An IPoDWDM Implementation Leveraging OpenROADM Standards for Enhanced Service Orchestration

This paper introduces an IP over Dense Wavelength Division Multiplexing (IPoDWDM) framework that integrates commercial state-of-the-art routing devices and Reconfigurable Optical Add-Drop Multiplexers (ROADMs), adhering to the OpenROADM MSA standards. A hierarchical software-defined networking controller (H-SDNC) seamlessly orchestrates network resource reservation across the DWDM aggregation layer and layer 2/3 through RESTCONF and NETCONF protocols. This first proof of concept paves the way for network architectures that closely integrate multi-layer resources to boost efficiency and flexibility in open and multi-vendor networks.
