Abstract

L'invention concerne un procédé, un appareil, et un système de gestion d'une ressource virtuelle. Le système comprend un dispositif de gestion de ressource, et un dispositif de configuration de ressource. Le dispositif de configuration de ressource est configuré pour générer un identificateur de déploiement d'une ressource virtuelle, et inclure l'identificateur de déploiement dans une demande de ressource virtuelle devant être envoyée au dispositif de gestion de ressource, l'identificateur de déploiement étant utilisé pour représenter des informations de localisation de la ressource virtuelle. Le dispositif de gestion de ressource est configuré pour recevoir la demande de ressource virtuelle envoyée par le dispositif de configuration de ressource, et gérer des éléments de réseau correspondant à la ressource virtuelle d'après l'identificateur de déploiement de la ressource virtuelle. De cette manière, le dispositif de gestion de ressource peut agréger des éléments de réseau ayant le même identificateur de déploiement de sorte à définir la latitude d'un plan de gestion à des fins de gestion et de maintenance, les éléments de réseau ayant le même identificateur de déploiement formant une vue de maintenance de site.
