Abstract
VC multicast implementation scheme utilizing VP tunneling over public ATM VP switched networks utilizing P P and P M 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 P P VP tunnels. A P P VP tunnel is established from each VC switch to all other VC switches connected to the public ATM network. A dedicated P M 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 P M VP tunnel used to transmit data associated with all P M calls for all the P P VP tunnels carried by the physical interface.
