  • Source specific multicast layer 2 networking device and method
    Patent number: 8503445
    Abstract: Bridge domain communication methods and devices are presented for efficiently communicating information in a bridge domain based upon group indications and source indications. Packets with a source and destination indication are received. A bridge domain communication process is performed at the bridge level wherein a packet is selected for forwarding based upon a source and group indication. For example, a determination is made if a particular bridge domain corresponds to the group destination indication in the received packet. The source indication in the packet is compared with a tracked source designation indication. Output ports associated with the tracked source designation indication are identified if the tracked source designation indication matches the received source indication. The communication packet is forwarded on identified ports.
