TCP Reno TCP Vegas

TCP Vegas version is expected to achieve higher throughput than TCP Tahoe and Reno versions, which are currently used in the Internet. However, we need to consider a migration path of TCP Vegas when it is deployed in the Internet. In this paper, we focus on the situation where multiple TCP Reno and Vegas connections coexist at the bottleneck router, by which the fairness property is investigated to seek the possibility of future deployment of TCP Vegas. We consider FIFO (First In First Out) and RED (Random Early Detection) as buffering discipline at the router, and evaluate the effect of RED algorithm on fairness enhancement.
