TCP性能分析。两个分析模型：拥塞控制，各种场景；给出仿真练习；-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 descr iption 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.
