Improvement on Real-Time Capability of Heartbeat Mechanism
Zhan Jie Wang, Wen Chen, Hai Long Wang · Advanced materials research · 2010
Heartbeat mechanism is the key technology of fault detection in cluster system, and the performance of heartbeat detection restricts the efficiency of high-availability clusters. Heartbeat packets will be delayed or even lost in the case of system or network overload, leading to the lack of real-time detection, the increased misjudgment rate, and reducing the reliability of the system. Aiming at the issue, this paper presented a new real-time heartbeat mechanism. By controlling the time of sending heartbeat packets, real-time Ethernet TTEP avoids the network delay and collision, which will speed up the detection of node failure, thereby increase the availability and stability of cluster system.
