Abstract

La présente invention concerne, d'une part un dispositif permettant de configurer automatiquement plusieurs hôtes, et d'autre part un procédé à cet effet. Un commutateur de réseau fournit à un serveur de gestion de configurations de l'information d'adresses MAC correspondant aux hôtes connectés. Le serveur de gestion de configurations applique aux adresses MAC fournies les adresses IP spécifiées par un administrateur, puis transmet le résultat à un serveur DHCP. Le serveur DHCP affecte collectivement aux hôtes les adresses IP. Ensuite, un serveur TFTP télécharge dans les hôtes une image d'installation de système d'exploitation, puis installe le système d'exploitation. Enfin, un serveur HTTP transmet aux hôtes de l'information de définition d'environnement du système d'exploitation installé, et configure ainsi automatiquement les différents hôtes.
