Understanding highspeed TCP: A control-theoretic perspective.
Balázs Sonkoly, Tuan Anh Trinh, Sándor Molnár · 2005
One of the most promising solution for transport protocol over very high bandwidth-delay product networks is High-Speed TCP. However, little is known about its performance as well as its interaction with other elements of the network (such as the RED queue management). In this paper, a comprehensive control-theoretic analysis of HighSpeed TCP is provided. We develop a fluid-flow model of the HighSpeed TCP/RED network and use it to study its performance. The main contributions of this paper are the following. Firstly, we provide a fluid-flow model for High-Speed TCP/RED networks. Secondly, a comprehensive and systematic implementation methodology is described in detail. We also provide a Simulink-based framework for analyzing fluid-based models. Thirdly, we give stability conditions for HighSpeed TCP/RED networks. Finally, the results are validated by simulations using Ns-2 [11].
