Simulation of DOS Attacks Mitigation in Software Defined Network Architecture using Load Balancing Algorithm

This research investigates the revolutionary influence of Software Defined Networks (SDNs) on traditional network architectures, focusing particularly on their role in mitigating Denial of Service (DoS) attacks. Conventional network setups involve intermediary devices managing both control and data planes, directing network packets. SDNs, however, centralize control functions onto dedicated controllers, effectively segregating control and data planes within network devices. DDoS attacks, orchestrated by distributed networks of compromised computers, aim to disrupt network resources, resulting in abnormal behavior and system incapacitation. This study employs network simulation utilizing SDN technology to evaluate parameters such as CPU load, traffic distribution, and server connections during DoS attacks. The findings suggest that leveraging the SDN Controller for load balancing can enhance the reliability of networks facing DoS attacks. Increased server deployment for managing the attack correlates with reduced packet losses, thus improving the overall reliability of the service provided.
