                 draft-ietf-detnet-mpls-over-udp-ip-04

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 extremely low
   packet loss rates and assured maximum end-to-end delivery latency.
   General background and concepts of DetNet can be found in [RFC8655].

   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 MPLS 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 for identifying DetNet flows to the processing element.

   2.  A method for carrying the DetNet sequence number.
