COMMUNICATION SYSTEM, CONTROL DEVICE, NODE, NODE CONTROL METHOD, AND PROGRAM

摘要

A control device is connected to a node and to a packet processing unit. The node operates according to a processing rule that includes a matching rule, against which a received packet is matched, and processing content applied to a packet that matches the matching rule. The packet processing unit performs packet processing according to a predetermined specification. The control device inputs a packet, received from the node to request to create a processing rule, to the packet processing unit in response to a request from the node. The control device creates a processing rule corresponding to a packet processing result of the packet processing unit obtained as a result of the input and sets the created processing rule in the node.
