面向软件定义网络的异常流量检测研究综述OA北大核心CSTPCD

Since software defined network(SDN)was more vulnerable to network attacks than traditional networks,the research progress of abnormal traffic detection for software defined network in recent years from the technical principle and architecture characteristics was summarized,the possible organizational forms of network attacks on SDN were ana-lyzed,and the characteristics,advantages,and disadvantages of current technologies related to abnormal traffic detection,abnormal traffic traceability,and abnormal traffic mitigation were discussed.The data sets commonly used in current re-search were compared and analyzed,and some general data preprocessing methods were sorted out.The research direc-tion of abnormal traffic detection methods in the SDN environment in the future was summarized and prospected.The research results can guide the selection of adaptation methods in practical application requirements,and the problems and contradictions to be solved can guide subsequent research.
