Abstract

An analytical model of the Transmission Control Protocol (TCP) New Reno [7] performance through a Continuous-Time Markov Chain (CTMC) is presented and its theoretical predictions are corroborated by the well known network simulator ns-2 [15]. An existing TCP Reno model [6] is modified in order to characterise the NewReno algorithm. The NewReno version is modelled given its proven better performance over channels presenting high loss rates and its extensive deployment in current web servers [14].
