Abstract

L'invention concerne un moteur de service de débit binaire disponible (ABR) utilisé dans un système de commutation par paquets. Une unité de traitement de cellules avant génère un premier signal de départ et extrait un débit de cellule courant (CCR) et de débit de cellule minimum (MCR) d'une cellule de gestion de ressources (RM) avant, lorsqu'elle reçoit la cellule RM avant. Une unité d'estimation du nombre (|Q|) de circuits virtuels étranglés localement détermine si (CCR-MCR) est inférieur au débit binaire explicite (ER) lorsqu'elle reçoit le premier signal de départ, considère que la cellule RM reçue contribue à (|Q|) si (CCR-MCR) est inférieur à ER, accumule le degré de contribution et calcule |Q|. Un moteur ER calcule ER lorsqu'il reçoit un troisième signal de départ. Une unité de traitement de cellules arrière détermine si le ER calculé par le moteur ER est inférieur à la somme de ER et de MCR extraits d'une cellule RM arrière lorsqu'elle reçoit la cellule RM arrière et écrit le ER calculé dans la cellule RM arrière si le ER calculé est inférieur à la somme de ER et de MCR. Une horloge envoie le deuxième signal de départ à l'unité d'estimation de |Q| à chaque première période et le troisième signal de départ au moteur ER à chaque deuxième période.
