A source node, along with transmitting an optical path setup request, notifies towards a destination node available resource information related to itself, pre-assigns the available resources which its own node has notified. Each of transit nodes, along with relaying towards the destination node the optical path setup request which has been received from a previous hop node, notifies towards the destination node available resource information related to itself, and pre-assigns the available resources which each of their own nodes has notified. The destination node, along with reserving a resource which is to be used for setting up an optical path based upon an optical path setup request which has been received, transmits a resource reservation request towards the source node. The transit nodes and the source node actually reserve an available resource which has been pre-assigned, based upon a resource reservation request from a next hop node.
