Transport Northbound Interface Applicability Statement
2018
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 IETF (TEAS and CCAMP
WGs in particular) to support OTN single and multi-domain scenarios.
