Abstract
Transport network domains, including Optical Transport Network (OTN)
and Wavelength Division Multiplexing (WDM) networks, are typically
deployed based on a single vendor or technology platforms. They are
often managed using proprietary interfaces to dedicated Element
Management Systems (EMS), Network Management Systems (NMS) and
increasingly Software Defined Network (SDN) controllers.
A well-defined open interface to each domain management system or
controller is required for network operators to facilitate control
automation and orchestrate end-to-end services across multi-domain
networks. These functions may be enabled using standardized data
models (e.g. YANG), and appropriate protocol (e.g., RESTCONF).
This document analyses the applicability of the YANG models being
defined by the IETF (Traffic Engineering Architecture and Signaling
(TEAS) and Common Control and Measurement Plane (CCAMP) WGs in
particular) to support OTN single and multi-domain scenarios.
