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.

   This document lists the functional requirements toward OAM for DetNet
   domain.  The list can further be used for gap analysis of available
   OAM tools to identify possible enhancements of existing or whether
   new OAM tools are required to support proactive and on-demand path
   monitoring and service validation.  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].
