摘要: We study the unfairness problem for TCP Vegas. There are three sources to cause Vegas: α < β, over-estimation of base RTT, and multiple congested gateways. To solve caused by gateways, we propose a new version Vegas–Adaptive Vegas(A-Vegas) which assigns value parameters adaptively according number Simulation shows that A-Vegas not only can it also reduces over-estimation. introduce fairness index, RNBS (normal bandwidth sharing ratio), indicates ratio amount grabbed connection uniformly distributed bandwidth.
