DDoS Attack Monitoring using Smart Controller Placement in Software Defined Networking Architecture

Software defined networking is upcoming agile networking system for computer and telecommunication. The apartness of data plane and control plane are key points of SDN architecture which enables flexibility and programmability of network. But distributed denial of service attack is the main threat for software defined networking architecture as it can send huge traffic directly to the controller. In this paper, we proposed a hypothetical concept of smart controller placement for SDN architecture which can monitor controller's health status and provide continuous services during the DDoS attack.
