摘要：
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.
