Dear All,
yet another technical refresh of the essential BIER OAM document. Please
let me know if you have any concerns that must be resolved before this work
can be progressed further (AFAICS, it is still in WF LC),

Regards,
Greg (on behalf of the authors)

   Title:   BIER Ping and Trace

Abstract:

   Bit Index Explicit Replication (BIER) is an architecture that
   provides optimal multicast forwarding through a "BIER domain" without
   requiring intermediate routers to maintain any multicast-related per-
   flow state.  BIER also does not require any explicit tree-building
   protocol for its operation.  A multicast data packet enters a BIER
   domain at a "Bit-Forwarding Ingress Router" (BFIR), and leaves the
   BIER domain at one or more "Bit-Forwarding Egress Routers" (BFERs).
   The BFIR router adds a BIER header to the packet.  The BIER header
   contains a bit-string in which each bit represents exactly one BFER
   to forward the packet to.  The set of BFERs to which the multicast
   packet needs to be forwarded is expressed by setting the bits that
   correspond to those routers in the BIER header.

   This document describes the mechanism and basic BIER OAM packet
   format that can be used to perform failure detection and isolation on
   the BIER data plane.
