    Abstract: A network system includes a plurality of first computers, which transmit and receive data via a network and are equipped with a plurality of active and standby communication paths. A second computer is connected with the first computers via the network. Each first computer acquires path information concerning active and standby communication paths in the network and traffic of the active communication path and transmits them to the second computer. The second computer: predicts a load on each network node when the communication path is to be switched to each standby communication path; selects a first computer, whose communication path should be switched, and a standby communication path, which is a switching target, based on the prediction result; and requests the first computer to switch the communication path to the standby communication path.
