Abstract | We analyze 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. We derive analytic models describing the random variables associated with TELNET, NNTP, SMTP, and FTP connections. To assess these models we present a quantitative methodology for comparing their effectiveness with that of empirical models such as Tcplib [Danzig91]. Our methodology also allows us to determine which random variables show significant variation from site to site, over time, or between stub networks and internetwork gateways. Overall we find that the analytic models provide good descriptions, and generally model the various distributions as well as empirical models. |
