A configuration having a control device that sets a processing rule in a forwarding node, the configuration being capable of forwarding control of duplicated packets in private IP address spaces. At least one forwarding node among forwarding nodes operates as a logical channel control device that establishes a logical channel to an external node, makes an association with the logical channel established for a communication terminal to generate or delete virtual port information, and gives notification thereof to the control device, and the control device computes a forwarding path of a packet using the notified port information. |
