| 摘 要： | 通过对测量间隔为10ms的Internet路径往返延迟测量数据的分析，发现了往返延迟呈现两类截然不同的特性：突发态特性和平稳态特性。通过DFA分析，进一步得出以下结论：Internet路径往返延迟序列不具有单一的标度行为；剔除突发态数据后的往返延迟序列趋向于呈现长程相关特性，Hurst指数在0．55～0．8之间。

| Abstract: | This paper analyzes scaling behavior of Internet round-trip time(RTT) based on small-interval(10ms) measurements and finds that RTT series consist of two completely different components: spiky component and normal component.By using DFA method,it is found that the original RTT series do not exhibit simplex scaling behavior,but when removing spiky component,RTT series show long-range dependence,with Hurst exponent ranging from 0.55 to 0.8. |
