Abstract: Various systems and methods for performing bit indexed explicit replication (BIER) using IPv6. For example, one method involves receiving, at a node, a packet that includes an IP header. The packet also includes a multicast forwarding entry. The method also involves comparing the multicast forwarding entry with forwarding information stored by the node and selecting a neighbor based on the comparing. The method further includes forwarding the packet to the neighbor.

Abstract: Various systems and methods for performing bit indexed explicit replication (BIER) using multiprotocol label switching (MPLS). For example, one method involves receiving a packet that includes a MPLS label. The packet also includes a multicast forwarding entry. The method also involves determining, based on the value of the MPLS label, whether to use the multicast forwarding entry to forward the packet. The method further includes forwarding the packet.

Abstract: In one embodiment, a method includes receiving from a host node comprising a tenant multicast application with a single tenant deployment, an encapsulated multicast packet over unicast at a virtual replicator, the encapsulated multicast packet comprising receiver information for the virtual replicator, replicating the encapsulated multicast packet at the virtual replicator, and transmitting the encapsulated multicast packet over unicast to a plurality of receiving nodes based on the receiver information. The receiving nodes comprise the tenant multicast application and the virtual replicator operates in a cloud without multicast capability. An apparatus is also disclosed herein.

Abstract: Various systems and methods for performing bit indexed explicit replication (BIER). For example, one method involves receiving a packet at a node. The packet includes a multicast forwarding entry. The multicast forwarding entry has a plurality of elements, and each element corresponds to a particular node. The method also involves comparing the multicast forwarding entry with forwarding information stored by the node. The method involves selecting a neighbor node based on the comparing, updating the multicast forwarding entry in the packet, and forwarding the packet to the neighbor node.
