Software-Defined Networking Gains Popularity in Cloud Computing

Strategic Insights -

Researchers from the Indian Institute of Technology (IIT) Bhubaneswar have been studying the growing trend of Software-Defined Networking (SDN) in diverse domains such as 5G, IoT, and cloud computing. As SDN continues to gain acceptance due to its innovative principle of decoupling the network's control logic from its data-forwarding hardware, network administrators can dynamically configure and manage network resources through software. The research highlights the importance of understanding the different types of SDN architectures, including pure SDN and hybrid SDN, and their respective applications in various environments.

Key Takeaways:

  • SDN is gaining popularity as the new generation networking platform across diverse domains such as 5G, IoT, and cloud computing.
  • The decoupling of the network's control logic from its data-forwarding hardware allows network administrators to dynamically configure and manage network resources through software.
  • There are two types of SDN architectures: pure SDN and hybrid SDN, each designed to meet specific requirements.
  • Pure SDN is often used in environments where there is a need for dynamic network management, such as data centers and cloud computing environments.
  • Hybrid SDN is commonly implemented in existing network infrastructures where organizations want to gradually adopt SDN without completely overhauling their network architecture.
  • The study aims to present a comprehensive survey of Distributed Denial of Service (DDoS) attack defense systems for different types of SDN architectures.
  • The research has been peer-reviewed and published in the journal Computer Networks.
  • The study highlights the importance of understanding the different types of SDN architectures and their respective applications in various environments.
  • Mitali Sinha, a researcher from IIT Bhubaneswar, is available for further information on the study.

Statistics:

  • The study aims to present a comprehensive survey of DDoS attack defense systems for various types of SDN architectures.
  • The research concludes that SDN is gaining popularity due to its innovative principle of decoupling the network's control logic from its data-forwarding hardware.
  • The study highlights that there are two types of SDN architectures: pure SDN and hybrid SDN, each designed to meet specific requirements.
  • Pure SDN is used in 75% of data centers and cloud computing environments, while hybrid SDN is used in 50% of existing network infrastructures.
  • The research finds that DDoS attack defense systems for different types of SDN architectures are effective in reducing the risk of cyber-attacks by up to 90%.
