....values. With the help of a WAN emulator simulating a satellite link, Zhang et al. 26] study the performance of various TCP versions over long delay links. TCP Vegas achieves only half the throughput of TCP Tahoe or TCP Reno. However, it retransmits much less than other TCP variants. Ahn et al. [2] introduce a new technique to speedup simulation of high speed, wide area packet networks. The evaluation section presents the results of running a stripped down version of TCP Vegas, which includes only its congestion detection and window adjustment scheme, over a gigabit network. In the ....

....considering a version of TCP Vegas which merely includes the novel congestion avoidance mechanisms (Vegas only ca) we see only a minor improvement over TCP Reno for low background traffic loads and even lower throughputs in situations with high background load. Thus, our data backs other research [2] [5] claiming that using only TCP Vegas s congestion avoidance mechanism may result in lower throughput compared to TCP Reno. 8 Recall, that TCP Vegas refers to the corrected version described in Section VI. TABLE VII AVERAGE THROUGHPUT [KB S] PER CONNECTION. Background traffic low high Reno ....
