An improvement of video streaming service using dynamic routing over OpenFlow networks

Network technology is being developed as a next-generation network (NGN) which is a software-defined networking. The network management can be done directly from the control unit that separated from the transmission unit, called as a forwarder and decoupling controller, which makes efficient network management. In the near future, the next generation network will be used to replace a traditional network. This paper presents a framework of Quality of Service (QoS) for improvement video streaming service on Mesh Topology via OpenFlow framework. We used the optimal dynamic routing to distribute the flow of data. Our framework has enhanced quality for transferring video streaming when many clients request at the same time. In simulation results, which show that our proposed the QoS dynamic routing framework can achieve significant improvement in overall quality of streaming more than none QoS scenarios. In additional, the performance to maintain the server is good for clients even the system reaches the critical point of the network.
