ABSTRACT
In this paper we analyze the performance of a TCP­like AEow
control in a lossy environment. The transmission rate in the
control scheme that we consider has a linear growth rate;
whenever a loss occurs, the transmission rate is halved. This
approximates the performance of several versions of TCP
that divide their congestion window by two when a loss is
detected. We propose a mathematical model that allows to
account for burstiness in the loss process. We compute the
expected transmission rate and its moments at some poten­
tial loss instants, and provide a useful implicit expression for
the Laplace Stieltjis Transform. This allows us to compute
explicitly the time average of the transmission rate as well
as its moments. We show that the time average of the trans­
mission rate is indeed sensitive to the distribution of losses,
and not just to the average loss rate: for a given average loss
