【摘要】 文章中在区分节点属性的基础上,基于自治系统级互联网拓扑中存在的经济关系对网络进行层次划分,从而构建出在全局和局部范围内都与实际网络数据极为相似的模型。该模型采用先确定层次划分、后确定连边策略的分步建模过程,不仅实现了模型参数的可测量,而且为互联网拓扑建模研究的进一步发展构建出一个较为合理的模型框架。更多还原

【Abstract】 This research focuses on hierarchy of the Internet and distinction of node attribute based on economic relationship between ASs,and finally proposes a model,which is quite similar to the real network both on global characters and local characters.This model adopts two steps strategy:confirming partition of hierarchy firstly and determining link strategy secondly.The model’s parameters are easily measurable and it represents a reasonable framework for further research on Internet topology modeling.更多还原
