Abstract
The communications statuses of a plurality of clients are checked in a fixed cycle; when a check result corresponding to at least one of the clients is irregular, the estimated number of clients which will be able to receive communications services from an alternative server (standby server) after the server is switched from a main server (present server) to the alternative server is calculated based on all said check results; the calculated number of clients is compared with the number of clients which are receiving the communications services from the main server prior to the switch, and the appropriateness of the switch is determined based on the result of this comparison; the switch from the main server to the alternative server is controlled based on the result of the determination.
