提出了一种通过研究网络运行关键指标的数据分布特性的方式,以实现对网络运行指标的异动情况进行主动发现并及早捕捉网络性能隐患的预警方法。采用正态分布中的“3σ”规则以实现对关键指标监管门限的自动设定,做到对网络隐性故障、无线性能指标异常等事件做出及时预警,以便运维人员及时发现并解决网络隐患,确保网络平稳运行。
This paper presents a way to find out the data distribution characteristics of key indicators in network operation so as to realize the early detection of the abnormal behavior of network operation indicators and the early detection of network performance problems. The “3σ” rule in the normal distribution is used to automatically set the regulatory threshold of the key indicators so as to make early warning to the hidden troubles of the network and the abnormality of the wireless performance indicators in time so that the operation and maintenance personnel can promptly discover and Solve network problems, to ensure smooth operation of the network.
