ABSTRACT:
The present invention relates to a system and apparatus for tunneling service of explicit multicast, to efficiently transmit an explicit multicast of a packet to plural destinations. A tunnel ingress node is receives an explicit multicast packet from a sender terminal, which the explicit multicast packet has to be transmitted to plural addressee terminals. And, after the tunnel ingress node recognizes tunnel egress nodes using plural addresses terminal's address in the explicit multicast packet, it creates a tunnel header comprising transmission destinations based on the list of the recognized tunnel egress nodes. And then, the tunnel ingress node creates a tunnel packet encapsulated with the explicit multicast packet and the tunnel header, transmits the tunnel packet to the tunnel egress nodes. The tunnel egress nodes extract the tunnel header from the tunnel packet, and transmit the explicit multicasting packet to plural addressee terminals using the destination address of the tunnel header.
