The performance comparison between TCP Reno and TCP Vegas

Following the development of TCP Vegas, the performance comparison between TCP Reno and TCP Vegas has not been discussed thoroughly. The discussion of the revised TCP version, TCP Vegas, remains insufficient to decide whether or not to use it. This paper attempts to compare the performance, throughput and fairness, of Reno and Vegas in the network environments with homogeneous and heterogeneous versions of TCP. Results in this study indicate that while TCP Vegas obtains better throughput and fairness in homogeneous cases, if fails to outperform Reno in heterogeneous cases. This phenomenon prevents users from adopting TCP Vegas despite its better performance.
