ABSTRACT:
Disclosed is a network system capable of transferring data at a high speed between multicast-supported networks via a L2 network. The network system includes a multicast-unsupported L2 network, two multicast-supported network, two gateway devices for connecting one of the multicast-supported networks to the multicast-unsupported L2 network, and each of witch is capble of assembling, when a multicast data packet is transmitted from the side of the multicast-supported network, a L2-network packet in which a destination MAC address of the multicast data packet is translated into a MAC address of the other gateway device, and transmitting the L2-network packet over the L2 network.
