                 A Yang Data Model for Transport Slice
                 draft-wd-teas-transport-slice-yang-00

Abstract

   This document provides a YANG data model for the transport slice
   service.  The model can be used by a client management system of the
   transport slice controller to request, configure, and manage the
   components of an transport slice service.

   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 transport Slice
   Service.

   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 is used to operate
   customer-driven transport Slice during the transport Slice Network
   instantiation, and the operations includes service creation,
   modification, deletion, and monitoring.

   The YANG model discussed in this document suggests an abstract,
   technology independent model, which includes three major constructs:

   o  Transport Slice(TS): that describe a logical network that
      interconnects Transport Slice End Points.

   o  Ts-Endpoint: is a logical point at an external interface of a
      Transport slice network, to which a particular subset of traffic
      that traverse the external interface, and the traffic is mapped to
      a specific transport slice.
