Adaptive heartbeat keep-alive method and device, client and storage medium

Abstract

The application discloses a self-adaptive heartbeat keep-alive method and device, a client and a computer readable storage medium. The method comprises the following steps: when the keep-alive state of a northbound interface is initialized as a high-frequency detection state, periodically sending a registration packet to a controller at a first preset frequency; when a registration feedback packet from the controller is received, switching the keep-alive state from the high-frequency detection state to a low-frequency stable state, and adjusting the sending frequency of the registration packet to a second preset frequency, wherein the first preset frequency is higher than the second preset frequency; in the low-frequency stable state, starting a timeout timer, and if the registration feedback packet is not received after the timer expires, switching the keep-alive state back to the high-frequency detection state. By dynamically adjusting the heartbeat frequency, the application can ensure high reliability and fast response of the connection, and significantly reduce the bandwidth resource occupation of the control packet.
