Abstract

L'invention concerne un stockage rattaché à un réseau (NAS). Un commutateur de mode permet d'établir une connexion directe entre une unité de stockage dans le NAS et un terminal d'utilisateur, ainsi qu'une fonction de base du NAS afin d'effectuer une communication de données avec un terminal d'utilisateur en réseau. Il est ainsi possible de minimiser les gênes pour l'utilisateur qui résultent des limitations d'une ligne de réseau. Le NAS peut également être relié à des données dans un stockage Internet externe, ce qui améliore l'utilisation et les caractéristiques d'utilisation.
