DetNet Data Plane: MPLS over IP
draft-ietf-detnet-mpls-over-udp-ip-00
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 PseudoWires (PW) over IP.

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].
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
protection and reordering. The forwarding sub-layer is used to
provides congestion protection (low loss, assured latency, and
limited reordering) leveraging MPLS Traffic Engineering mechanisms.
This document specifies use of the MPLS DetNet encapsulation over an
IP network. The approach is modeled on the operation of MPLS and
PseudoWires (PW) over an IP Packet Switched Network (PSN)
[RFC3985][RFC4385][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 with full functionality at the DetNet layer over an
IP network, the following components are required (these are a subset
