Abstract
A communication system includes a control device configured to calculate a packet forwarding path and set a flow based on the packet forwarding path in a node, and a plurality of nodes configured to forward a received packet based on a flow set by the control device. The control device, when receiving a detour instruction, calculates a new packet forwarding path which detours a detour target node and sets a flow based on the new packet forwarding path in the plurality of nodes on the new packet forwarding path.
