This video demonstrates OpenFlow integration between the HP VAN SDN Controller and Mininet. The HP Controller is an SDN controller that supports OpenFlow version 1.0 and 1.3. Mininet allows for easy learning and testing of and OpenFlow network emulated on a PC. This is similar in concept to GNS3 or HP Simware.
