Abstract

See full text

The present invention relates to a solution for taking a network equipment in a communication network as a root node to generate a logical topology tree for a subscriber terminal which requests the sending of multicast packets, and then generating a multicast tree on the logical topology tree with the network device as the root node, so as to forward the multicast packets. With the solution of sending a multicast packet to the subscriber terminal, it can effectively save the network bandwidth resource and reduce the transmission delay of multicast packet.
