摘要
针对云端桌面只能对云终端USB设备进行基本的读写操作,无法共享USB设备诸多特性的不足,提出了一种新的USB设备重定向方案。该方案采用位于操作系统底层的虚拟外围总线驱动,通过IP网络扩展本地外围总线到虚拟桌面,保证了云端桌面应用程序和设备驱动程序能够通过现有接口访问云终端USB设备的所有特性,且I/O传输稳定、快速。
According that cloud desktop can＇t share the device-specific characteristics of USB devices,but can only share basic operations of read and write to cloud terminal,this paper proposes a new program on USB device redirection mechanism. Using a peripheral bus extension of the lowest layer in an operating system,expanding local peripheral bus over an IP network to a virtual desktop,it ensures that virtual desktop applications and device driver have permission to access diverse features of all USB devices with existing interface,with sufficient I / O performance.
