Heartbeat detection method and heartbeat detection apparatus

Abstract

The invention discloses a heartbeat testing method, applied in a network device with service net mouth, comprising that: the network device periodically transmits heartbeat information to a testing opposite terminal through a heartbeat testing port, receives heartbeat response returned by the testing opposite terminal, selects a service net mouth free of service, when the heartbeat testing terminal does not receive the heartbeat response of the testing opposite terminal, transmits the heartbeat information to the testing opposite terminal through selected service net mouth; it is judged that, whether the selected service net mouth receives the heartbeat response of the testing opposite terminal, if true, determining the test opposite terminal is normal; otherwise, determining the testing opposite terminal. The invention also discloses a heartbeat testing device. According to the invention, judging correct degree of the tested state is advanced.

Description

Technical field [0001] The present invention relates to signal detection technology, in particular to a heartbeat detection method and heartbeat detection equipment. Background technique [0002] At present, in order to ensure business continuity, backup equipment is usually configured for key equipment processing services, and this key equipment is called the main equipment. The standby device detects whether the active device is faulty by sending a heartbeat message to the active device and receiving the heartbeat response returned by the active device, and takes over the business of the active device when the active device fails, thereby ensuring business continuity . [0003] The design ideas of main and backup equipment are widely used in many network systems. Take the network storage storage system as an example, figure 1 It is a schematic diagram of the networking structure of a network storage system in the prior art. Such as figure 1 As shown, the network storage syste...

Problems solved by technology

[0005] However, in practice, there may be such a situation that the peer-end processing function is normal, but the transmission link between the local-end heartbeat network port and the peer-end heartbeat network port fails, or the local-end and / or peer-end If the heartbeat network port fails, or the peer end is busy with business and has no time to process the heartbeat message, the local end will not receive the heartbeat response, so it will wrongly determine that the peer end is abnormal and restart the peer end.

Restarting the operation of the peer end will cause the business interruption of the peer end

[0006] It can be seen that the existing heartbeat detection scheme cannot accurately judge the status of the peer end. When the judgment is wrong, the peer end will be restarted under non-abnormal conditions, resulting in service interruption of the peer end under non-abnormal conditions.
