Patrick Loiseau, Paulo Gonçalves, Julien Barral, Pascale Vicat-Blanc Primet
2010 Performance evaluation (Print)  
In this paper, we propose a method to describe the deviations of a long TCP flow's throughput from its almost-sure mean value.  ...  Applying this result to a Markov chain modeling the congestion window's evolution of a long-lived TCP flow, we show that it is practically possible to quantify and to statistically bound the throughput's  ...  This method relies on a recent ergodic large-deviations result that we theoretically derived in [6] , and that we applied here to a simple Markov-chain model of the evolution of TCP Reno's congestion  ...
