    YANG Models for the Northbound Interface of a Transport Network
               Controller: Requirements and Gap Analysis
            draft-zhang-ccamp-transport-yang-gap-analysis-01

Abstract

   A transport network is a lower-layer network designed to provide
   connectivity services for a higher-layer network to carry the traffic
   opaquely across the lower-layer network resources.  A transport
   network may be constructed from equipment utilizing any of a number
   of different transport technologies such as the optical transport
   infrastructure (Synchronous Optical Networking (SONET) / Synchronous
   Digital Hierarchy (SDH) and Optical Transport Network (OTN)) or
   packet transport as epitomized by the MPLS Transport Profile (MPLS-
   TP).

   All transport networks have high benchmarks for reliability and
   operational simplicity.  This suggests a common, technology-
   independent management/control paradigm that can be extended to
   represent and configure specific technology attributes.

   This document describes the high-level requirements facing transport
   networks in order to provide open interfaces for resource
   programmability and control/management automation.  Furtheremore, gap
   analysis against existing models are also provided so that it can
   used as the guidance to separate efforts/drafts proposing new models
   or augmentation models based on existing models.
