TY - CPAPER AU - M.M. Nycz AU - Tadeusz Czachórski AB - This article presents the problem of modeling the basic elements of the transport system of the modern computer networks. The study of selected issues of the network topology uses a mathematical model of fluid flow approximations, which is based on mean value analysis. The model describes the effects of time varying packet traffic on the network switches and packet loss generation by the assumptions of active queue management mechanisms used in routers. The computations are due to our new software tool.
