Traffic Engineering (TE) and Service Mapping Yang Model
draft-ietf-teas-te-service-mapping-yang-03
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.
