<p>The system and method apply to the flow of packets carried by asynchronous time-division multiplexes (EPACi). The packets of a communication are identified through their label and the identity of the multiplex conveying them.
<??>The method consists in allotting a predetermined clock frequency and a predetermined threshold value to each communication, in measuring the difference between the number of incoming packets belonging to the communication and the number of pulses delivered by the clock, in bounding this difference below, and if the difference reaches the predetermined threshold, in triggering a signalling (DEP) which causes packets belonging to the relevant communication to be eliminated for as long as the difference does not again become less than the predetermined threshold. The signalling (DEP) is exploited by the control units for the switch (XPAC) which transmit a message to the source of the relevant communication requesting it to reduce its throughput, when this is possible, and, in any event, a message advising it of a loss of packets.
<??>Systems implementing this method are described.
