Abstract

We analyze the characteristics of Internet traffic by considering its correlation properties. First, a simple measurement is performed, by using the autocorrelation technique, to illustrate the correlation properties of the HTTP/Web and the e-mail (SMTP) services. The ACF (autocorrelation factor) and PACF (partial ACF) measurements are applied to examine the correlation characteristics of the traffic correlation within consecutive hours. The measurement results indicate that correlation with one-hour lag is acceptable for both services. Then the autocorrelation of each service is performed, respectively, to understand the correlation property of these two services. The experiment results illustrate that the HTTP/Web service has much higher self-correlation, especially for one hour lag, than the e-mail service. Finally, a heuristic bandwidth allocation method is proposed by considering the correlation characteristics. The proposed method is suitable for the management of Internet bandwidth dynamically.

互联网流量建模与带宽分配的实验研究

我们通过考虑互联网流量的相关特性来分析互联网流量的特征。首先，通过使用自相关技术执行一个简单的度量，以说明HTTP/Web和电子邮件(SMTP)服务的相关属性。采用自相关因子(ACF)和部分ACF (PACF)测量来研究连续小时内流量相关性的相关特征。测量结果表明，一小时滞后的相关性对两种服务都是可以接受的。然后分别执行每个服务的自相关性，以了解这两个服务的相关性属性。实验结果表明，与电子邮件服务相比，HTTP/Web服务具有更高的自相关性，特别是在延迟1小时的情况下。最后，提出了一种考虑相关特性的启发式带宽分配方法。该方法适用于网络带宽的动态管理。
