  • Ingress gateway selection for a shortest path bridging network to support inter domain multicast routing
    Patent number: 10680931
    Abstract: In a Shortest Path Bridge (SPB) network comprising a plurality of backbone edge bridges (BEBs), a gateway controller of the SPB network, establishes a link using Multicast Source Discovery Protocol (MSDP) with an external network domain; discovers via the link a source of a multicast stream originating outside of the SPB network; and determines a subset of the plurality of BEBs that are able to receive the multicast stream from the source. Once that occurs, the gateway controller selects a one of the subset of the plurality of BEBs to be a sole gateway BEB for the multicast stream; and then transmits to each of the subset of the plurality of BEBs an indication of the sole gateway BEB selected for the multicast stream.

  • Protocol independent multicast (PIM) snooping for a shortest path bridging multicast (SPBM) network
    Patent number: 9755845
    Abstract: A method and apparatus for providing Protocol-Independent Multicast (PIM) snooping for a Shortest Path Bridging Multicast (SPBM) Network is presented. An ingress Backbone Edge Bridge (BEB) device of a Shortest Path Bridging (SPB) network having at least one egress BEB coupled to at least one PIM network performs the following operations. The egress BEB, snoops join and prune messages for a multicast stream in the SPB network. A multicast tree is built in the SPB network for the multicast stream in accordance with the join and prune messages. The multicast stream is forwarded through the SPB network in accordance with the multicast tree.
