Towards OpenFlow based software defined networks

Software defined networks (SDN) are an emerging technology that is being increasingly adopted by various network operators. These technologies provide new services and powerful analytics that help to transform the network and unfasten its intelligence to serve today's business demands. This paper briefs about the need for change in the current networking technology and explores the role of Open Flow protocol that is used by researchers to experiment with more realistic settings to provide for a new network architecture. Further, this paper discusses the advantages offered by SDN and the huge potential of OpenFlow based SDN. As SDN can simplify management of virtualized networks, enable cloud computing and reduce costs, the vendors would be encouraged to adopt SDN and OpenFlow. The objective of this paper is to provide an insight into the latest technology to the vendors to assist them in future enhancement of their switch products in the network.
