Abstract Abstract
This document specifies a new architecture for the forwarding of This document specifies a new architecture for the forwarding of
multicast data packets. It provides optimal forwarding of multicast multicast data packets. It provides optimal forwarding of multicast
packets through a "multicast domain". However, it does not require a packets through a "multicast domain". However, it does not require a
protocol for explicitly building multicast distribution trees, nor protocol for explicitly building multicast distribution trees, nor
does it require intermediate nodes to maintain any per-flow state. does it require intermediate nodes to maintain any per-flow state.
This architecture is known as "Bit Index Explicit Replication" This architecture is known as "Bit Index Explicit Replication"
(BIER). When a multicast data packet enters the domain, the ingress (BIER). When a multicast data packet enters the domain, the ingress
