In 2023 and 2024, several comprehensive surveys have been conducted on DDoS detection and mitigation strategies within Software-Defined Networks (SDNs). These surveys address the evolving landscape of SDN security, focusing on both high-rate and low-rate DDoS attacks.

One notable survey from **Cluster Computing** provides an extensive overview of existing DDoS detection, mitigation, and defense mechanisms in SDNs. It categorizes various approaches, highlighting their effectiveness and the ongoing challenges in developing robust DDoS protection strategies for SDN environments【8†source】.

Another significant study in **Multimedia Tools and Applications** explores the taxonomy of DDoS defense mechanisms in SDNs, identifying key research challenges and opportunities. It emphasizes the need for adaptive and intelligent systems that can respond to the dynamic nature of DDoS attacks【9†source】.

Furthermore, an article in **IEEE Access** published in 2024 offers a detailed examination of DDoS detection methods specifically tailored for SDNs. This study highlights recent advancements and future directions, providing a crucial resource for researchers looking to enhance security within SDN architectures【10†source】.

These surveys collectively underline the importance of continuous innovation in DDoS detection and mitigation techniques to address the complexities introduced by SDNs.
