ABSTRACT:
A cluster computing system includes an active system and a standby system connected via wire networks. The active system and the standby system each has a wireless communications apparatus, such that when all of the wire networks connecting the active system with the standby system are disconnected, the wireless communications apparatus of the active system reports the standby system of the failure of the active system using its wireless communications capability with the wireless communications apparatus of the standby system. The report includes the verification ID of the active system, and the standby system begins operation upon receiving a packet containing the verification ID.
