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 non-trivial 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.
互联网拓扑结构的描述是一个重要的开放性问题，最近随着无标度网络的引入而得到解决。我们关注三年时间间隔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几个量的动态变化。我们发现互联网的特征是节点之间存在非平凡的相关性以及不同的动态状态。我们指出了节点层次结构和老化在互联网结构与发展中的重要性。我们的结果为互联网演化的现实建模提供了线索。
