摘要： 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.

摘要： A multicast network system is provided with a multicast network unit that delivers data between independent multicast network domains. The multicast network unit includes an extraction part for extracting a multicast delivery destination address from received data, a holder part for holding conversion data where the multicast delivery destination address corresponds to a delivery source address, and a judgment part for judging whether the multicast delivery destination address is held and outputting the result of a judgment. The multicast network unit also includes a filtering part which, when the result of the judgment is holding, converts the multicast delivery source address to an arbitrary delivery destination address and, when it is non-holding, discards the received data. The multicast network unit further includes a transmitter part for transmitting data containing the converted multicast address to the domain.
