Abstract

In this paper reservation algorithms for multi-service switching networks are proposed. Two new approximate methods of the point-to-point blocking probability calculation in the multi-service switching networks are also presented in the paper. These methods can be used for blocking calculation in the switching networks with and without reservation. Special attention is paid to the method for determining the effective availability, which directly affects the accuracy of the final results. The results of analytical calculations are compared with the data of digital simulation of switching networks without and with reservation.

Résumé

Cet article présente les algorithmes de réservation dans les réseaux de connexion à trafic intégré. On propose deux méthodes approchées du calcul de la probabilité du blocage point à point dans les réseaux de connexion multiservices. Ces méthodes proposées peuvent être appliquées au calcul du blocage dans les reseaux avec (et sans) mécanisme de réservation. En particulier, on fait attention à la manière de déterminer l’accessibilité effective de laquelle dépend l’exactitude du résultat final. Les résultats du calcul analytique de la probabilité du blocage sont comparés aux résultats de la simulation numérique des réseaux de connexion avec et sans réservation.
