摘要
以占领华尔街事件为例,研究社会事件和网络事件对Internet复杂拓扑连接的冲击,分析其拓扑在事件发展过程中的突变特征量,并剖析产生突变的原因.分别对各特征量与事件的发展趋势进行相关性分析,寻找相关度最高的特征量.将网络拓扑划分成低核、中核和高核3个层次,从核的角度分析网络各层次之间紧密程度的变化.结果表明,社会事件会通过搜索来改变网络路由路径,使得平均路径长度产生突变.通过分析各核边数的变化,得到以下结论:平均路径长度的变化是由低核至中、高核间的"长边"引起的.
Taking Occupy Wall Street as an example, the impact of social/network events was investigated on the complex topology＇s connection of Internet. The reasons why topology＇s features could suddenly change were analyzed while the events were happening. The relationships between each feature and the event＇s evolution were respectively discussed through correlation analysis to find out which feature correlated most closely with the events＇ evolution. The network topology was divided into three levels including low-core, medium-core and high-core, and the connection between the levels was analyzed in terms of the core. The result shows that the events can change routing paths by searching, thus makeing the average path length change sharply. The change in the number of edges in each core was analyzed, which showed that the change of the average path length was caused by ＂longer＂ edges.
