Abstract

La présente invention porte sur un procédé fondé sur un modèle de battement de cœur pour détecter un état de communication d'un grand appareil redresseur. Un modèle de battement de cœur pour améliorer un mécanisme de battement de cœur est produit par conception d'un état de nœud de réseau, amélioration du mécanisme de battement de cœur et définition d'un protocole de paquets de données de battement de cœur. Un paquet de battement de cœur est transmis entre une extrémité de surveillance à distance située sur une couche d'application de réseau et une extrémité surveillée située sur une couche de surveillance sur site par utilisation du modèle de battement de cœur, de manière à déterminer l'état d'une connexion de communication entre l'extrémité surveillée et l'extrémité de surveillance à distance; et en outre, une mesure correspondante est prise pour améliorer la disponibilité et la fiabilité d'un service de nœud de réseau et d'une communication; de plus, la charge réseau d'un unique serveur de surveillance à distance, et la charge réseau d'un serveur pour lequel de multiples extrémités surveillées sont dans un mode de fonctionnement, sont efficacement réduites.
