    abstract =  {This document defines a YANG model for managing dynamic Optical networks, including Wavelength Switched Optical Networks (WSON) and Flexi-Grid DWDM Networks. The model described in this document is composed of two submodels: one to define an optical traffic engineering database, and other one to describe the optical paths or media channels.},
