互联网拓扑建模-交互式增长模型
Towards Modelling The Internet Topology - The Interactive Growth Model
摘要:
互联网在自治系统层次上的拓扑结构(AS图)具有幂律度分布和层次结构。在本文中,我们介绍了互动增长(IG)模型的基础上,新的节点和新的链接的联合增长。这个简单而动态的模型与其他互联网幂律拓扑生成器相比是有利的,因为它不仅与AS图的度分布非常相似,而且与最近报道的富俱乐部现象测量的层次结构精确匹配。
英文摘要:
The Internet topology at the Autonomous Systems level (AS graph) has a power--law degree distribution and a tier structure. In this paper, we introduce the Interactive Growth (IG) model based on the joint growth of new nodes and new links. This simple and dynamic model compares favorable with other Internet power--law topology generators because it not only closely resembles the degree distribution of the AS graph, but also accurately matches the hierarchical structure, which is measured by the recently reported rich-club phenomenon.
