  • Multicast registration of all multicast flows in an asynchronous transfer mode based emulated LAN
    Patent number: 6563830
    Abstract: An apparatus for and a method of implementing multicast registration in an ATM based ELAN. The present invention provides a mechanism for a LEC to register to receive all multicast group traffic flows without requiring the LEC to generate a separate request for each multicast MAC address. The mechanism of the present invention provides means for a LEC to register to receive all multicast flows by defining an ‘all_multicast’ TLV and including this TLV in the LE_REGISTER_REQUEST request message sent by the LEC. The LEC, LES and SMS are modified to perform the multicast registration/unregistration method of the present invention. The LEC generates the LE_REGISTER_REQUEST message and includes the all_multicast TLV indicating that the LEC desires to receive all multicast traffic flows in the ELAN. The LES, upon receipt of such an all_multicast TLV, adds the LEC to its list of LECs to receive all multicast traffic and communicates the related information to the SMS.
