摘　　要：互联网宏观拓扑中涌现着既机械又灵活的结构秩序.明确该秩序的耗散过程及相关方面的研究,对预测网络拓扑演化的方向及再设计互联网具有重要意义.择取CAIDA机构IPv4、IPv6与AS级网络拓扑数据,对比分析网络结构秩序的耗散行为,并探讨网络结构秩序同网络规模及网络基本连通性的相关关系.结果显示3种网络均为兼具集权式秩序性与均权式无序性的耗散结构,且其秩序在耗散过程中不断演化;3种网络规模以及网络基本连通性与网络结构秩序呈正相关关系,说明网络结构秩序在互联网发展过程中逐渐耗散.Mechanical and flexible structural orders emerge in the Internet topology.The researches describing the dissipative structural order and related topics are very important in the redesign of the Internet,and it is also of great importance in the field of predicting the evolution of Internet topology.IPv4, IPv6 and AS-level network topologies data which authorized by cooperative association for Internet data analysis （CAIDA ）are used in this paper,and the relationships among the network structural orders and the size and connectivity of the network are discussed,the results show that all the 3 kinds of network are of dissipative structures,which behave both centralization and equalization,and their orders are continuously evolving in the process of dissipation.The positive correlativity among the network structural orders and the size and connectivity of the network size shows that the network structural order is gradually dissipated in the development process of the Internet.
