on a particular routing is prevented, and the utilization efficiency of the network as a whole can be enhanced. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
