Modelling performance of HTTP/1.1

Some theoretical aspects of data traffic using HTTP (hypertext transfer protocol) are investigated. The purpose of our modelling is to give an analytical method to evaluate the expected performance of data transfer under various circumstances. HTTP/1.1, with and without pipelining and TCP, is in the focus of our study. The performance is mainly investigated from the client´s point of view, and the main metric of interest is the average throughput that a given user experiences. The results of the computations can be used for predicting the offered load of the network and the quality of service of Web-browsing, in both wired and wireless environments.
