Demonstration of an OpenROADM SDN-Enabled Network for Geo-Distributed Data Centers

This paper describes an integrated system consisting of three domains (or layers): a Wavelength Division Multiplexing (WDM) optical domain, an Ethernet packet switching domain, and a data center compute domain. The resources across the three domains are managed by a single orchestrator software module through the use of standard interfaces based on OpenROADM, OpenFlow, and OpenStack, respectively. A demonstration consisting of OpenROADM-certified optical equipment from two vendors, OpenFlow commercial switches, and repurposed Stampede compute nodes is also reported.
