<p>A communication node comprises: one or more flow table(s) that stores a control information item(s) as set by a controller; and a packet processing unit that searches for a control information item, having a match condition matching a received packet, from the one or more flow table(s), and processes the received packet in accordance with the control information item. In a case where a preset loop instruction is added in the control information item having the match condition matching the received packet, the packet processing unit performs a preset number of times of search for another control information item in the one or more flow table(s) and execution of the searched control information item. The communication node, configured for operating in accordance with the control information as set by the controller, is enabled to perform different processing operations despite the use of a smaller number of flow tables.</p> |
