一种资源占用统计最小的流分类方法研究

The Study of a flow classification mathod based on statistic minimizing resourse usage

本文通过分析流分类要达到的目标，得到了使边缘标记交换路由器资源占用统计最小的最佳分类门限，从而找到了流分类的科学度量准则。依据该推则和实测Ｉｎｔｅｒｎｅｔ流特性提出一种基于端口的改进Ｘ／Ｙ流分类方法，仿真和分析表明该方法较目前其它的数据驱动分类方法更加科学和完善。

An optimization classification threshold based on the principle of LER resource usage statistic minimization is obtained through analyzing the aim of flow classification. Thus the scientific measurement criterion is found as a result. A new improved X/Y classification method based on the principle and real Intemet flow character is raised in the paper. Both simulation and analysis prove this method is better than other data driven classitication methods present.
