  • 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.

  • Publication number: 20080072308
    Abstract: A security management apparatus temporarily holds a session establishment request by a terminal apparatus 3 then determines permission or refusal of the session establishment request based on terminal management information. If permission is determined, the apparatus determines whether or not the security state of the source terminal apparatus is the latest one based on security management information. If it is determined not to be the latest one, then the apparatus sends out a session establishment request in which the terminal apparatus and a security information management apparatus are set as the source and the destination. After that, when update of the security of the terminal apparatus is notified, the held session establishment request by the terminal apparatus is sent out. On the other hand, if the security state is determined to be the latest one, the held session establishment request by the terminal apparatus is sent out.
