摘要
研究了Internet的物理量表征问题。以海量数据分析为基础,首先形式化定义表征Internet空间效能的物理参量——IP基密度,然后拟合出IP基密度基于时间维演化的数学模型。并从定性、定量、收敛性、拟合准确度及模型预测准确度等方面,对模型进行了评价。最后使用模型对较远未来网络情况进行了预测,重点预测并得出2008年8月北京奥运期间Internet高度可利用的结论。
Physical properties of Internet were discussed. Based on analysis of giant data, IP-based density, a physical property parameter of Internet spacial validity, was firstly formally defined. Then a fitting model of density was generated by GA. What＇s more, the fitting model was evaluated in several ways such as quantitative and qualitative analysis, fitting and forecast correctness of the model. Condition of Internet in the future, especially in Aug. 2008 when Olympic Games will be held in Beijing, was forecasted by the model and a result was yielded that Internet in August 2008 will be highly available.
