Abstract
A control apparatus comprises: a switch extraction unit extracting a second switch adjacent to a first switch that stops in a communication system including a plurality of switches having a predetermined topology; a flow extraction unit extracting a flow transferred to the first switch after the second switch from a plurality of flows passing through the communication system; a path determination unit determining, assuming that, among the plurality of switches, switches located at start and end nodes of the flow are third and fourth switches, respectively, a path from the second switch to the fourth switch, based on a topology obtained by excluding the first switch from the predetermined topology; and a path generation unit connecting a path from the third switch to the second switch in an initial path of the flow and a path determined by the path determination unit to generate a new path of the flow.
