The purpose of the investigation presented in the paper is the obtaining and analysis of statistic de-pendences of service quality characteristics for the traffic of HTTP and FTP applications. By means of Riverbed software product there is created a simulation model with the aid of which the essential characteristics (time necessary for the extraction of the whole of a page and probability of packages loss) are obtained. On the basis of the dependences presented as diagrams there is carried out the analysis of data obtained as a result of which the following conclusion is drawn: on the whole the dependencies of service quality charac-teristics for traffics of HTTP and FTP applications do not differ considerably and have the same trends owing to the application of an identical report of a transport level.
