Communication system, communication device, controller, and method and program for controlling forwarding path of packet flow

摘要

A communication system includes a communication device controlling packet forwarding, and a controller setting a first table entry used for packet forwarding according to a request from the communication device. The communication device determines whether to forward a received packet according to the first table entry or forward the received packet according to a second table entry set by the communication device based on a rule for identifying a received packet. The load of the controller for controlling paths can be reduced.
