A new methodology for TCP evaluation in a multiuser web environment

This paper presents a new methodology to evaluate and graphically represent TCP performance in a web environment. The main novelty of this work is that it focuses on web environments involving a large number of connections, where the traffic model is extracted from real traces. In these cases, conventional tools are not efficient to handle the complexity of the analysis. The proposed framework includes: (i) a set of representative web browsing scenarios affected by different types of losses; (ii) a new analysis methodology to cope with the huge data volume related to the simulated connections and; (iii) a new graphical representation to allow an easy visualisation of the simulation results. To test the proposed methodology, an evaluation of the impact of two representative TCP configuration parameters for web traffic has been included.
