                  DetNet Data Plane: MPLS over UDP/IP
                 draft-ietf-detnet-mpls-over-udp-ip-01

Abstract

   This document specifies the MPLS Deterministic Networking data plane
   operation and encapsulation over an IP network.  The approach is
   modeled on the operation of MPLS and over UDP/IP packet switched
   networks.

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].

   This document specifies use of the MPLS DetNet encapsulation over an
   IP network.  The approach is modeled on the operation of MPLS over an
   IP Packet Switched Network (PSN) [RFC7510].  It maps the MPLS data
   plane encapsulation described in [I-D.ietf-detnet-mpls] to the DetNet
   IP data plane defined in [I-D.ietf-detnet-ip].

   To carry DetNet flows with full functionality at the DetNet layer
   over an IP network, the following components are required (these are
   a subset of the requirements for MPLS encapsulation listed in
   [I-D.ietf-detnet-mpls]):

   1.  A method of identifying the DetNet flow group to the processing
       element.

   2.  A method of carrying the DetNet sequence number.
