COMMUNICATION SYSTEM, CONTROL DEVICE, METHOD FOR SETTING PROCESSING RULE, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To realize both aggregation of processing rules and facilitation of specifying a flow allowing occurrence of an abnormal traffic.

SOLUTION: A control device performs: writing, to a zone for collating with a collation rule of a packet, a flow identifier for identifying a flow and a path identifier used for a packet transfer in an aggregation-enabled section relating to packet(s) belonging to individual flows transferred, on two or more packet transfer paths, to a node located at a start point of an aggregation-enabled section of the two or more packet transfer paths having the aggregation-enabled section, followed by setting processing rules for respective flows for outputting packets; setting a common processing rule for transferring a packet applicable to the path identifier to a node located in the middle of the aggregation-enabled section along the packet transfer path; and setting a processing rule for performing restoring/transferring to a node located at the end of the aggregation-enabled section on the basis of the flow identifier.
