Enhanced bandwidth estimation algorithms in the TCP congestion control scheme

Abstract

The use of enhanced bandwidth estimation procedures within the congestion control scheme of TCP has been recently proposed as a way to improve the performance over links affected by random losses. In this paper we propose TIBET (Time Intervals based Bandwidth Estimation Technique), a new bandwidth estimation scheme that can be implemented within the TCP congestion control procedure by modifying only the sender-side of a connection. TIBET allows TCP sources to achieve higher performance over wireless links, while guaranteeing a good fairness level with TCP Reno over wired networks. We analyze and compare the performance of the new algorithm with that of previously proposed schemes. © 2003 by Springer Science+Business Media New York.
