摘要： 为了探究Internet拓扑动态节点演化特征的层级相关性，基于CAIDA项目授权的海量数据，结合网络科学的思想，分析了不同尺度下网络结构的演化机制.针对IP级与AS级拓扑，对层级与节点动态特性的相关性进行了分析，其中包括新生与消亡节点的动态变化比例、偏好依附、稳定连接数目等多个特性.结果表明:IP级拓扑节点的新陈代谢比AS级旺盛，IP级拓扑新生节点的非优先连接“偏好”比AS级稳定，新生连接中IP级拓扑的稳定连接数较多.IP级与AS级动态节点的演化有本质不同，为理解Internet的演化机制提供了基础.

Abstract: Introducing network science theories， the evolution mechanisms of different network scales were analyzed based on lots of data provided by the CAIDA project. As to the topologies of IPlevel and ASlevel， the correlation between the two levels and the characteristics of dynamic nodes were analyzed， including the dynamically changing proportion of birth/death nodes， preferential attachments and the number of stable attachments. The conclusions are as follows: firstly， IPlevel nodes are more active; secondly， the evolution of IPlevel nonpreferential attachments is more stable， and thirdly， the number of IPlevel stable attachments is much greater. The evolutions of the dynamic nodes in different measure levels are different in essence， which can provide a valid basis for understanding the Internet evolution mechanism.

Key words: network science, measurement level, preferential attachment, stable attachment, evolution
