Abstract
A method of controlling congestion in a communications network comprising a plurality of terminals, comprises the steps of: receiving a message or a message fragment at a given instant; evaluating the number of terminals currently sending; defining a congestion window, of duration ΔTf configured so as to be proportional to the number N of terminals currently sending and inversely proportional to the maximum input loading G of the network which makes it possible to obtain a substantially zero rate of retransmissions; for each terminal and each message or message fragment to be sent, make the start of the congestion window coincide with the given instant of receipt of a message or message fragment and define an actual instant of sending of the message or message fragment as a random value taken in the congestion window.
