摘要
A communication system includes a plurality of nodes and a control device. Each node includes a packet processor that processes a packet in accordance with a processing rule when the packet is received. The processing rule correlates the processing applied to the packet with a matching rule that identifies the packet the processing is to be applied to. The control device calculates a packet forwarding path in response to a request for setting processing rules from any node, sets processing rules that implement the packet forwarding path on the node on the packet forwarding path and records the processing rules in a manner coordinated with one another. The control device inquires at the node on the packet forwarding path about state of setting of processing rule and, upon detecting failure in the processing rule set in at least one node, executes rollback operation on the correlated processing rules set in other node.
