| 摘 要： | 针对大型网络流量测量中测量数据量巨大、不能有效地描述流量特征的问题，本文将近年来网络研究的热点自相似性运用在流量测量中。根据流量变化对自相似参数H的影响，提出了一种基于网络的自相似特性的流量测量采样方法。该方法降低了流量测量的采样频率，能够及时、准确地发现网络异常，并能使测量数据更准确地刻画流量特征。

| Abstract: | This paper introduce a traffic measurement method for the large network. According to the change in Hurst parameter caused by the network traffic,a traffic measurement sampling method is proposed based on the self-similarity.This method can reduce the sampling frequency and characterize the network traffic accurately. |
