Abstract:

With the

continuous development of cloud computing, the virtual desktop solution becomes increasingly

mature and the desktop virtualization becomes a typical cloud computing application. Virtual

desktop technology can effectively solve those problems when using traditional personal

computers and also reduce maintenance costs, which draws industries' attentions. As an open

source desktop delivery protocol, SPICE has its own unique architecture and characteristics.

Using SPICE protocol, virtual desktops can be deployed between servers and remote terminal

clients with good quality of user experiences. However, SPICE protocol has its own

drawbacks, and it is not suitable for lowbandwidth networks. Virtual desktop technology is

introduced and the theories of virtual desktop delivery protocols as well as factors that

affect virtual desktop performances are analyzed. Based on the analysis, the architecture of

SPICE virtual desktop solution and its core technology are further analyzed. Finally the

drawbacks of SPICE protocol are pointed out and some improvements methods without affecting

QoE are proposed, which will play a guide role for the development of virtual desktop

technology.
