Abstract Abstract
Bit Index Explicit Replication (BIER) is an architecture that Bit Index Explicit Replication (BIER) is an architecture that
provides multicast forwarding through a "BIER domain" without provides multicast forwarding through a "BIER domain" without
requiring intermediate routers to maintain multicast related per-flow requiring intermediate routers to maintain multicast related per-flow
state. Neither does BIER require an explicit tree-building protocol state. Neither does BIER require an explicit tree-building protocol
for its operation. A multicast data packet enters a BIER domain at a for its operation. A multicast data packet enters a BIER domain at a
"Bit-Forwarding Ingress Router" (BFIR), and leaves the BIER domain at "Bit-Forwarding Ingress Router" (BFIR), and leaves the BIER domain at
one or more "Bit-Forwarding Egress Routers" (BFERs). The BFIR router one or more "Bit-Forwarding Egress Routers" (BFERs). The BFIR router
