紧耦合分布式系统中的故障过滤算法

Algorithm of fault filter in tight coupling distributed system

分布式系统中的各部分在运行过程中,由于外界或自身因素的影响,会产生瞬态故障、间歇故障或永久故障,要处理故障,首先必须识别出严重故障。增量/减量过滤算法根据故障性质、出现频率和严重程度,设置增量、减量和门限值,实现灵活的故障过滤策略,保证系统可靠、稳定地运行。

The transient, intermittent and permanent faults may happen because of the influence of the external condition or the internal devices when the components work in the distributed system. In order to process the fault, the importance is to identify the serious fault. According to the fault feature, frequency and the degree of seriousness, set the gain, the drain and the threshold in the filter algorithm of gain/drain. It filtered the fault flexibly and ensured the system to work reliably and stably.
