   Operations, Administration and Maintenance (OAM) for Deterministic
                 Networks (DetNet) with MPLS Data Plane
                     draft-ietf-detnet-mpls-oam-02

Abstract

   This document defines format and use principals of the Deterministic
   Network (DetNet) service Associated Channel (ACH) over a DetNet
   network with the MPLS data plane.  The DetNet service ACH can be used
   to carry test packets of active Operations, Administration, and
   Maintenance protocols that are used to detect DetNet failures and
   measure performance metrics.

1.  Introduction

   [RFC8655] introduces and explains Deterministic Networks (DetNet)
   architecture and how the Packet Replication and Elimination function
   (PREF) can be used to ensure low packet drop ratio in DetNet domain.

   Operations, Administration and Maintenance (OAM) protocols are used
   to detect, localize defects in the network, and monitor network
   performance.  Some OAM functions, e.g., failure detection, work in
   the network proactively, while others, e.g., defect localization,
   usually performed on-demand.  These tasks achieved by a combination
   of active and hybrid, as defined in [RFC7799], OAM methods.

   Also, this document defines format and use principals of the DetNet
   service Associated Channel over a DetNet network with the MPLS data
   plane [I-D.ietf-detnet-mpls].
