Mitigation of DDoS Attack in SDN Technology Using Load Balancing Policy

الملخص

Software Defined networking (SDN) is a new network technology that has been introduced to address the common issues in traditional networking. It provides central control by decoupling the control plane from network nodes and placing it in the controller. This allows the programmers to manage the entire network from one side. security issues, however, are challenging in this technology. There are many security issues in SDN networks, but Distributed Denial of Service (DDoS) is one of the biggest threats to SDN technology. This paper focuses on creating load balancing policy that can exploit the unutilized paths and use them for rerouting the packets in datacentres, we demonstrate how DDoS attack can exhaust the SDN network and provides the proper approach to deal with this attack in a short time. This method can be considered the first step to prevent the severe impact of attacks and alarm the system to block the attack ports.
