Abstract Abstract
Bit Index Explicit Replication (BIER) is an architecture that Bit Index Explicit Replication (BIER) is an architecture that
provides optimal multicast forwarding through a "BIER domain" without provides optimal multicast forwarding through a "BIER domain" without
requiring intermediate routers to maintain any multicast related per- requiring intermediate routers to maintain any multicast related per-
flow state. BIER also does not require any explicit tree-building flow state. BIER also does not require any explicit tree-building
protocol for its operation. A multicast data packet enters a BIER protocol for its operation. A multicast data packet enters a BIER
domain at a "Bit-Forwarding Ingress Router" (BFIR), and leaves the domain at a "Bit-Forwarding Ingress Router" (BFIR), and leaves the
BIER domain at one or more "Bit-Forwarding Egress Routers" (BFERs). BIER domain at one or more "Bit-Forwarding Egress Routers" (BFERs).
