Abstract
System and method for performance-based routing in an SDN. An SDN controller is configured to adaptively determine data transmission routes based on real-time route performance evaluation provided by a virtual router. The virtual router includes a route detection component to attain route performance data and a performance evaluation component to evaluate the route performance based on predetermined criteria provided by the SDN controller. The evaluation result is sent to the SDN controller and used to intelligently determine a superior route selection and route usage for a specific application program. According to the determination, the SDN controller updates the flow table associated with the virtual router for subsequent data transmission.
