Abstract
A system and method for regulating real-time the heartbeat frequency of the host according to the user-requested frequency, wherein the heartbeat frequency of the host is regulated through the service request signal sent from the user's end to the host by making use of a cluster system comprising a host and a backup host. Firstly, a frequency correspondence table is established. The host and the backup host transmit signals to each other at a predetermined frequency, which is set to the most recent heartbeat frequency of the host. Then the transmitting times of a plurality of service request signals are recorded to calculate the frequency of the most recent service request signal. Finally, the most recent heartbeat frequency of the host and the frequency of the most recent service request signal are compared to determine if the heartbeat frequency of the host needs to be regulated.
