互联网拓扑结构的描述是一个重要的开放性问题，近期随着无标度网络的引入而得到解决。我们关注三年内真实互联网地图的拓扑和动态特性。我们研究高阶相关函数以及若干量的动态变化。我们发现互联网的特点是节点之间存在非平凡的相关性以及不同的动态机制。我们指出节点层级和老化在互联网结构和增长中的重要性。我们的研究结果为互联网演化的现实建模提供了线索。
The description of the Internet topology is an important open problem, recently tackled with the introduction of scale-free networks. We focus on the topological and dynamical properties of real Internet maps in a three-year time interval. We study higher order correlation functions as well as the dynamics of several quantities. We find that the Internet is characterized by nontrivial correlations among nodes and different dynamical regimes. We point out the importance of node hierarchy and aging in the Internet structure and growth. Our results provide hints towards the realistic modeling of the Internet evolution.
