分析在15个大区域交通轨迹期间发生的300万个TCP连接。这些踪迹聚集在五个“存根”网络和两个Internetwork网关上，从而提供了广泛的交通。作者得出了描述与Telnet，NNTP，SMTP和FTP连接相关的随机变量的分析模型。为了评估这些模型，作者提出了一种定量方法，将其有效性与TCPLIB等经验模型的有效性进行了比较[Danzig和Jamin，1991]。该方法还允许确定哪些随机变量随着时间的推移或存根网络和Internet Workwork网关之间的明显变化。总体而言，作者发现分析模型提供了良好的描述，并且通常对各种分布以及经验模型进行建模。 >
Analyzes 3 million TCP connections that occurred during 15 wide-area traffic traces. The traces were gathered at five "stub" networks and two internetwork gateways, providing a diverse look at wide-area traffic. The author derives analytic models describing the random variables associated with TELNET, NNTP, SMTP, and FTP connections. To assess these models the author presents a quantitative methodology for comparing their effectiveness with that of empirical models such as Tcplib [Danzig and Jamin, 1991]. The methodology also allows to determine which random variables show significant variation from site to site, over time, or between stub networks and internetwork gateways. Overall the author finds that the analytic models provide good descriptions, and generally model the various distributions as well as empirical models. >
