Abstract

Un commutateur de réseau ATM (100) comprend une pluralité de contrôleurs de fente (112a-h), dont chacun est couplé à un tissu de commutateur (114) et à une liaison externe (116a-h), ainsi qu'à un contrôleur de système (122) via un RLE (120). Chaque contrôleur de fente (112a-h) comporte un processeur programmé pour envoyer des messages Q.2931 au contrôleur de système (122) via le RLE (120) et pour recevoir des informations du contrôleur de système (122) via le réseau local (120). Le contrôleur de système (122) est programmé pour interpréter les messages Q.2931, mettre à jour les tables de routage des contrôleurs de fente (112a-h) via le RLE (120) et transmettre un paquet contenant les messages Q. 2931 à un contrôleur de fente (112a-h) approprié via le RLE (120). Ensuite, le contrôleur de fente (112a-h) rassemble les cellules ATM contenant les messages Q. 2931 pour les transmettre.
