               A Yang Data Model for Transport Slice NBI
                 draft-wd-teas-transport-slice-yang-02

Abstract

   This document provides a YANG data model for the Transport Slice NBI.
   The model can be used by a higher level system which is the Transport
   slice consumer of a Transport Slice Controller (TSC) to request,
   configure, and manage the components of a transport slices.

   The YANG modules in this document conforms to the Network Management
   Datastore Architecture (NMDA) defined in RFC 8342.

1.  Introduction

   This document provides a YANG [RFC7950] data model for the transport
   Slice NBI.

   The YANG model discussed in this document is defined based on the
   description of the transport slice in
   [I-D.nsdt-teas-transport-slice-definition] and
   [I-D.nsdt-teas-ns-framework], which is used to operate customer-
   driven Transport Slice during the Transport Slice instantiation, and
   the operations includes modification, deletion, and monitoring.

   The YANG model discussed in this document describes the requirements
   of a Transport Slice that interconnects a set of Transport Slice
