A communication system reduces load on a control device managing centralized control of a plurality of nodes. The communication system includes nodes and a control device. On receipt of a packet, each node references a table including a plurality of processing rules concerning packet processing to process the received packet in accordance with at least one processing rule corresponding to the received packet. If the corresponding processing rule is not known, each node transmits a processing rule setting request.

A request staying unit that transiently stays the setting request to the control device is provided in such one or more nodes.
