Abstract

Un serveur en nuage (2) comprend : une unité de stockage d'informations d'équipement (231) qui stocke des informations de table d'équipement dans lesquelles des informations d'adresse MAC pour un équipement sous commande sont associées à des informations d'adresse MAC pour un dispositif de commande (1) ; une unité de commande d'équipement (217) qui génère des informations de commande comprenant des informations de paramètre de commande, les informations d'adresse MAC pour l'équipement sous commande, et les informations d'adresse MAC pour le dispositif de commande (1) correspondant aux informations d'adresse MAC pour l'équipement en cours de commande ; une unité d'encapsulation (218) qui génère des informations de notification de commande par encapsulation des informations de commande et ajout d'informations d'en-tête pour désigner le dispositif de commande (1) en tant que destination de transmission ; et une unité de transmission d'informations de notification (219) qui transmet les informations de notification de commande au dispositif de commande (1) sur la base des informations d'en-tête. Lors de l'acquisition des informations de notification de commande provenant du serveur (2), le dispositif de commande (1) élimine les informations d'en-tête des informations de notification de commande, désencapsule le résultat pour extraire les informations de commande, et transmet les informations de commande extraites à l'équipement sous commande.
