    Abstract: Various systems and methods for performing bit indexed explicit replication (BIER). For example, one method involves receiving a membership message that was generated by an egress router, where the membership message comprises information identifying a multicast group, and information identifying a plurality of egress routers. The method identifies at least one bit position in the membership message that is associated with the first egress router, where at least one bit position of the plurality of bit positions is associated with the first egress router. The method also records membership of the first egress router in the multicast group, where the membership is recorded in a bit of a group membership table, and the bit corresponds to the bit position identified in the membership message.

    Abstract: Methods, devices and computer readable storage media for performing bit indexed explicit replication (BIER) are disclosed. One embodiment of a method includes obtaining, at an egress node of a network, a bit position assigned to the egress node. This embodiment also includes sending an outgoing advertisement to other nodes in the network, where the outgoing advertisement identifies the egress node and the assigned bit position. The bit position is within a bit mask comprising bits in a plurality of bit positions, and each bit position corresponds to a respective egress node of the network.

    Abstract: Various systems and methods for performing bit indexed explicit replication (BIER). For example, one method involves receiving a membership request at a node. The membership request is received from a host and the membership request identifies a multicast group. In response to receiving the membership request, the node generates a membership message. The membership message includes information identifying the multicast group and information identifying the node. The node transmits the membership to an overlay participant that stores a bit string associated with the multicast group.
