  • Multicast network unit, multicast network system, and multicast method
    Patent number: 7570635
    Abstract: 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.
