<p>When an appliance, which has a packet discard function, discards a packet, transmits packet discard information as information related to the discarded packet to a controller. A controller performs a switch control process in response to the packet discard information. In the switch control process, the controller selects a target switch from the network, creates entry setting information for instructing the target switch to create an entry such that a packet belonging to the same flow as the discarded packet is discarded, and transmits the created entry setting information to the target switch. The target switch sets an entry in its own flow table in response to the entry setting information transmitted from the controller.</p> |
