[Abstract]:As a global information network, the Internet has a profound impact on people's production and life. When users obtain information from the Internet, the server records the user's access behavior and generates the Internet log data. Internet log data contains a lot of spatial information. At present, the research on Internet log data mainly uses data mining, machine learning and other technologies to analyze and monitor user access behavior and system security. Combining the research of Internet log data with geographical space, and using the technical means and methods of GIS to mine the Internet log data in space, we can effectively obtain its implicit spatial rule. It not only provides a wider perspective and angle for the analysis of Internet log data, but also promotes the study of information geography with information flow as its research object, which has important theoretical significance and practical value. In this paper, the basic data of CN domain name server log data obtained from China Internet Network Information Center for 24 hours are studied, aiming at the characteristics of CN domain name server log data. To realize the massive data processing, geo-coding and spatialization of CN domain name server log data, and to carry out spatial analysis from three scales of global, regional and local, in order to expand the research field of information geography theoretically. The technical system of web log data processing and spatial expression is constructed in technology, and the reference is provided for the construction of network infrastructure in practice. The main research contents and conclusions are as follows: 1) combing the related theories of information geography, Internet DNS service and attribute data spatialization. The connotation and research direction of information geography are summarized. This paper summarizes the concept, architecture and working principle of Internet DNS service, and points out that the domain name server log data has the characteristics of structure and magnanimity. The meaning and basic method of attribute data spatialization are summarized. On the basis of theoretical combing, this paper constructs a theoretical system for analyzing the spatial characteristics of top-level domain name (TLDN) access space. (2) aiming at the structure of CN domain name server log data, Based on the characteristics of magnanimity and the shortcomings of traditional GIS in mass data processing, a massive data processing framework is constructed to achieve efficient processing of log data. After extracting the geographical information from the log data and analyzing the factors affecting the spatial distribution of the access amount, the spatial method of CN domain name server log data is designed and realized. The spatial analysis of CN domain name server log data is carried out at the three scales of region and local area, and the spatial distribution pattern of the traffic volume of network service under CN domain name is revealed. The reasons for the formation of this distribution pattern and the problems reflected are explored. These results will provide reference and guidance for the future development of Chinese language network in China and even the world.
