Abstract
A communication system includes a control device, a forwarding node, and a confirmation unit. The control device sets a forwarding path of a packet and determines processing rules corresponding to the forwarding path. The forwarding node includes a processing unit that processes a received packet by a processing rule transmitted from the control device, and a matching information processing unit that adds matching information, which represents information on processing for the received packet, to the received packet and forwards the received packet. The confirmation unit confirms if the forwarding node and the control device are synchronized according to whether the matching information added to the received packet matches pre-calculated matching information.
