Abstract

Abstract:

With the continuous development of cloud computing, cloud desktop solution is increasingly mature, becoming a typical cloud computing application case. Using virtualization technology to pool computational resources, cloud desktop delivery traditional desktop or application which is deployed in pooling computational resources up to polymorphous terminal through the network. Cloud desktop transfer protocol is one of the core technologies of cloud desktop and provides users with use experience which is close to traditional desktop PC operating systems. Compared with the traditional physical desktop PC, cloud desktop support for USB device is not mature yet. The USB device with its plug and play, fast data transfer rate and other significant advantages has become the most widely used computer peripherals interface. A key of cloud desktop user experience is to support the USB and other external equipment. Deploying USB redirection in the cloud desktop, when the USB device was physically connected on the client side, users can read and write data and operate USB devices normally on the Guest system, providing more for office demand and daily use. The cloud desktop and mainstream desktop transport protocol were introduced in this paper. USB redirection solution was studied and had been addressed basing on the SPICE open source desktop transmission protocol and USBRedir technology. The key principle and technology such as USB device virtualization framework, virtual multi-channel technology and USBRedir technology, were analyzed. Deployment and application of the USB redirection in the cloud desktop were briefly explained.

Key words: cloud desktop, SPICE desktop transport protocol, USB redirection, USBRedir technology, virtual multi-channel
