Abstract
Today’s networks are quite static, dedicated to single services and slow to change. With the increasing demands of users the traditional network is lacking the ability to fulfill the requirements. These users are business and application. Software Defined Networking(SDN) is the answer to these problems. SDN network allow dynamic handling of numbers allowing multiple users to share one common infrastructure for both carriers and services providers . SDN will give a new direction to the networking world. In this paper the description of limitations of traditional network is given, which led formation of SDN paradigm. The objective of this paper is to look at the research opportunities and challenges for SDN. This paper give a review of what is SDN, its need, architecture, implementation and more important the applications of SDN.
