Abstract

L'invention concerne un procédé et un système de mesure de variation de retard unidirectionnelle dans un réseau, permettant de transmettre des paquets d'essai avec un indicateur de temps de transmission et un numéro de séquence. Le réseau reçoit un premier paquet d'essai et un second paquet d'essai et note leurs heures d'arrivée. Si les paquets d'essai sont séquentiels, la variation du retard unidirectionnelle est calculée entre les deux paquets d'essai. La variation du retard est égale à la différence entre le temps d'arrivée des deux paquets d'essai à laquelle on soustrait la différence entre le temps de transmission du premier et du deuxième paquet d'essai.
