1.  Introduction

   [I-D.ietf-detnet-architecture] 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 to 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.
