Abstract
A route control system includes a status measuring unit, a cost management unit, a route determining unit, and a route setting unit. The status measuring unit checks a status of each node included in a network. The status is a wake state or a sleep state. The cost management unit updates a link cost for a link connected to a node in the wake state to a value smaller than any link cost for a link connected to a node in the sleep state. The route determining unit determines an optimum route connecting a first terminal to a second terminal. A sum of the link costs for the optimum route is lowest among the link costs for other available routes connecting the first terminal to the second terminal. The route setting unit sets a requested data flow in the optimum route.
