Abstract

Les modes de réalisation de la présente invention concernent un système de stockage en nuage, un procédé et un système de stockage de données multimédias. Un procédé de stockage de données multimédias est mis en œuvre sur un dispositif d'acquisition d'image. Ledit procédé consiste : à demander un système de stockage en nuage pour une seconde adresse de réseau sur la base d'une première adresse de réseau pré-stockée ; la seconde adresse de réseau étant l'adresse de réseau d'un nœud de stockage cible, le nœud de stockage cible étant un nœud de stockage attribué par le système de stockage en nuage au dispositif d'acquisition d'image pour le stockage de données multimédias du dispositif d'acquisition d'image ; après l'obtention de la seconde adresse de réseau, à télécharger en amont, sur la base de la seconde adresse de réseau, des données multimédias cibles destinées à être stockées dans le système de stockage en nuage ; les données multimédias cibles étant stockées dans le nœud de stockage cible du système de stockage en nuage. Ainsi, selon cette solution, les données multimédias du dispositif d'acquisition d'image sont stockées directement, plutôt que transférées par un serveur de plateforme à un nœud de stockage dorsal, ce qui permet de réduire la consommation de ressources de bande passante de réseau et d'améliorer l'efficacité de téléchargement en amont de données multimédias.
