一种基于本地域的虚拟桌面架构设计与性能测试

Design and performance test of virtual desktop infrastructure based on local domain

针对目前由于虚拟桌面架构搭建不合理而导致的系统安全风险大、兼容性和拓展性不足等问题,对某图书馆机房的虚拟桌面框架结构及安全控制方案进行研究。在云计算环境下提出设计一种基于本地域的虚拟桌面安全架构,并对其运行模式、网关设计与交互、以及安全应用控制策略进行深入分析。同时,在该框架控制环境下,对所构建的模型进行性能测试和结果分析。研究结果表明:所构建的虚拟桌面架构可减少桌面使用过程中的额外消耗,启动时间比常规架构缩短了60%以上,所采用的网络拓扑结构以及三级访问控制机制,可有效降低系统安全风险,能够适应不同应用场景的安全需求,为高校机房安装部署虚拟化平台提供参考。

Aiming at the problems of system security risk,compatibility and expansibility caused by unreasonable construction of virtual desktop architecture,the virtual desktop architecture and security control scheme of the library room was studied in this paper.A virtual desktop architecture based on local domain was proposed in the cloud computing environment and its operation mode,gateway design,interaction,and security application control strategy were analyzed in depth.Furthermore,the performance test and result analysis of the model were carried out under the control environment of the framework.The research results show that the virtual desktop architecture could reduce the extra consumption in the process of using the desktop,and the start-up time was more than 60%shorter than the conventional architecture.The network topology and threelevel access control mechanism could reduce the system security risk effectively to adapt the security requirements of different application scenarios,and provide reference for the installation and deployment of the virtualization platform in university computer rooms.
