Abstract
This document specifies the Deterministic Networking MPLS data plane
when operating over an IEEE 802.1 Time-Sensitive Networking (TSN)
sub-network. This document does not define new procedures or
processes. Whenever this document makes statements or
recommendations, these are taken from normative text in the
referenced RFCs.

1. Introduction
Deterministic Networking (DetNet) is a service that can be offered by
a network to DetNet flows. DetNet provides these flows with low
packet loss rate and assured maximum end-to-end delivery latency.
General background and concepts of DetNet can be found in [RFC8655].
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
provide congestion protection (low loss, assured latency, and limited
reordering) leveraging MPLS Traffic Engineering mechanisms.
[RFC8964] specifies the DetNet data plane operation for MPLS-based
Packet Switched Network (PSN). MPLS encapsulated DetNet flows can be
carried over network technologies that can provide the DetNet
required level of service. This document focuses on the scenario
where MPLS (DetNet) nodes are interconnected by a IEEE 802.1 TSN sub-
