Abstract

TCP Vegas is a proactive congestion control mechanism proposed to improve TCP performance by using Round Trip Time (RTT) as a main parameter to monitor traffic condition and avoid congestion. However, TCP Vegas does not perform well on bidirectional links with unbalanced traffic, and on wireless links. A simple Single-Trip Time (STT) based modification to TCP Vegas, namely STT-Vegas, was introduced in [1] to improve the performance of TCP Vegas. It has been demonstrated that STT-Vegas outperforms Vegas in various network scenarios in wireline networks. This paper examines the performance of STT-Vegas in heterogeneous wired and wireless networks and investigates its possible enhancements in such networks.
