Control Node, Control Method, And Control Program

Abstract: In an optical communication system which includes a node (104) and a plurality of nodes and in which optical communication is continued through a node where power interruption has occurred, the node (104) comprises: a transmission and reception unit (104f) which receives an optical signal through one or more ports of a port (104a) and a port (104b); and a control unit (104g) which, on the basis of the optical signal received through the port (104a), detects occurrence of power interruption, and calculates a first path cost by weighting a path cost corresponding to the port (104a) with a weight. The control unit (104g) restricts the optical communication through the port (104a) when the first path cost has the largest value among the first path cost, a second path cost which is a path cost corresponding to the port (104b), and a path cost corresponding to each port of one or more nodes receiving power supply among the plurality of nodes.
