        Traffic Engineering (TE) and Service Mapping Yang Model
               draft-ietf-teas-te-service-mapping-yang-05

Abstract

   This document provides a YANG data model to map customer service
   models (e.g., the L3VPN Service Model (L3SM)) to Traffic Engineering
   (TE) models (e.g., the TE Tunnel or the Virtual Network (VN) model).
   This model is referred to as TE Service Mapping Model and is
   applicable generically to the operator's need for seamless control
   and management of their VPN services with TE tunnel support.

   The model is principally used to allow monitoring and diagnostics of
   the management systems to show how the service requests are mapped
   onto underlying network resource and TE models.
