Abstract

L'invention concerne des procédés et un appareil utilisant un commutateur, pour l'ordonnancement de la transmission de cellules sur une liaison de réseau. Le commutateur comprend une pluralité de files d'attente associées à chaque liaison. Des listes de files d'attente sont conservées pour chaque liaison. Dans une forme d'exécution, chaque liaison est associée avec plus d'un type de liste (le type de liste correspond à une catégorie d'ordonnancement) (61) et avec au moins une liste de priorité pour chaque type (la priorité de la liste correspond à une qualité de service). Il est possible d'accéder aux listes d'ordonnancement (61) pour effectuer une transmission de cellules depuis une file d'attente (35, 28) qui s'y trouve, suivant une séquence prédéterminée. Cette séquence dépend de la catégorie d'ordonnancement, de la priorité dans la catégorie d'ordonnancement considérée et du fait que les besoins en largeurs de bandes sont satisfaits ou non pour la catégorie d'ordonnancement particulière considérée. Ce système permet de garantir le respect des délais d'attente maximums pour chaque catégorie d'ordonnancement.
