Terabit elastic optical networking (EON) is foreseen as a viable solution to extend the lifetime of a network exploiting the available bandwidth in previously deployed optical fibers. EON is based on bandwidth-variable transponders capable of supporting multiple bit rates and/ or modulation formats according to traffic requirements and node architectures… (More)
This paper presents an Optical SDN architecture and implementation enabled for virtual optical networks, supporting adaptive and cognitive algorithms to enhance QoT. The paper also shows experimental results of a software-defined autonomic flexible transponder.
Experimental platforms are essential to demonstrate the potential benefits that Software Defined Networking (SDN) can bring to optical metro and backbone carriers' infrastructure. In this context, the Autonomous Network (AN) project is an SDN-enabled five-node metropolitan optical network test-bed located at CPqD. The AN main objective is to bring novel SDN… (More)
