A total electric power amount calculating means (81) calculates a total electric power amount that can be used by each of a plurality of communication apparatuses within a predetermined time period. An available electric power calculating means (82) calculates an electric power amount, which is available to each communication apparatus in a designated time frame, on the basis of both the total electric power amount and a distribution function that is a function defining the ratio of available electric power in a given time frame within the time period. When a time frame in which a traffic is to be accommodated is designated and a path setting request is made, an available electric power amount determining means (83) determines, for each communication apparatus on the communication path, whether a consumed electric power, which is an electric power amount required to accommodate the traffic in the time frame, exceeds the available electric power amount. |
