Improving the performance of TCP Vegas in a heterogeneous environment

Many results indicate that TCP Vegas exhibits better throughput and higher stability than TCP Reno in homogeneous cases where a single version exists, but it performs poorly in heterogeneous cases where two versions coexist. Hence users are delaying, even protesting, the adoption of TCP Vegas. The difference in performance is due to the fact that Reno vibrates in the high throughput level and Vegas almost stabilizes in the low level. We propose two simple approaches to address this problem, the RED (random early discard) approach and parameter adjustments to Vegas. These approaches enable Vegas to achieve its fair share of bandwidth, even gaining an advantage over Reno, encouraging users to switch their TCP from Reno to Vegas
