Abstract:
A method, apparatus and computer program product for providing multi-homing techniques for SPB networks is presented. A set of UNI nodes that receive multicast packets are determined based on Backbone Media Access Control-Destination Address (BMAC-DA)/I-Tag Service Identifier (I-SID) of received multicast packets for multicast packets within a transport network. A separate Egress Port Mask is determined for each Backbone-Virtual Local Area Network (B-VLAN) of the transport network, wherein the Egress Port Mask is determined such that only one UNI node of the set of UNI nodes forwards said multicast packets. A set of UNI copies of said multicast packets are filtered out by applying the Egress Port Mask, wherein copies that are not in the Egress Port Mask are dropped. Copies of multicast packets that are not dropped are sent out.
