摘要： 研究了开放复杂系统Internet的有效性问题·首先给出了Internet网络空间和时间效能的一般性定义,然后形式化定义了两种效能的物理表征参量:网络比重和Internet网络访问直径,并进行了量化分析·通过公式推导证明了网络比重和访问直径二个物理参量之间的数学关系,并基于此形式化定义了Internet网络效能因子,将Internet网络的时间和空间效能联系起来,实现了对网络效能的综合评判·最后给出了网络效能因子基于时间维演化的数学模型,这将有助于对Internet未来发展情况进行预测和评价·

Abstract: As a hot topic in the field of complex networks, the problem of Internet validity is studied. General definitions of Internet space validity and time validity are given, then their physical characteristic parameters, i.e., networks density and Internet traveling diameter, are formally defined with quantitative analysis. Based on the mathematical relationship between the two parameters, which is derived from a series of known formulae, the definition of Internet validity factor is put forward as a parameter to connect Internet space validity with time validity so as to judge comprehensively the Internet validity. A mathematical model of validity factor based on time-evolvement analysis is thus given, which makes it possible to forecast and estimate the development of Internet in the future.
