Executive Summary

TCP shows poor performance in high speed networks with large latencies as well as in wireless networks where link error rates are high. The main two factors degrading TCP performance are related to its conservative policies for sending rate increase and treating all packet losses as congestion-related. In order to address these limitations a number of solutions have been proposed. Most of them either adapt to the large bandwidth-delay product when the loss rate is low (below 10-7) or face the problem of high error rate (above 10-3) not accounting for high-speed connections. In this paper, the authors propose a novel approach Kikolo TCP. It is based on Markov Modulated Poisson Process (MMPP) to control the congestion window evolution.
