Abstract
One aspect can provide a system and method for tunnel-based multicasting. During operation, a source-side designated router (DR) coupled to a source device of a multicast group can broadcast a service-advertisement packet and receive a response packet from a client-side DR coupled to one or more client devices within the multicast group. The source-side DR can determine an address of the client-side DR based on the received response packet and establish a hardware-based communication tunnel between the source-side DR and the client-side DR using the address of the client-side DR. Establishing the hardware-based communication tunnel can include using hardware logic units to encapsulate multicast data packets originating from the source device. The source-side DR can further send, over the hardware-based communication tunnel, multicast data packets originating from the source device to the client-side DR, which forwards the multicast data packets to the client devices within the multicast group.
