互联网拓扑结构中的弹性网络特征

选取CAIDA机构数量级为107的互联网拓扑数据,对IPv4,IPv6与AS级互联网网络规模、标准网络结构熵、网络平均路径长度和网络度分布幂指数进行了分析.结果表明,互联网具有可扩展性与鲁棒性;互联网拓扑结构具有弹性网络特征,且随互联网的拓扑演化,弹性网络特征愈发明显.互联网弹性网络特征的发现,使借鉴生物学思想指导互联网宏观拓扑研究成为可能.

Elastic Network Characteristics in Internet Topology

Internet topology data whose magnitude is 10⁷ in CAIDA was adopted to analyze the Internet network size， standard Internet structure entropy， Internet average path length， power exponents of degree distribution of IPv4，IPv6 and AS level Internet. The results showed that the Internet has expandability and robustness. The Internet topology has the elastic network characteristics， and the elastic network characteristics become more obvious with the evolution of Internet topology. The discovery of the Internet elastic network characteristics makes it possible for reference to biological macro guidance Internet topology research.
