基于控制图法的网络告警突变预警机制

Early-warning schemes for alarm mutation in networks based on control chart

各种网元及其触发的告警量随着网络规模的扩大而大量涌现。传统的网络运行维护,即被动地对发生后的网络故障逐一进行派单处理,已经不能适应现如今复杂的网络管理。从影响客户感知、客户投诉、网络运行安全等维度,梳理出影响业务的各类网络重要告警标题,运用控制图方法,统计分析各类重要告警异常突变量的上下波动受控情况,结合业务影响关联分析,建立重要告警异常突变预警的预警模型和算法,提出了一种先于故障处理、主动挖掘隐患的网络告警预警动态闭环管控机制。

The amount of various network elements and alarms trigged is pretty startling with the expansion of the network. The traditional network operation and maintenance, that is, passively processed worksheet after the occurrence of network failure one by one, has been unable to adapt to the complex network management today. The various types of important service-related network alarm titles were sorted out, and the fluctuation under control for kinds of important alarms by control chart, establishes the graded early-warning model and algorithm for alarm mutation in networks combining with the service-related analysis, were analyzed. At last, a dynamic closed-loop control mechanism, which was preceded by fault occurred and actively digs into hidden troubles, was proposed.
