How does the implementation of software-defined networking (SDN) in enterprises affect network performance and reliability?
Best insight from top research papers
The implementation of software-defined networking (SDN) in enterprises has a significant impact on network performance and reliability. SDN allows for a centralized controller that separates the control plane and data plane, providing flexibility in network configuration and quick deployment . However, SDN is susceptible to security threats, such as Denial of Service (DoS) attacks, which can affect network performance . To address this, various security mechanisms and frameworks have been proposed to mitigate vulnerabilities and ensure network security . Additionally, SDN is more susceptible to controller resource exhaustion due to the rising frequency of distributed denial-of-service (DDoS) attacks, which can lead to network crashes and denial of access to authorized users . To overcome these challenges, approaches like traffic rate-based threshold (TRT) have been proposed to efficiently handle DDoS attacks and provide alternate paths for network traffic . Overall, the implementation of SDN in enterprises offers benefits in terms of network flexibility and management, but it also requires careful consideration of security measures to ensure reliable network performance .
