COMMUNICATION SYSTEM, NODE, PACKET FORWARDING METHOD AND PROGRAM
First Claim
1. A communication system, comprising a node holding a plurality of packet handling operations which correlate the forwarding destination of a packet belonging to each flow with a set of collation rules that identify each flow;
- the node forwarding the packet received in accordance with the packet handling operations;
wherein,in case the destination address of the received packet is such address indicating that the received packet is to be multicast, the node multicasts the packet using the plurality of the packet handling operations the node holds.

Abstract
Even though the number of communication terminals or that of communication services exploited by the communication terminals is increased, load imposed on a node or a controller is to be less likely to be increased, while delay in processing is to be less likely to be produced. Each node of a communication system holds a plurality of packet handling operations which correlate the forwarding destination of a packet belonging to each flow with a set of collation rules that identify each flow, and forwards the received packet in accordance with the processing rules. In case the destination address of the received packet is such address indicating that the packet is to be multicast, the node multicasts the packet using the plurality of the processing rules the node holds.
