[0031] The application will be further described in detail below in conjunction with the drawings.
[0032] figure 1 A schematic flowchart of a lease-based heartbeat protocol method according to an aspect of the present application is shown. The method includes step S11 and step S12.
[0033] Wherein, the step S11 includes: sending a heartbeat request to the service device during the lease period, and receiving a heartbeat request response from the service device; the step S12 includes: when the heartbeat request response is abnormal, determining based on a reverse index backoff algorithm Retry sending interval time, and sending a retry heartbeat request to the service device again after the retry sending interval time until the lease expires or the corresponding heartbeat request response is normal.
[0034] It should be noted that in the embodiments of this application, the heartbeat between the client device and the service device is a periodic process. Under normal circumstances...
