Abstract:
1. An information processing method for managing paths between arbitrary nodes in a network, said information processing method making a computer execute a process comprising: identifying, for each of a plurality of path candidates between specific nodes, a static transmission bandwidth that is minimum among bandwidths of links belonging to a corresponding path candidate; restricting the plurality of path candidates to particular path candidates based on the static bandwidth identified for each of the plurality of path candidates; obtaining, for each of said particular path candidates between specific nodes, first data concerning a utilization state of each link included in the path candidate, from nodes in said network; calculating, for each said link included in said particular path candidates, a first bandwidth that is an available bandwidth in the link by using said first data and second data of the bandwidth for each said link included in said particular path candidates; identifying, for each of said particular path candidates, a minimum bandwidth among said first bandwidths of said links included in a corresponding particular path candidate, as a dynamic transmission bandwidth of the corresponding particular path candidate; and storing the identified dynamic transmission bandwidth into a management data storage device.
