SOFTWARE DEFINED NETWORKING A Literature Review Presented to Prof. Sharmin Khan Department of Computer Science San Jose State University In Partial Fulfillment Of the Requirements for the class CS200W By Hina Mohare April 2016 ABSTRACT Software Defined Networking (SDN) is a rapidly growing technology which has received lot of attention. It addresses some of the long-standing challenges in the field of computer networks. It simplifies and makes it easier to management network. The core idea behind SDN is to pull out the intelligence from network devices like switch and router so that entire network can be controlled from a centralized single controller. The SDN controller has the global view of entire network devices. The controller can be customized by the network administrators or by the engineers as per the need of the business. The SDN technology makes the network programmable, agile, dynamic, scalable, flexible and centrally controlled. This paper initially focuses on the need of SDN. In the later part consists of architecture of the SDN enabled network, its different applications, challenges in implementing SDN. Table of Contents 1. Introduction 1 2. Need of SDN 4 3.
