Abstract
A lease-based heartbeat protocol method is provided. The method may include sending a heartbeat request to a server device in a lease period, and receiving a heartbeat request response from the server device; and determining a retry sending at adaptive interval in response to the heartbeat request response being abnormal, and sending a retry heartbeat request to the server device again after the retry sending interval is past, until the lease period expires or a corresponding heartbeat request response is normal. As such, two successive retry heartbeat requests can be sent at a relatively large time interval at an initial stage of heartbeat request retry. At a later stage of the heartbeat request retry, the time interval associated with the retry heartbeat requests is reduced, such that re-sent heartbeat requests can be sent at a higher speed.
