The Research And Implementation Of Broadband Speed Test Platform Based On Webgis Visualization

With the rapid popularization of the Internet, the scale of Internet users gradually expands. It draws more and more people’s attention to the’truth’of broadband speeds. Facing the status of different standards for broadband speeds in our country, it is necessary to put forward a uniform standard and platform for broadband speed test, for testing and publishing broadband speed data over the country. By this way, relevant departments can manage domestic broadband speeds condition, so that ordinary people can enjoy the right of being informed of the broadband speed of the network they use. A broadband speed testing system based on WebGIS technology was designed and implemented in this paper. With the premise of ensuring data safe and reliable, the system collects nationwide broadband speed data and shows the country’s space-time broadband speeds distribution interactively on a statistical map.The main work of this paper includes the following two aspects:1) Research the key technologies involved in the process of broadband speed test system design and development, including Web security technology and WebGIS visualization techniques;2) Design and implement the broadband speed test system, which include data acquisition system (i.e. file upload subsystem) and broadband speed statistics displaying platform;3) Summarize the design and implementation work of medical retrieval system during the participation in TREC med track in my graduate period. The content covered include query expansion, query builder and search strategy design.This paper focused on the description of the design and implementation of broadband speed system. The paper first analyzed the demand and designed the overall framework for the entire broadband speed test system. Then it detailed the design and implementation of the data acquisition system and broadband speed statistics displaying platform. The data acquisition system uses HTTPS data transmission channel, and was designed detailed user authentication and access control mechanisms for. This paper designed a series of security measures in order to make the system work stably and data acquainted safe and reliable. The broadband speed statics displaying platform was secondarily developed on the basis of Baidu Maps API, to realize the function of WebGIS statistical map. This platform provides services of broadband speed statistics query and data spatial and temporal distribution displaying.
