Title:
COMMUNICATION SYSTEM, NODE, CONTROL APPARATUS, COMMUNICATION METHOD AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2011/149003
Kind Code:
A1
Abstract:
This invention provides an arrangement for preventing any unintended processing from being executed due to delay of setting a processing rule (flow entry) or the like at a node placed on a data transfer network. A communication system comprises: a node that processes a received packet; and a control apparatus that sets, to the node, a processing rule that specifies a comparison rule and a packet processing suitable for the comparison rule. The node holds the processing rule with an identifier associated with the processing rule, and, according to whether the identifier of the received packet corresponds to the identifier associated with the processing rule corresponding to the comparison rule suitable for the received packet, determines whether to execute the processing of the received packet in accordance with the processing rule corresponding to the comparison rule suitable for the received packet.
