Abstract
A mechanism for performing multicast packet transfer when a certain one of the destination nodes participating in the multicast communication requires resource reservation for a certain packet flow specified among the packet flows to that destination node. A system may transfer multicast packets using a plurality of virtual connections based on which flow the packets to be transferred belong to, so that each node receives the packets without duplication. Alternatively, a system may selectively discard received packets to avoid processing duplicated packets, although duplicated packets are received at each node.
