Abstract： |
The method comprises: establishing a virtual allocation network for each multicast session in network; the virtual allocation network is composed of the user's host machine participating the multicast session and the selected nodes; said host machine and nodes are connected through virtual link and have unique ID; in the virtual allocation network, when sending service data, the sending host machine sets IP address of receiving host machine as IP address ID of virtual allocation network; each node on the virtual allocation network allocates IP packets until the IP packets are transmitted to all receiving host machine in the virtual allocation network. |
