Evaluating a QoS aware path selection service using the GENI network

Smart homes, cars, offices and schools can significantly improve the quality of our life. The traditional networks are not sufficient to provide the service needed for these future smart management systems due to their lack of flexibility. This paper proposes an application-aware service that can select and set an alternative forwarding path based on the measurement of the Quality of Service of paths in the software defined networks. The proposed service is evaluated by developing experiments using the GENI network. The results demonstrate that our service can make routing decisions based on the application requirement and measurement about the current state of the network, and greatly improve the routing performance over the default method used in existing networks.
