— In recent years, several new TCP congestion control algorithms have been proposed to improve TCP performance over very fast, long-distance networks. High bandwidth delay products require more aggressive window adaptation rules, yet maintaining the ability of controlling router buffer congestion. We define a relatively simple experimental scenario to compare most current high speed TCP proposals under many metrics: efficiency, internal fairness, friendliness to Reno, induced network stress, robustness to random losses. Based on the gained insight, we define Yet Another High-speed TCP, as a heuristic attempt to strike a balance among different opposite requirements.
