Abstract
This document provides an analysis of the applicability of the YANG
models defined by the IETF (Traffic Engineering Architecture and
Signaling (TEAS) moreover, Common Control and Measurement Plane
(CCAMP) WGs in particular) to support ODU transit services,
Transparent client services and EPL/EVPL Ethernet services over OTN
single and multi-domain network scenarios.
This document also describes how existing YANG models can be used
through a number of worked examples and JSON fragments.
