Abstract: This paper analyz paper connection theory of nodes for typical network protocol, finds the Internet macroscopic topology has a power-law topological duplication, and proposes a mathematical model of Internet macroscopical topology connection with the help of physical methods. Simulation result shows the evolution rule about time sensitivity and node-degree of the model has the same results at statistical results of practical network data which show network characteristics, and receives the essence of Internet macroscopical topological power-law evolution due to the grade principle theory of protocol design.

Key words: Internet macroscopic topology, mathematical model, power-law fractal

摘要： 分析典型网络协议节点连接原理得到Internet宏观拓扑具有幂律拓扑可复制性，借助物理学方法提出一种Internet宏观拓扑连接的数学模型。仿真结果表明，该模型的时间敏感性和节点度的演化规律与实际网络数据统计结果的网络特征相符，Internet宏观拓扑幂律演化的本质源于协议设计的等级原理。
