现代网络流量的不断增加和数据交换形式不断变化,网络流量的研究难度也在不断增加,特别是对网络行为的研究更加重要。对尺度行为的研究方法进行了探讨,解释了多重分形的估计方法,并对尺度行为估计的算法进行复杂度分析和无偏性验证,对尺度行为的研究有着重要意义。 The increasing of modern network traffic and the form of data exchange are constantly changing, and the research of network traffic is also increasingly difficult, especially for the study of network behavior. The research methods of scale behavior are discussed, the multifractal estimation method is explained, and the complexity analysis and unbiased verification of scale behavior estimation algorithm are of great significance to the study of scale behavior.
