Motivation of DDoS Attack-Aware in Software Defined Networking Controller Placement

Software Defined Networking (SDN) is on strike around the world. Many scientists, researcher, IT and telecommunication professionals are focusing on it. SDN is the upcoming superb, centralized, cost-effective, programmable and agile future networking system. As the current computer networks are complicated and difficult to superintend we need SDN to make the network and telecommunication services fruitful, flexible, yieldable, strengthen and secured. Distributed Denial of Service Attacks (DDoS) attack is the main thread for upcoming SDN. In this paper we are going to investigate on DDoS attack propagation model in SDN, DDoS attack-aware controller placement and the possible DDoS attack on SDN functional architecture. After that we will present our controller placement model to reduce DDoS attack. This research work can boost understanding on how to reduce or avoid SDN itself from behooving a prey of DDoS attacks.
