Internet拓扑中的富俱乐部现象

The Rich-Club Phenomenon In The Internet Topology

Shi Zhou, Raul J Mondragon

摘要:

我们表明,互联网拓扑结构在自治系统(AS)的水平有一个丰富的俱乐部现象。富节点,即少量节点和大量链接,彼此连接得非常好。富俱乐部是一个核心层,我们使用富俱乐部连接性和节点-节点链接分布来测量。我们在AS之间没有任何启发式假设的情况下获得了这个核心层。富俱乐部现象是区分幂律拓扑结构的一种简单的定性方法,并为新的网络模型提供了一个标准。为了证明这一点,我们比较了AS图的富俱乐部与使用Barabási-Albert(BA)无标度网络模型,健身BA模型和Inet-3.0模型获得的网络。

英文摘要:

We show that the Internet topology at the Autonomous System (AS) level has a rich--club phenomenon. The rich nodes, which are a small number of nodes with large numbers of links, are very well connected to each other. The rich--club is a core tier that we measured using the rich--club connectivity and the node--node link distribution. We obtained this core tier without any heuristic assumption between the ASes. The rich--club phenomenon is a simple qualitative way to differentiate between power law topologies and provides a criterion for new network models. To show this, we compared the measured rich--club of the AS graph with networks obtained using the Barabási--Albert (BA) scale--free network model, the Fitness BA model and the Inet--3.0 model.
