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.

提供了一种基于租约的心跳协议方法。 该方法可以包括在租期内向服务器设备发送心跳请求，并且从服务器设备接收心跳请求响应; 并根据所述心跳请求响应异常确定自适应间隔重试发送，并在所述重试发送间隔过去后，再次向所述服务器发送重试心跳请求，直至所述租期到期或对应的心跳请求响应正常 。 如此，可以在心跳请求重试的初始阶段以相对大的时间间隔发送两个连续的重试心跳请求。 在心跳请求重试的稍后阶段，与重试心跳请求相关联的时间间隔减少，从而可以以更高的速度发送重新发送的心跳请求。
