Study on NetFlow-based network traffic data collection and storage
Tongge Xu · Jisuanji yingyong yanjiu · 2008
A network traffic data collection and storage solution based on NetFlow was presented,which was used to solve the problem of large traffic data analysis caused by high-speed network.By using multi-thread programming technique and double-lists cache structure,the efficiency and dependability of NetFlow data collection could be enhanced.Furthermore,a three-le-vel aggregation and storage method based on the original NetFlow data was designed.By this method,the original flows could be sorted and simplified in order to offer a reasonable and efficient data support to the front static and dynamic analysis application.
