Congestion control, Vegas, fairness, asymmetric network.
TCP Vegas proposed a mechanism to improve TCP
congestion control in the Internet. However, Vegas
exhibits unfairness characteristics towards multiple TCP
connections and does not perform well in a traffic
asymmetric network. This paper introduces a simple
modification to TCP Vegas, namely STT-Vegas, to
improve the performance of TCP Vegas and present its
performance for multiple TCP connections. The
simulation studies have shown that STT-Vegas provides
better overall performance than its counterparts (i.e.
Vegas, Reno) on fairness, throughput and packet loss in
various network traffic scenarios.
