摘要
针对复杂异构网络环境中故障定位难的问题,采用代理技术,分析视频专网服务质量(Qo S),提出了一种基于改进代码书的网络故障定位算法。该算法采用视频Qo S阈值进行故障事件检测,引入时间参数,建立具有三个维度参数的专网故障代码书,实现了视频监控质量评估与网络故障的快速定位。实验结果表明,该算法可实现故障事件实例检测,准确率比原有方法有较大提升,是一种有效的故障定位方法。
Considering the difficulty of fault location in the complex and heterogeneous network,using agent technology and analyzing video network quality of service（ Qo S）,this paper proposed a network fault location algorithm based on improved codebook correlation model. The algorithm used a video Qo S threshold for fault event detection,introduced a time parameter to establish an intranet fault codebook that had three dimension parameters,and achieved evaluation of video monitoring quality and network fault fast positioning. The experimental results show that this algorithm not only can realize the detection of fault events,but also improves accuracy and efficiency than the original method.
