Performance Analysis of DDoS Attack in SDN Network

Software Defined network is one of the emerging technology which enhances the working of network by merging the concept of networking with software, where network is manageable by means of software. This technology changes the way of working of networking at a glance. Security is one of the issue with any networking technology as a single intrusion may cost the entire network. Distributed denial-of-service is one of the security issue which attack the system and hampered the normal working of the system. This paper discusses about security within software defined network taking the case of denial of service attack and discuss how Denial of service attack affects the performance of the software defined network taking parameter of entropy for measuring the performance of software defined network.
