Abstract
A switch transfers a predetermined packet to an appliance. The appliance generates a rewritten packet by carrying out the packet header rewriting on the predetermined packet and forwards the rewritten packet back to the switch. The switch transfers the rewritten packet received from the appliance to a controller. In a case when the rewritten packet meets a predetermined condition, the controller generates entry setting data which instructs to set a new entry on the basis of a destination of the rewritten packet and the predetermined rewriting mode, and sends the entry setting data to the switch. The new entry indicates that packets belonging to the same flow as the predetermined packet are transferred to the destination without being routed through the appliance. The switch adds the new entry to the flow table in accordance with the entry setting data received from the controller.
