【摘要】 针对NewClass数字语言实验室设备成本高、各终端管控性能差的问题，设计NewClass数字语言实验室云桌面系统。系统包含云终端、云桌面、云服务器三个主要部分，将教育桌面云模式接入系统内，使所安装目标有效运行，并通过云终端呈现运行结果；采用Phantosys虚拟机软件，进行本地数据缓存、网络传输协议优化和镜像文件传输，实现服务器硬盘存取管理；以统计学为基础，构建并发多媒体负载使用控制模型，避免多人使用下的云桌面功能碰撞现象。应用测试结果显示，该系统可降低运行成本，具有较快的响应速度，以较快速度管控虚拟桌面。更多还原

【Abstract】 Based on the problems of high equipment cost and poor management and control performance of each terminal in NewClass digital language laboratory, the cloud desktop system of NewClass digital language laboratory is designed. The system includes three main parts, which includes cloud terminal, cloud desktop and cloud server. The education desktop cloud mode is connected into the system to make the installed target run effectively, and the running results are presented through the cloud terminal. The virtual machine software of Phantosys is used to implement local data cache, network transmission protocol optimization and image file transmission to realize the access management of server hard disk; On the basis of statistics, this paper constructs a concurrent multimedia load control model to avoid the collision of cloud desktop functions under the use of multiple people. The application test results show that the designed system can reduce the operating cost, has faster response speed, and can control the virtual desktop at a faster speed.更多还原
