Abstract

Un réseau de communication comprend une pluralité d'éléments commutateurs, un contrôleur pour les éléments commutateurs, et un gestionnaire de système. Le contrôleur comprend un système informatique principal et une système informatique de réserve, comportant un dispositif qui permet de commuter depuis le système informatique principal vers le système informatique principal de réserve en cas de défaillance du système informatique principal. Ce dernier communique des modifications d'état, sous forme de flot de messages, au système informatique de réserve, de façon à mettre celui-ci à jour en lui indiquant l'état actuel du réseau. Le système informatique principal lui fournit également des informations d'état à intervalles réguliers, qui lui permettent de détecter une défaillance dans le fonctionnement du système informatique principal.
