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 ...
