COMMUNICATION SYSTEM, CONTROL APPARATUS, AND CONTROL METHOD THEREOF

摘要

Provided is a communication system capable of reducing the load on a controller by causing the controller to collectively calculate paths for packets that relate to each other. The communication system comprises: a plurality of nodes; a first node transmitting a request for a processing rule for processing a first packet; and a control apparatus comprising a first means (unit) determining a first processing rule corresponding to the first packet in response to the request and preliminarily determining a second processing rule corresponding to a second packet that relates to the first packet and a second means (unit) notifying the first node of the first processing rule and notifying at least one of the plurality of nodes of the second processing rule.
