| 摘 要： | 针对路由级Internet宏观拓扑结构的复杂性,分析了Internet拓扑结构的分形特征.利用κ-核解析将Internet拓扑分成不同的核,从内核至外核,分析了节点数目的增长、各核内节点的度分布以及谱密度分布,通过对各核拓扑图分别进行谱密度-特征值分布分析,发现各核分析结果表现出高度的一致性.这说明根据网络中心性定义的...

| Abstract: | Given the complexity of Internet macroscopic topology structure,analysis was conducted on the fractal characteristics of Internet topology structure at the router level.Internet topology was divided into different cores based on k-core decomposition.Node number from inner to outer core increased exponentially.Degree distribution in every core showed a high degree of similarity.Analysis was conducted on the spectral density distribution of the graph spectrum of the Internet topology structure.Analysis of the... |
