Traffic model and performance evaluation of Web servers

A new model of Web traffic and its application in the performance evaluation of Web servers is presented. A traffic model at the session level, formulated as a stochastic marked point process, which describes when users arrive and how they browse the server is also proposed. An analysis on the Apache server, the currently most used Web server software is studied. The impact of the traffic parameters on the HTTP request arrival process and the packet arrival process is also analyzed.
