摘　　要：随着云计算的不断发展,虚拟桌面解决方案VDI日益成熟,桌面虚拟化成为典型的云计算应用。虚拟桌面技术能够有效地解决传统个人计算机使用过程中存在的诸多问题,降低企业的运维成本,受到业界的广泛关注。SPICE协议作为开源的虚拟桌面传输协议具有其独特的技术架构和应用特性,通过SPICE协议能够在服务器和远程用户终端上部署虚拟桌面,并提供性能比较好的用户体验QoE。但是,SPICE协议本身目前还存在许多不足之处,不能适用于带宽较低的网络环境。在讨论了虚拟桌面传输协议的原理以及影响虚拟桌面性能的因素的基础上,详细分析了SPICE协议的架构以及核心技术,指出目前SPICE协议的不足,并提出了保证QoE情况下的改进方案,对于当前桌面虚拟化技术的发展将起到一定的指导作用。With the continuous development of cloud computing,the virtual desktop solution becomes increasingly mature and the desktop virtualization becomes a typical cloud computing application.Virtual desktop technology can effectively solve those problems when using traditional personal computers and also reduce maintenance costs,which draws industries＇ attentions.As an open source desktop delivery protocol,SPICE has its own unique architecture and characteristics.Using SPICE protocol,virtual desktops can be deployed between servers and remote terminal clients with good quality of user experiences.However,SPICE protocol has its own drawbacks,and it is not suitable for low-bandwidth networks.Virtual desktop technology is introduced and the theories of virtual desktop delivery protocols as well as factors that affect virtual desktop performances are analyzed.Based on the analysis,the architecture of SPICE virtual desktop solution and its core technology are further analyzed.Finally the drawbacks of SPICE protocol are pointed out and some improvements methods without affecting QoE are proposed,which will play a guide role for the development of virtual desktop technology.
