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.
