1.  Introduction

   Deterministic Networking (DetNet) [I-D.ietf-detnet-architecture] is
   defined to provide high-quality network service with extremely low
   packet loss rate, bounded low latency and jitter.

   DetNet YANG [RFC7950] [RFC6991] models are used for DetNet service
   configuration, QoS configuration and topology discovery.  DetNet
   service and QoS configuration models are defined in
   [I-D.ietf-detnet-yang].  This document defines DetNet topology model
   that can be used for DetNet topology/capability discovery and device
   configuration.  DetNet topology model is an augmentation of the ietf-
   te-toplogy model [I-D.ietf-teas-yang-te-topo].

2.  Terminologies

   This document uses the terminologies defined in
   [I-D.ietf-detnet-architecture].

3.  DetNet Topology Model

   A DetNet topology is composed of a set of DetNet nodes and DetNet
   links.  DetNet nodes represent the network devices that can transport
