Abstract:
Disclosed is a method that modifies a bit indexed explicit replication (BIER) algorithm. The method includes receiving a packet at a node, wherein the packet includes a BIER header identifying a bitstring, the bitstring including a first bit indicating a first destination and a second bit indicating a second destination and forwarding the packet through one or more networks toward the first destination and the second destination based on the bitstring and a predetermined bit selection order. The predetermined bit selection order causes a sequential delivery of the packet to the first destination and the second destination. After the packet arrives at the first destination, the method includes setting the first bit to zero in the bitstring and forwarding the packet through the one or more networks toward the second destination according to the updated bitstring.
