DetNet Data Plane: MPLS over UDP/IP
draft-ietf-detnet-mpls-over-udp-ip-03
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.
