基于Spice协议的虚拟桌面视频分析与改进

摘要

随着云计算技术向实际应用转化的不断发展,桌面虚拟化VDI技术的日益成熟,作为云计算典型应用的虚拟桌面解决方案已逐步被人们接受和认可.传统计算机使用过程中的一些问题能被虚拟桌面有效解决,使用虚拟桌面能降低企业的能耗和IT运维成本.论文分析了SPICE协议的架构以及它采用的视频传输和压缩机制,指出目前SPICE协议在视频处理方面的不足,并提出了改进方案,对于桌面虚拟化技术的应用有一定的指导作用.%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. This the-sis discusses the architecture of SPICE virtual desktop solution and analyzes its video transmission and compression mechanisms. Fi-nally the drawbacks of SPICE protocol in video processing are pointed out and some improvements methods are proposed,which will play a guide role for the development of virtual desktop technology.
