摘要:

通过对网站信息传输速度数据连续6个月的采集,编制出中国31个城市节点间信息传输速度矩阵。运用因子分析法计算出各城市节点对应的综合得分,并划分出等级,进而对最优等级/最差等级所涉及的城市节点进行频次统计,以分析信息联系通达性的等级特征。通过传输速度的等级划分,揭示高速连接线路和较高速连接线路的空间特征,最后对若干影响因素进行解释。研究发现:城市节点的输出和输入速度不一致,输出最优节点都处于主干网或与北京直接相连,输入最优节点与主干网关系不密切,输出和输入最差节点多处在网络末端;互联网信息联系通达性与传统城市等级间的正向对应关系发生偏转,传统等级靠前的城市节点信息传输通达性较弱;影响信息联系通达性的因素包括网络设置与网络组织、信息化建设与城市等级、网络服务运营商及其互通等,互联网服务商的供给和用户需求的对接有待改善。

Abstract:

As a clear indicator, transmission speed has a significant effect on describing transmission accessibility of Internet information between the city nodes. Through the data of information transmission speed on the tachometer site, this article constructs the matrix of information transmission speed between the 31 cities nodes in China. It used factor analysis, to calculate the cities node corresponding composite scores and divide them into grades, to count the frequency the optimal grade/worst grade of city nodes, and to analyze the grade characteristics of information linkages accessibility. And then, through the hierarchies of the transmission speed, the spatial characteristic of the high-speed and higher-speed connection lines are revealed. Finally, several influence factors are explained. The research findings are as follows. The output speed and input speed city nodes is not consistent. The optimal output nodes are at the backbone or are directly connected with Beijing. The relationship between the optimal Input nodes and the backbone is not close. The worst output and input nodes are more at the net end. Forward corresponding relationship between Internet information transmission accessibility and the traditional city level changes. The information transmission accessibility of traditional high level city nodes is slow. The influencing factors of the information linkages accessibility include network Settings and network organization, information construction and city level, network service providers and communication, etc. The supply of docking Internet service provider and the demand of users needs to be improved. The cognition of information transmission rules can shed some light on Internet service providers, so that they could adopt flexible operation mechanism and service concept. It is practical significance to realize value docking between Internet service providers and users. Hereby, we bring forward the proposes: 1) The major networks should establish an overall scheme of network infrastructure, network framework between major networks, and establish end-to-end communication with its related regulations and standards, and solve the problem of the broadband resources waste and services quality. 2) The related administrative departments should further expand the Inter-Network broadband capacity in the poorer accessibility regions, solve the inter-network broadband occupation problems, and innovate the operation pattern between mobile and fixed Internet.
