Mitigating Flow Table Overloading Attack with Controller-based Flow Filtering Strategy in SDN

摘要: Controller is a key component in the three layers of Software - Defined Networking (SDN), which to process huge number flow requests from network devices. As result, it puts rule into table switch according every incoming packet. However, capacity limited and can be target malicious attacks by taking advantage installing rules controller. Specifically, pushed controller occupy available space for new benign traffic due controlling directing packets SDN relied on installation. These tables full massive entries populated controller, leading out flows. This paper gives method mitigate overloading attack after DDoS notification. It help data plane more secured improving availability with strategy real-time packet monitoring management
