摘要
从生物进化的角度看待互联网演化,可以操控并引导网络演化方向,预测未来互联网结构与功能的发展趋势.择取CAIDA互联网全球研究机构2010—2014年互联网IPv4及IPv6全网探测数据.将Eigen对"生命特征"的定义与互联网宏观拓扑特征量的定义融合:以标准网络结构熵表征网络代谢行为;以1-25核网络度分布频度变化描述网络自复制特性;从网络平均聚集系数及网络平均路径长度的演化情况观测互联网自复制过程中出现的误差.对比分析互联网3种生命特征,发现IPv4与IPv6互联网均具有生命特征,且IPv6的生命特征较IPv4更明显,网络拓扑更具生命力.从互联网宏观拓扑中提取生命特征,是将生物学思想成功引入互联网领域的标志,这不仅对未来互联网研究提供更丰富的研究方法和更大的研究空间,更为有效地实现网络功能、预测并指导互联网发展提供理论支持.
The Internet is considered under the comparative process of biological evolution,which can predict the future of the Internet.The IPv4 and IPv6 whole networks data from 2010 to 2014authorized by CAIDA was adopted in this paper.On the basis of the previous researches,this study combines the Eigen＇s definition of‘vital signs＇ with the Internet topology characters：the metabolism of the Internet is measured by the standard Internet structure entropy,and the process of the Internet self-replication is represented by the various degree distributions of K-core networks,and the errors happened in the process of Internet self-replication is characterized by the changes in the evolution of the average clustering coefficient and average path length.The vital signs are observed in both IPv4 and IPv6Internet topologies,and IPv6 which has prominent vital signs behaves more vitality.The detection of the vital signs from Internet topology is a mark of introducing biological principles to researches on Internet topology successfully.For the further studies which are researched on or predict the dynamic of the Internet,the discovery in this study calls for attention to treat the Internet as a creature.It enriches the research methods and brings more space of development for the Internet researches.At the meantime,some advice for research direction about redesigning and rebuilding Internet is put forward in this study.
