Abstract

Un réseau ATM est composé d'un ensemble de commutateurs interconnectés (110-118) et de passerelles (131, 133). Ce réseau ATM est capable de fournir à la fois un service avec connexion et un service sans connexion. Quand un service sans connexion est demandé au niveau de l'interface d'entrée, les adresses de source et de destination sont insérées dans l'en-tête et des champs contenus dans l'en-tête sont réglés à des valeurs indiquant qu'un service sans connexion est demandé et si un traitement supplémentaire est demandé ou non. Au niveau de chaque noeud entre l'interface d'entrée et l'interface de sortie, ou un service sans connexion est demandé, chaque cellule ATM est acheminée en fonction soit de son adresse de source et de son adresse de destination, soit d'une table d'acheminement établie par un protocole d'acheminement ou par une gestion de réseau.
