| 摘 要： | 通过对现有流超时策略进行比较和分析,指出适用范围和存在的问题。针对单包流占总体流量很大比例的特点,提出了两层自适应超时策略(TSAT)。通过对不同特性的流采用不同的超时方式,增加网络测量性能,提高了测量系统的资源利用率。最后通过实验论证文章提出的超时策略在实际测量中的性能,并进一步分析适用范围。

| Abstract: | Firstly discussed the state-of-art of flow timeout strategies, and pointed out where they were applicable and their shortcomings. Presented a two-level self-adaptive timeout (TSAT) strategy which handles flows with different timeout strategy according to its feature. This method could improve the performances of network measurement and the efficiency of the resource usage of measurement systems. Some experiments were employed to show the rationality of TSAT strategy. Then the fitness area of strategy was anatomized as well. |
