Emerging mega trends in Information and Communication Technology (ICT) and many Internet applications have offered new challenges to future Internet, of which dynamic management and high bandwidth rank high. High bandwidth needed for transporting huge data cannot be realized with traditional networking methods, wherein configurations of devices are carried out manually and capability of network infrastructure is not fully utilized. Software Defined Networking (SDN) is an emerging solution for such problems. In this article, we analyze the performance of SDN using its standard OpenFlow protocol by considering a scenario of medium enterprise data center. Performances of SDN are executed for parameters such as latency, packet delivery ratio and processing overhead in various topologies using simulations carried out in Mininet. Results indicate significant performance improvements of SDNs over traditional networks.
