The traditional network was unable to manage the traffic in case of link failure. It takes too much time to change the affected devices in order to maintain the flow. It was time consuming and many questions have been raised on the efficiency. It’s quite difficult to manage the complex network and maintain pace with the increasing demands. Software Defined Network provides the architecture to manage the network without any change in the hardware but controlling through the software programming. Here the control and data plane is being separated to reduce the traffic with various protocols. Open-flow protocol is used for separation of control plane and data plane. Here the centralized controller is used to decide the forwarding of packets. This paper represents the brief review of SDN. The advantages and limitations of SDN have been discussed. Various simulation tools with supporting experimental analysis is being shown here.
