| 摘 要： | 以某校园网为例,进行了复杂网络实证研究.介绍了网络通信和复杂网络的基本特征,在调查研究校园网的基础上,完成了其逻辑拓扑结构图构建,分析了各节点的出入度情况,给出了校园网的若干特点,证实了校园网具有复杂网络的显著特性:少数几个节点具有大量的链接,而大量的节点只有少数链接,有的甚至没有链接;节点度分布大致服从幂律分布.依据分析结果提出建议:学校网络中心应加强出入度数高节点的软硬件建设,以保证校园网的安全性和稳定性.

| Abstract: | An empirical study was given on Complex Campus Networks based on the campus network of some university.Some basic characteristics of the complex network and the network communications were introduced.A network topologic structure was established and their out-in degree of every node was analyzed based on investigation of the campus network.Some main characteristics of complex networks were given,in which a few nodes had a large number of links,other nodes had few Links,or even no links,and the degree distributions of nodes approximately obeys power-law distribution.According to these characteristics,the management is proposed that of the campus network should strengthen the large out-in degree node construction including soft and hardware to ensure the campus network safety and stability. |
