Bit Indexed Explicit Replication (BIER) is a novel multicast forwarding scheme for IP networks that avoids states in replicating routers by encoding the multicast information into a bit string in the packet header. In addition, the BIER-TE variant encodes the multicast tree in the header and allows for network programmability. We propose the use of maximally redundant trees (MRTs) for 1+1 protection in BIER that currently lacks this feature. We further discuss three different fast reroute (FRR) protection schemes for BIER-TE we have proposed in the Internet Engineering Task Force (IETF). They use header modification only (HM), rely on point-to-point tunnels (PPT), or leverage BIER-in-BIER encapsulation (BBE). We compare them regarding protection coverage, path lengths, traffic loads, required network capacity, state requirements and overhead in a large number of networks. The results serve the discussions in IETF where BIER and BIER-TE are currently standardized. |
