摘　　要：在大规模桌面虚拟化集群部署过程中,虚拟机镜像创建时,大量镜像数据在镜像服务器和计算节点服务器之间传输,下载速度直接影响着虚拟桌面的创建和更新速度。为了提高虚拟机镜像模板部署和系统的整体性能,从网络传输角度,提出一种基于BitTorrent的P2P技术提升镜像下载速度的方法。该方法在计算节点数量较多的情况下,能大幅提高镜像下载速度,从而保证镜像模板的快速分发,提升用户对桌面虚拟化系统的使用体验。In the process of mass desktop virtualization cluster deployment,when the image of virtual machines is being created,massive image data are transmitted between image storage servers and computing node servers,whose download speed directly influences the speed of creating and of updating the virtual desktop.In terms of network transmission,the paper proposes the technique of P2P based on BitTorrent to accelerate image download and to improve the deployment of virtual machine image templates and the performance of the whole system.The approach is able to considerably accelerate the image download when there are a comparatively large number of computing nodes,so as to ensure the rapid distribution of image templates and to refine the user experience in the desktop virtualization system.
