Xperience of Programmable Network with OpenFlow

Abstract

Abstract-Today in the era of fast, modern and continuous changing world, we 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 us 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, we have demonstrated to run a network topology on OpenFlow Virtual Machine Simulator (VMS) using NOX controller. Monitoring of flow tables on various switches has been analyzed. Later, we have developed a number of NOX controller components using C++ code to restrict Address resolution Protocol (ARP) on our network and to define dynamic programmable flows on OpenFlow switches.
