Software-defined Optical Networking
Software defined networking (SDN) is an emerging technology that decouples network control from forwarding, making the network programmable to simplify management and enable fast provisioning. While SDN has traditionally considered small scale networks and higher-layer applications, our research focuses on extending SDN to large-scale optical networks and the fundamental photonic, WDM, SONET/SDH and OTN layers. From the optical core, to metro, access, datacenter, and mobile backhaul/fronthaul segments, we are leading the charge in software-defined optical networking through innovative network virtualization and programmability via OpenFlow-enabled control of all major optical elements, including adaptive optical amplifiers, flex-grid switching elements, and multi-degree transponders.
