This abstract describes a simple and accurate analytic model for the steady state throughput of TCP Vegas, as a function of round trip time and packet loss rate. Such models have previously been developed for TCP Reno. However, several aspects of TCP Vegas need to be treated quite differently from their counterparts in Reno. In particular, TCP Vegas employs an algorithm to detect the incipient stages of congestion in the network and preemptively adjusts the sending rate to avoid losses. The proposed model reflects this behavior, as well as Vegas' new slow start mechanism, and the most important of the innovative congestion recovery mechanisms introduced in TCP Vegas. Initial validations against the ns-2 simulator configured to simulate TCP Vegas are presented.
