              A Yang Data Model for IETF Network Slice NBI
              draft-wd-teas-ietf-network-slice-nbi-yang-01

Abstract

   This document provides a YANG data model for the IETF Network Slice
   NBI (Northbound Interface).  The model can be used by a higher level
   system which is the IETF Network Slice consumer of an IETF Network
   Slice Controller (NSC) to request, configure, and manage the
   components of an IETF Network Slice.

   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 IETF
   Network Slice NBI.

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