Reconfigurable virtual data centre networks based on openflow-enabled OPS

We demonstrate a reconfigurable virtual data centre network by utilizing scalable and flow-controlled optical packet switching system. Flexible virtual network reconfiguration conducted by the centralized SDN controller is decoupled from the sub-microsecond hardware switching time scale. OpenFlow messages enabling control communication between SDN controller and OPS switch are validated. Results show QoS could be guaranteed by priority assignment and load balancing for applications in virtual networks.
