A YANG Data Model for Optical Transport Network Topology
draft-ietf-ccamp-otn-topo-yang-12
Abstract
This document 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, 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 BCP 14 [RFC2119]
[RFC8174] when, and only when, they appear in all capitals, as shown
here.
Status of This Memo
This Internet-Draft is submitted in full conformance with the
provisions of BCP 78 and BCP 79.
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF). Note that other groups may also distribute
working documents as Internet-Drafts. The list of current Internet-
Drafts is at https://datatracker.ietf.org/drafts/current/.
Internet-Drafts are draft documents valid for a maximum of six months
and may be updated, replaced, or obsoleted by other documents at any
time. It is inappropriate to use Internet-Drafts as reference
material or to cite them other than as "work in progress."

1. Introduction
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 of equipments utilizing any of a
number of different transport technologies such as the Optical
Transport Networks (OTN) or packet transport such as provided by the
MPLS-Transport Profile (MPLS-TP).
