             BIER-TE-based OAM, Replication and Elimination
             draft-thubert-bier-replication-elimination-01

Abstract

   This specification leverages Bit Index Explicit Replication - Traffic
   Engineering to control in the data plane the DetNet Replication and
   Elimination activities, and to provide traceability on links where
   replication and loss happen, in a manner that is abstract to the
   forwarding information.

1.  Introduction

   Deterministic Networking (DetNet) [I-D.ietf-detnet-problem-statement]
   provides a capability to carry unicast or multicast data flows for
   real-time applications with extremely low data loss rates and known
   upper bound maximum latency [I-D.ietf-detnet-architecture].

   DetNet applies to multiple environments where there is a desire to
   replace a point to point serial cable or a multidrop bus by a
   switched or routed infrastucture, in order to scale, lower costs, and
   simplify management.  One classical use case is found in particular
   in the context of the convergence of IT with Operational Technology
   (OT), also referred to as the Industrial Internet.  But there are
   many others use cases [I-D.ietf-detnet-use-cases], for instance in in
   professional audio and video, automotive, radio fronthauls, etc..

   The DetNet data plane alternatives [I-D.dt-detnet-dp-alt] studies the
   applicability of existing and emerging dataplane techniques that can
   be leveraged to enable DetNet properties in IP networks.  One
   critical feature in the dataplane is traceability, the capability to
   control the activity of intermediate nodes on a packet.  For
   instance, if Replication and Elimination is applied to a packet, then
   it is desirable to determine which node performed a certain copy of
