云GIS环境下负载均衡算法研究

摘要

根据对云GIS案例的分析,从概念、软硬件拓扑结构、数据类型、请求处理流程等方面分析相关特点和问题,提出建立针对云GIS的负载均衡模型是整体提高云GIS性能的核心关键,并构建基于量子蚁群算法的负载均衡模型.通过云仿真技术构建云GIS平台,对模型进行仿真测试和压力测试,结果表明其性能有显著提高.%Based on the analysis of the Cloud-GIS case,a load balance model is provided to improve the performance of the Cloud-GIS,coupled with an quantum ant colony algorithm.Analysis is made on the characteristics and problems from some aspects,such as the concept,the topological structure of software and hardware,data type,request processing and so on.The cloud simulation technology used to support the cloud platform of GIS,has carried out the simulation test and pressure test for the model,results show that the performance is improved significantly.
