Patent ID: 8705959

Claim:
An optical network designing device that designs a path of an optical network that includes an asymmetric optical hub site, comprising: a memory; and a processor coupled to the memory and configured to execute a process, the process including: calculating a requested traffic path without a limit to a number of connections of the asymmetric optical hub site; determining whether a limit to the number of connections is violated in the asymmetric optical hub site through which the traffic path calculated by the calculating passes; selecting a removal connection to be removed from the determined asymmetric optical hub site when it is determined by the determining that the limit to the number of connections is violated; and calculating a traffic path that passes through the asymmetric optical hub site from which the removal connection selected by the selecting has been removed; wherein the selecting selects, as the removal connection on a priority basis, a connection between ports that each have more than the limit to the number of connections and are included in the asymmetric optical hub site.
