Abstract: The TCP performance in the case of ATM asymmetric links is analgzed.Our goaal is to investigate the impact of asymmetry on TCP performace.By defining the asymmetry parameter and building the model, we deduce theformula to calculate the TCP perfomance.Effectiveness of the deduction is verified by simulation studies.We conclude that asymmetry has a direct impact on TCP performance and the mean throughput is linear to the asymmetry parameter under the same condition.

Key words: ATM, asymmetric digital subscriber link, TCP
