Disclosed is a network system comprising: a plurality of routers 704 and 705 connected to each other through a network; pseudo redundant configuration setting means 702 and 703 which are connected respectively to the routers and which perform a communication using a redundancy protocol with respective routers; and association control means 701 connected to the pseudo redundant configuration setting means 702 and 703, wherein when a server 716 is a backup server and its backup state needs to be maintained, the pseudo redundant configuration setting means 703 issues a signal for maintaining a standby state to the router 705, and when servers are switched between a standby state and operating state, the association control means 701 transmits a switching instruction for switching between a standby state and operating state to the pseudo redundant configuration setting means 702 and 703.
L'invention concerne un système de réseau comprenant des routeurs (704 et 705) raccordés par un réseau, des moyens de configuration pseudo-redondants (702 et 703) raccordés aux routeurs individuels pour des communications par protocole redondant, et un moyen de commande d'inter-verrouillage (701) raccordé aux moyens de configuration pseudo-redondants (702 et 703). Lorsqu'un serveur (716) est un serveur de sauvegarde et qu'il conserve un état de veille, le moyen de configuration pseudo-redondant (703) émet vers le routeur (705) un signal pour demeurer en l'état de veille. Lorsque le serveur est commuté de l'état de veille vers un état actif, le moyen de commande d'inter-verrouillage (701) envoie aux moyens de configuration pseudo-redondants (702 et 703) une instruction pour commuter l'état de veille et l'état actif.
