Unprecedented Smart Algorithm for Uninterrupted SDN Services During DDoS Attack

In the design and planning of next-generation Internet Things (IoT), telecommunication, satellite communication systems, controller placement is crucial in software-defined networking (SDN). The programmability SDN sophisticated for centralized control system entire network. Nevertheless, it creates a significant loophole manifestation distributed denial service (DDoS) attack straightforwardly. Furthermore, recently Distributed Reflected Denial Service (DRDoS) attack, an unusual DDoS has been detected. However, minimal deliberation given to this forthcoming single point infrastructure failure problem. Moreover, high frequencies attacks have increased dramatically. paper, smart algorithm backup controllers under scenarios proposed. Our proposed can recommend or multiple event occurrence. obtained simulated results demonstrate that validation performance analysis achieved 99.99% accuracy placing within 0.125 46508.7 s SDN.
