1.  Introduction

   Deterministic Networking (DetNet) is a service that can be offered by
   a network to DetNet flows.  DetNet provides these flows with a low
   packet loss rates and assured maximum end-to-end delivery latency.
   General background and concepts of DetNet can be found in
   [I-D.ietf-detnet-architecture].

   The DetNet Architecture decomposes the DetNet related data plane
   functions into two sub-layers: a service sub-layer and a forwarding
   sub-layer.  The service sub-layer is used to provide DetNet service
   protection and reordering.  The forwarding sub-layer is used to
   provides congestion protection (low loss, assured latency, and
   limited reordering) leveraging MPLS Traffic Engineering mechanisms.

   [I-D.ietf-detnet-mpls] specifies the DetNet data plane operation for
   MPLS-based Packet Switched Network (PSN).  MPLS encapsulated DetNet
   flows can be carried over network technologies that can provide the
   DetNet required level of service.  This document focuses on the
   scenario where MPLS (DetNet) nodes are interconnected by a IEEE 802.1
   TSN sub-network.
