1. Introduction
The Time-Sensitive Networking Task Group (TSN TG) within IEEE 802.1
Working Group deals with deterministic services through IEEE 802
networks. Deterministic Networking (DetNet) defined by IETF is a
service that can be offered by a L3 network to DetNet flows. General
background and concepts of DetNet can be found in [RFC8655].
This document specifies the use of a DetNet MPLS network to
interconnect TSN nodes/network segments. DetNet MPLS data plane is
defined in [I-D.ietf-detnet-mpls].
