Abstract
This invention is to provide a technique enabling efficient routing in the entire network by totally viewing a state of the entire network from a specific server. An information processing method for managing paths between arbitrary nodes in a specific network according to the invention, includes: obtaining data concerning a utilization state of each link constituting a path, from associated nodes in the specific network; and calculating a value of dynamic transmission bandwidth in an entire path by using the data concerning the utilization state of each link constituting the path, and storing the calculated value into a management data storage. By the dynamic transmission bandwidth, that is, bandwidth, which can actually be used for communication to be carried out from now, it becomes possible to carry out efficient routing.
