摘要
Flow-based measurement is a popular method for various network monitoring usages. However, many flow exporting softwares have still low performance to collect all flows. In this paper, we propose a IPFIX-based flow export engine with an enhanced and extensible data structure, called XFix, on the basis of a GPL tool, -nProbe. In the engine, we use an extensible two-dimensional hash table for flow aggregation, which is able to improve the performance of the metering process as well as support bidirectional flow. Experimental results have shown its efficiency in multi-thread processing activity.
