                 draft-ietf-detnet-mpls-over-udp-ip-07

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].

   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.

   3.  A method for distinguishing DetNet OAM packets from DetNet data
       packets.

   4.  A method for carrying queuing and forwarding indication.

   These requirements are satisfied by the DetNet over MPLS
   Encapsulation described in [I-D.ietf-detnet-mpls] and they are partly
   satisfied (i.e., IP flows can be identified however no DetNet
