    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 bit string includes information identifying a plurality of destinations. The node selects an entry in a bit indexed forwarding table (BIFT). The BIFT includes both a primary path entry and a backup path entry. The node forwards the packet based on information in the entry.

    Abstract: Methods, devices and program instructions are disclosed for performing bit indexed explicit replication (BIER) including fast reroute capability. One embodiment of a method includes receiving, from an egress node of a BIER network, an advertisement at a forwarding node, where the advertisement identifies a mapping of the egress node to a bit position of a packet bit string to be carried by a packet through the network. The embodiment further includes generating or updating a primary entry for the egress node in a bit indexed routing table (BIRT) for the forwarding node, and determining whether a backup entry for the egress node is to be included in the BIRT. In response to a determination that a backup entry is to be included, the embodiment further includes generating or updating the backup entry in the BIRT.

    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.

    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.
