摘要： In one embodiment, for each particular multicast flow of a plurality of multicast flows of packets a particular consolidation encoding of a plurality of consolidation encodings is selected based on the sparseness of bit positions within a bit string corresponding to designated receiving packet switching devices of the particular multicast flow. The packet switching device sends one or more packets corresponding to said particular packet, with each of these one or more packets including designated receiving packet switching devices of the particular multicast flow in the header of said particular packet according to the particular consolidation encoding. In one embodiment, different consolidation encodings of the plurality of consolidation encodings are used for at least two different multicast flows of the plurality of multicast flows of packets. In one embodiment, each of said receiving packet switching devices is Bit Index Explicit Replication (BIER) Bit-Forwarding Router (BFR).

摘要： In one embodiment, a provider edge packet switching device of a provider network is configured with different Internet Protocol (IP) forwarding information bases (FIBs) depending on whether the forwarding information base is associated with core-facing ingress packet traffic (e.g., packet traffic from the provider network) or customer-facing ingress packet traffic (e.g., packet traffic from a customer network). In the latter case of customer-facing ingress packet traffic, the customer-facing forwarding information base includes load balancing lookup results for load balancing traffic between a customer edge packet switching device and through the provider network. In the case of core-facing ingress packet traffic, the core-facing forwarding information base includes a lookup result for forwarding traffic to a customer edge packet switching device, and does not include the above-referenced load balancing lookup result information.
