Study of alarm pretreatment based on double constraint sliding time window
基于双约束滑动时间窗口的告警预处理方法研究

In communication alarm correlation analysis, traditional time window has low efficiency on extracting data. This paper first proposed a novel double constraint based sliding window method. With double constraint condition, the window width and sliding step of the time window could automatically adjust according to the actual situation of alarm sequences, and the mid-point of the time period was selected as a reference point. The performance testing of the algorithm indicates that this method has higher extract efficiency than traditional methods, which is suitable for alarm data in telecommunication networks.
