Codebook-based network fault diagnosis method

The invention discloses a codebook-based network fault diagnosis method, and the method comprises the steps: obtaining network fault monitoring data which comprises the statistics of an observable symptom corresponding to a network fault; and inputting the data into a codebook matrix optimized by an algorithm, and searching and analyzing by using a heuristic search algorithm to obtain a network fault diagnosis result under the monitoring data. By adopting the method provided by the invention, the codebook matrix can be efficiently constructed so as to carry out automatic diagnosis on the network. 本发明公开了一种基于码本的网络故障诊断方法，所述方法包括：获取网络故障监测数据，所述监测数据包括所述网络故障对应于可观测的症状的统计；将数据输入到一个经过算法优化码本矩阵中，利用提出的启发式搜索算法进行搜索与分析，得出该监测数据下的网络故障诊断结果。采用本发明方法，可以高效地构建码本矩阵以对网络进行自动化诊断。
