Design of IP Network Traffic Acquisition System Based on xFlow

摘要

Network traffic information is of great value to the monitoring and management of running network. It is of great importance to study the method of network traffic acquisition , understand and utilize the network effectively, monitor and analyze the network accurately. Based on the mature traffic acquisition methods proposed by previous scholars, this paper mainly conducts the research on xFlow network traffic information acquisition technology.The data sampling mechanism and interface sampling statistics of sFlow and Netflow are mainly studied.Then the simulation experiment environment is set up to verify the data acquisition and analysis, the network traffic information contained in the captured xFlow data has been effectively parsed, the validity and rationality of the network traffic acquisition method have been verified. The results show that based on the xFlow network traffic information acquisition method, the advantages of the two sampling methods are absorbed and the reliability of the sampling data is improved.
