COMMUNICATION SYSTEM, NODE, PACKET TRANSFER METHOD AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2012/081721
Kind Code:
A1
Abstract:
This invention alleviates occurrences such as load increases on nodes and control devices and processing delays, even if the number of communication terminals or the number of communication services used by these communication terminals increases. Nodes of the communication system maintain a plurality of processing rules that associate the transfer destinations of the packets belonging to each flow with collation rules for specifying the flows, and transfer received packets according to the processing rules, and, if the destination addresses of received packets are addresses that indicate they are subject to multicast, perform multicast transfer using the plurality of processing rules maintained.
