   Abstract: In this special study two analytical models for TCP’s throughput are compared with simulated results. Based on the study, an ns2 simulation exercise is developed for the course “Simulation of telecommunications networks”. The goal of the exercise is to make the students familiar with ns2 simulator as well as TCP’s congestion control and performance. Furthermore, the purpose is to give an idea of how analytical models can be verified with simulations. The structure of the study is following: In the first part, instructions for the simulation exercise are given. The instructions consist of theory explaining TCP’s congestion control algorithms and the analytical models for TCP’s throughput and description of the main features of ns2 simulator and Otcl language. Finally, in the second part of the study, simulation results from different scenarios are presented and analysed.
