<p>The objective of the invention is to allow a communication node, which operates in accordance with control information established from a control apparatus, to perform different processes by use of a reduced number of flow tables. A communication node comprises: one or more flow tables that store several pieces of control information established from a control apparatus; and a packet processing unit that retrieves, from the one or more flow tables, a piece of control information having a match condition conforming to a received packet and that processes the packet in accordance with the retrieved piece of control information. If a given loop order has been added to the piece of control information having the match condition conforming to the received packet, the packet processing unit executes both the retrieval of another piece of control information in the flow tables and the execution of the retrieved piece of control information a predetermined number of times.</p> |
