Stochastic Modeling of TCP/IP over Random Loss Channels

摘要

An analytical framework for modeling the performance of a single TCP session in the presence of random packet loss is presented that is based on a semi-Markov model for the window size evolution. The model predicts the throughput for LANs/WANs (low and high bandwidth-delay products) with good accuracy, as compared against simulation results with ns simulator. Generally, higher speed channels are found to be more vulnerable to random loss than slower channels, especially for moderate to high loss rates.
