交通数据的去趋势波动分析

Detrended fluctuation analysis of traffic data

Xiaoyan Zhu, Zonghua Liu, Ming Tang

摘要:

不同的路由策略会导致不同的网络流量行为。本文采用去趋势波动分析(DFA)方法对三种典型路由策略下的流量数据进行相关性分析,发现流量数据的相关程度可以分为三个区域,即:弱、中、强相关性。DFA标度在弱相关和强相关区域都是常数,但在中等相关区域单调增加。我们建议将复杂网络上的业务分为三个阶段,即,空闲、缓冲和拥塞阶段,而不是之前认为的两个阶段,即,自由和拥挤阶段。

英文摘要:

Different routing strategies may result in different behaviors of traffic on internet. We analyze the correlation of traffic data for three typical routing strategies by the detrended fluctuation analysis (DFA) and find that the degree of correlation of the data can be divided into three regions, i.e., weak, medium, and strong correlation. The DFA scalings are constants in both the regions of weak and strong correlation but monotonously increase in the region of medium correlation. We suggest that it is better to consider the traffic on complex network as three phases, i.e., the free, buffer, and congestion phase, than just as two phases believed before, i.e., the free and congestion phase.
