Today in the era of fast, modern and continuous changing world, the authors need to enhance and improve the existing routing and switching protocols for better performance. OpenFlow switches enable researchers to test and examine the behavior of newly designed protocol in their local environment without disturbing the existing production flow. This allows them to provide the minimize delay in production packet forwarding and maximum flexibility in controlling the flow of experimental packets through the network. In this paper, they have demonstrated to run a network topology on OpenFlow Virtual Machine Simulator (VMS) using NOX controller.
