Abstract

Abstract: Based on the technology of network measurement and theory of complex network，Internet physical properties in Chinese Mainland is measured and analyzed in this paper.Firstly，research conditions of Internet network measurement is described，then Internet physical properties parameters，which are Internet diameter，cluster coefficient and degree distribution，are formally defined with quantitative analysis.Researchers use 18 months to measure and analyze Internet physical properties in Chinese Mainland.They calculate the un-weighted Internet diameter is 14.9，cluster coefficient is 0.32，degree is 5.68.Lastly，it introduces weighted Internet diameter and calculates the weighted Internet diameter is 15.6±3.1.The analysis of weighted Internet diameter provides a more accurate perspective on the structure of Internet.

Key words: Internet diameter, cluster coefficient, degree distribution, Internet features, network measurement, complex network

摘要： 结合网络测量技术和复杂网络理论对中国大陆地区Internet物理特征展开测量与分析。首先阐述了Internet网络测量的研究现状，然后形式化地定义了Internet物理特征的3个重要表征量：Internet直径、聚类系数、度分布。其次，研究人员经过18个月的测量与分析中国大陆地区Internet物理特征，计算出未加权Internet直径是14.9跳，聚类系数为0.32，度值为5.68。最后，对Internet直径进行了加权处理，计算出加权的Internet直径为15.6±3.1跳，加权后的Internet直径分布特征能更加精确地反映Internet特性。

关键词: Internet直径, 聚类系数, 度分布, Internet物理特征, 网络测量, 复杂网络
