Abstract

In this paper we describe and validate the analytic model of a mixed TCP Reno and TCP Vegas network scenario. There is experimental evidence that TCP Vegas overcomes the widespread TCP version, called TCP Reno, in a number of network environments. The incompatibility between TCP Vegas and TCP Reno in heterogeneous network scenarios has been also verified by means of several simulations. The model presented in this work allows to quantitatively evaluate this incompatibility, by computing the average throughput of a TCP Vegas source in presence of a concurrent TCP Reno source. This model can help us to better understand the reasons of the vulnerability of TCP Vegas in competing with TCP Reno sources.
