1.  Introduction

   [Editor's note: Introduction to be made specific to DetNet IP over
   TSN scenario.  May be similar to intro of DetNet MPLS over TSN.].

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

   This document specifies the DetNet data plane operation for IP hosts
   and routers that provide DetNet service to IP encapsulated data.  No
   DetNet specific encapsulation is defined to support IP flows, rather
   existing IP and higher layer protocol header information is used to
   support flow identification and DetNet service delivery.

   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
