First Proof-of-Concept Demonstration of OpenFlow-Controlled Elastic Optical Networks Employing Flexible Transmitter/Receiver

In this paper, for the first time, the authors experimentally demonstrate an OpenFlow-controlled Elastic Optical Network (EON) employing a flexible transmitter/receiver. The flexible transmitter can switch the symbol rate and modulation format of the optical signal without modifying the hardware, and the flexible receiver can automatically detect different modulation formats and measure the Bit-Error Rate (BER) for light-path diagnosis. By using an OpenFlow-based control plane with significant protocol extensions, they successfully verify the seamless interworking between the control plane and all the network elements, and experimentally validate elastic path provisioning, dynamic service recovery and light-path restoration on an actual EON test-bed.
