        A YANG Data Model for Optical Transport Network Topology
                   draft-ietf-ccamp-otn-topo-yang-00

Abstract

   A transport network is a server-layer network designed to provide
   connectivity services for a client-layer network to carry the client
   traffic transparently across the server-layer network resources.  A
   transport network can be constructed from equipments utilizing any of
   a number of different transport technologies such as the evolving
   Optical Transport Networks (OTN) or packet transport as provided by
   the MPLS-Transport Profile (MPLS-TP).

   This draft describes a YANG data model to describe the topologies of
   an Optical Transport Network (OTN).  It is independent of control
   plane protocols and captures topological and resource related
   information pertaining to OTN.  This model enables clients, which
   interact with a transport domain controller via a REST interface, for
   OTN topology related operations such as obtaining the relevant
   topology resource information.

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].
