The Internet is one of the great technology success stories of the twentieth century. It has enabled greater access to information, provided new modes of communication among people and organizations and has fundamentally changed the way we work, play and learn. It has bought the entire world under a single roof. Unfortunately, the Internet’s very success is now creating obstacles to innovation in the networking technology that lies at its core and the services that use it. The size and scope of the public Internet now make the introduction and deployment of new network technologies and advanced services difficult. While the research community has developed innovative solutions to a wide range of networking challenges, there has been remarkably little progress towards deploying these capabilities in the Internet at large. The ossification of the Internet is a natural evolutionary stage in the development of any highly successful technology. To some extent these problems are addressed by network virtualization, but because of the overhead involved causing hindrance to the growth of technology. To address these issues the concept of programmable networking was introduced. Software defined networking is one such programmable networking technology which aim to provide network as a service like any other resources such as computing and storage. Because of its dynamism in implementing new network protocols and configuration of network it as gained a very popularity in less time.
