Information processing device, information processing method, and non-transitory computer readable memory

A network management apparatus is designed so that when reassigning the existing address, the network management apparatus extracts a link with the largest link cost from among links comprising the network based on the network configuration information and specifies a flow routed though the extracted link based on the statistic information; when receiving a path change request and a via link request to request a via link with respect to the specified flow from an external terminal, the network management apparatus selects either one of addresses of an address pair of the specified flow as a change target address; and when changing the selected change target address, the network management apparatus changes the change target address to a candidate address to be assigned by selecting an address, which is routed through a link included in the via link request and has not been assigned, as the candidate address to be assigned.
