Abstract:
1. A route control system to determine a route for a data flow in a network including a plurality of nodes and a plurality of links, each of the plurality of links connecting two nodes out of the plurality of nodes or connecting one of the plurality of nodes to one of a plurality of terminals, the route being a chain of links out of the plurality of links and connecting two terminals out of the plurality of terminals, the route control system comprising: a memory; and a processor executing: wherein the updating stores in the memory, as the link cost for the link connected with the node in the sleep state, an amount corresponding to power consumption of the node in the sleep state and the updating updates the link cost for the link connected with a retired node to an amount corresponding to a power consumption of a retired node when the checking has detected that an active node has been shifted to the retired node after all data flows passing through the active node have completed, and wherein the active node is in the wake state, and the retired node is in the sleep state.
