MULTICAST PACKETS FORWARDING METHOD, APPARATUS AND MULTICAST SYSTEM

摘要

A method for forwarding multicast packets is used to forward multicast packets from an ingress node to egress nodes of a multicast group in a network domain, and at least one network node in the said multicast network domain performs the following steps: having received a multicast packet of a multicast group; determining the node information of the egress nodes that the multicast packet needs to reach, wherein the said egress nodes that need to be reached include the egress nodes which join in the said multicast group successfully; adding the node information of the egress nodes needing to be reached by the multicast packet to the said multicast packet; sending the multicast packet which carries the node information of the said egress nodes. There are also an apparatus for forwarding multicast packets and a multicast system.
