METHOD OF IMPROVING THE PERFORMANCES OF A TRANSMISSION PROTOCOL USING A RETRANSMISSION TIMER

摘要

The invention relates to a method of improving the performances of a transmission protocol using a retransmission timer. The time-out (RTO) of said retransmission timer is adjusted according to statistics over the round-trip time (RTT), said statistics including a dispersion estimate. The inventive method is essentially characterised in that a jitter is introduced into said round-trip time (RTT). In this way, the dispersion is controlled so that a minimum value therefor is ensured, thereby reducing the probability of spurious timeouts in relation to said retransmission timer.
