| 摘 要： | 在研究网络透视方法时,为对网络拓扑结构中相关方面进行数据分析,提出了基于网络路由矩阵的度量方法.为寻找网络中重要链路和路径,分别对单链路和单路径度量进行定义;为发现链路间和路径间的相互关系,分别对链路间和路径间的相似度量以及它们的相异度量进行定义,并且分析各度量的性质并用OPNET仿真平台进行实验说明.该度量方法可以帮助网络研究人员根据实际情况选取网络重要位置部署性能监测点,同时可以用于分析网络链路间和网络路径间的依赖关系,并且评价网络透视方法的推断精确度.

| Abstract: | Metrics based on network routing matrix are proposed to analyze network data of topology in the field of network tomography.To find the important network links and paths,metrics of single link and path are respectively defined.To explore relationships between different links and between different paths,similarity and dissimilarity of links and paths are also respectively defined.Some properties of metrics are analyzed by experiment with OPNET.These metrics can help network researcher place nodes of performance measurement on important location according to the real situation,analyze dependence of links and paths,and evaluate inference accuracy of some network tomography. |
