Heartbeat detection device and method applied to distributed system and network equipment

Abstract

The invention discloses a heartbeat detection device and a heartbeat detection method applied to a distributed system and network equipment. According to the method, subequipment monitors whether an application module on the subequipment normally occupies the processing resource of a central processing unit (CPU) or not; if the application module is monitored to normally occupy the processing resource of the CPU completely and software heartbeat period cannot be timed, the subequipment transmits a software heartbeat message to primary equipment; and the software heartbeat message is still transmitted to the primary equipment under the conditions that the processing resource of the CPU is occupied normally and completely and the software heartbeat period cannot be timed, so that misjudgment on the subequipment by the primary equipment can be reduced, the accuracy and the reliability of heartbeat detection are improved, and the problems of misjudgment, low accuracy and low reliability of heartbeat detection in the prior art can be solved.

Description

technical field [0001] The present invention relates to network communication technology, in particular to a heartbeat detection device and method and network equipment applied to a distributed system. Background technique [0002] A distributed system is a multi-device architecture interconnected by a communication network, and each device performs tasks through coordination and interaction. A distributed system includes multiple devices, and the multiple devices include a master device, and other devices are sub-devices. [0003] The survival status of the sub-device is monitored through heartbeat detection between the main device and the sub-device. figure 1 A schematic diagram showing the principle of heartbeat detection, such as figure 1 As shown, the sub-device 2 starts a timer (Timer), and sends heartbeat information to the main device 1 when the timing period of the timer arrives. After the master device 1 receives the heartbeat message from the slave device 2, it...
