一种自适应的容灾系统心跳检测算法

随着信息系统在关键应用中的普及,信息系统的容灾能力日益成为人们关注的焦点,而心跳技术是构建容灾系统所必需的关键技术之一。本文研究了一种基于PULL模型的自适应心跳算法。该算法根据节点及网络状况输出一个量化结果,通过该结果与阈值的比较来判断系统的可用性,可用于容灾系统可用性的检测。

An Adaptive Heartbeat Inspection Algorithm for Disaster Recovery Systems

With the rapid development of information systems in critical applications, their disaster recovery capability becomes a focus, and heartbeat is one of the crucial techniques in building a disaster recovery system. This article studies an adaptive heartbeat algorithm based on the PULL mode, which uses the nodes and network~s status to output a quantitative value and performs comparisons between the quantitative output and the threshold value to decid e a disaster recovery system＇s serviceability, which can be used for detecting the system＇s dependability in the disaster recovery environment.
