Scaling BIER-TE to Large Networks with Subset Tunneling and Resilient Forwarding
The authors propose architectural extensions to scale BIER-TE, a stateless multicast transport protocol, to large networks while supporting resilient communications. The key idea is to subdivide the BIER domain into 2-connected subsets and leverage tunneling, egress protection, and modified BIER-TE-FRR to enable scalable and resilient forwarding.
