Equal Cost Multi-path With Bit Indexed Explicit Replication

摘要

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. The node selects forwarding information based on a flow value associated with the packet. The forwarding information includes a forwarding bit mask. The node then forwards the packet based on the bit string and the forwarding information.

1. A method comprising:
receiving a packet at a node, wherein
the packet comprises a bit string; selecting a first set of forwarding information from a plurality of sets of forwarding information, wherein
the selecting is based on a flow value, andthe first set of forwarding information comprises a forwarding bit mask; and forwarding the packet based on the bit string and the first set forwarding information.
