The present invention provides a configuration that prevents unintended processing, which may be generated due to a delay in setting a processing rule (flow entry), from being executed in a node arranged in a data forwarding network. A communication system includes a node that processes a received packet; and a control device that sets a processing rule, which defines a matching rule and processing for a packet that conforms to the matching rule, in the node. The node holds an identifier in association with a processing rule and determines whether or not to perform processing for a received packet depending upon whether or not an identifier of the received packet corresponds to an identifier associated with a processing rule corresponding to a matching rule that conforms to the received packet, wherein the processing is performed according to the processing rule corresponding to the matching rule that conforms to the received packet. |
