自动交换光网络告警信息实时推送方法研究

Research on real-time push method of automatic exchange optical network alarm information

针对当前方法光网络告警信息实时推送准确性差的问题。提出基于模糊综合评判的光网络告警信息实时推送方法。利用小波变换监测自动交换光网络的故障,在小波变换中,光网络信号的奇异点是突变点,在自动交换光网络信号中,故障是由输出信号的变化来当作表面特征,通过对突变点的检测,完成光网络的故障监测。在此基础上,利用模糊判断矩阵对光网络中的异常行为分析,确定自动交换光网络中异常事件发生的间隔隶属度函数,并分析光网络中异常事件源IP地址的隶属函数,计算光网络中发生异常事件特征的相似度,得到自动交换光网络中异常事件的攻击过程,通过对告警阈值的计算,最终实现了自动交换光网络告警信息的实时推送。实验结果表明,提出方法在对告警信息实时推送时,推送用时较短,具有较高的工作效率,并且能够准确完成对光网络告警信息的实时推送。

For the current method,the optical network alarm information is pushed in real time with poor accuracy.A real-time push method for optical network alarm information based on fuzzy comprehensive evaluation is proposed.The wavelet transform is used to monitor the fault of the automatically switched optical network.In the wavelet transform,the singular point of the optical network signal is a sudden change point.In the automatic exchange optical network signal,the fault is caused by the change of the output signal as a surface feature.The detection of the point completes the fault monitoring of the optical network.On this basis,the fuzzy judgment matrix is used to analyze the abnormal behavior in the optical network,determine the interval membership function of the abnormal event in the automatic switched optical network,and analyze the membership function of the abnormal event source IP address in the optical network to calculate the optical network.The similarity of the characteristics of the abnormal events occurs,and the attack process of the abnormal events in the automatically switched optical network is obtained.By calculating the alarm threshold,the real-time push of the automatic exchange optical network alarm information is finally realized.The experimental results show that the proposed method has a short push time,high working efficiency,and accurate real-time push of the optical network alarm information when the alarm information is pushed in real time.
