基于Spice协议的虚拟桌面视频分析与改进

Video Analysis and Improvement of Virtual Desktop Based on SPICE Protocol

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 matureand the desktop virtualization becomes a typical cloud computing application. Virtual desktop technology can effectively solve thoseproblems 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 willplay a guide role for the development of virtual desktop technology.
