摘要
VC multicast implementation scheme utilizing VP tunneling over public ATM VP switched networks utilizing P2P and P2M connections to provide VC multicast capability to the attached private ATM networks. The border ATM VC switch in each private ATM network is connected to the ATM VP switch in the public ATM network via a physical interface adapted to carry one or more P2P VP tunnels. A P2P VP tunnel is established from each VC switch to all other VC switches connected to the public ATM network. A dedicated P2M VP tunnel is established between the source VC switch to each of the destination VC switches connected to the public ATM network. For each multicast connection to be established, a VPI/VCI value pair is allocated over the dedicated P2M VP tunnel used to transmit data associated with all P2M calls for all the P2P VP tunnels carried by the physical interface.
