1.  Introduction

   The Time-Sensitive Networking Task Group (TSN TG) within IEEE 802.1
   Working Group deals with deterministic services through IEEE 802
   networks.  Deterministic Networking (DetNet) defined by IETF is a
   service that can be offered by a L3 network to DetNet flows.  General
   background and concepts of DetNet can be found in
   [I-D.ietf-detnet-architecture].

   This document specifies the use of a DetNet MPLS network to
   interconnect TSN nodes/network segments.  DetNet MPLS data plane is
   defined in [I-D.ietf-detnet-mpls].
