1. Introduction
[Editor's note: Introduction to be made specific to TSN over DetNet
scenario. Do we intend to cover both TSN over DetNet IP and TSN over
DetNet MPLS? Or this document is limited to MPLS scenarios?].
2. Terminology
[Editor's note: text to be review what is really needed here.].
2.1. Terms Used in This Document
This document uses the terminology established in the DetNet
architecture [I-D.ietf-detnet-architecture], and the reader is
assumed to be familiar with that document and its terminology.
The following terminology is introduced in this document:
