This paper devoted to the development of software designed to simulate networks with heterogeneous load, with further determination of the characteristics of network traffic. Traffic pulsations, inhomogeneities of application flow form an uneven load in computer networks. The process of modeling networks before their direct design is of paramount importance, respectively, the development of software (tool) for modeling networks is an important task. The development of algorithmic and software tools for modeling network traffic greatly simplifies the process of researching computer networks and contributes to the development of recommendations for further redistribution of load between network nodes. Each model under development has its own limitations and the reliability of probabilistic simulation results, which depend on the chosen mathematical apparatus, depends on them. The apparatus of queuing theory allows analyzing the results obtained at the level of their average values, and simulation modeling allows monitoring changes in network traffic over the entire simulation period for a set model time. The developed software is based on the modification of the already existing classical algorithm for calculating the performance of computer networks with heterogeneous traffic. The algorithm allows to optimize the values of parameters aimed at improving the performance indicators of networks with heterogeneous load.

Keywords: modeling, computer networks, network traffic, networks with non-uniform load, performance.
