为提高WebGIS系统中GIS服务器的处理能力,克服其计算和存储资源有限的缺点,增强容错性,在分析了传统WebGIS系统现状及存在问题的基础上,探讨了WebGIS系统中GIS服务器的负载均衡技术,设计了适合于GIS服务器的最少链接数负载均衡算法,并给出了工作流程。实验表明,本文提出的GIS服务器的负载均衡方法有效提高了WebGIS站点响应速度,解决了GIS服务器单点故障问题,为用户提供了更快、更好的WebGIS服务。
In order to improve the processing ability of GIS server in WebGIS system, overcome its shortcomings of limited computing and storage resources and enhance fault tolerance, based on the analysis of the status quo and existing problems of traditional WebGIS system, this paper discusses the load balancing technology of GIS server in WebGIS system , Designs the least link number load balancing algorithm suitable for GIS server, and gives the workflow. Experiments show that the proposed load balancing method of GIS server effectively improves the response speed of WebGIS site and solves the single point failure problem of GIS server and provides users with faster and better WebGIS service.
