Abstract

   This document specifies Deterministic Networking data plane operation
   over an IP network.  It is primarily aimed at IPv4, but would work
   with IPv6 as well if a unified solution is desired.

   This document is a derivative work from draft-ietf-detnet-dp-sol-01,
   to augment or replace the text currently contained in section 5.2.2.

   Whether this is published as a stand-alone text, or serves as a focal
   point to refine the IP design and subsequently remerged with draft-
   ietf-detnet-dp-sol-01 is a matter for the DETNET WG.

1.  Introduction

   This document is a derivative work from [I-D.ietf-detnet-dp-sol].

   Whether this is published as a stand-alone text, or serves as a focal
   point to refine the IP design and subsequently remerged with draft-
   ietf-detnet-dp-sol-01 is a matter for the DetNet WG.

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

   This document specifies the encapsulation and operation of
   deterministic networking over an IP data-plane.  The approach is
   modeled on the operation of PseudoWires (PW) over an IP Packet
   Switched Network (PSN) [RFC3985][RFC4385][RFC7510].

   It is based on the "simplified model" discussed during the DetNet
   Interim Meeting held on 14 February 2018
