MHSDN: A Hierarchical Software Defined Network Reliability Framework design

At present, attacks based on the vulnerability of controller and flooding still constitute a principal threat for hierarchical Software Defined Network (SDN), such as flow table tampering, malicious Application attacks, Distributed Denial Service (DDoS) etc., due to limitation against known or unknown vulnerabilities traditional cyber defence technology. Therefore, this study proposes an active architecture Mimic Defence (MD)–Mimic Hierarchical SDN Framework (MHSDN). Then endogenous security MHSDN is theoretically analysed. Simultaneously, attack surface measurement MD innovatively proposed, further improving usability standards system. Finally, speed up detection reduce cost DDoS, research Random Forest Feature Extract (RFFE) tolerable switch migration. Simulation shows that RFFE has achieved faster at less accuracy, can better improve reliability SDN.
