SPICE协议虚拟多通道的实现

Realization of the Virtual Multi-channel SPICE Agreement

SPICE协议是开源的虚拟桌面传输协议,在SPICE服务器端和SPICE客户端进行交互通信,让用户获得比较好的桌面体验,但是SPICE协议在虚拟化多通道技术方面还是有一些不尽人意的地方。SPICE协议很难保证桌面应用程序的数据在虚拟通道中得到比例公平传输的机会,使得用户操作响应时间大、数据传输时延长、传输性能和服务质量降低,因此针对这些问题,论文提出一种新的动态优先级虚拟多通道管理技术,在每一个应用程序并发传输过程中可以根据自适应的复杂网络状况动态调整每个通道的传输优先级,提高虚拟桌面应用的实时性和用户的服务质量,使得用户能够获得更好的桌面体验。通过测试表明新的技术使得用户获得更好的桌面体验,也提高了系统的传输性能。

As an open source transfer protocol,SPICE protocol has unique technical architecture and application characteristics,virtual desktop can be deployed between servers and clients with good quality of user experience through the SPICE protocol.However,data is very difficult for SPICE protocol to get proportional fairness transmission chance.It also reduces the transmission performance and delays the user action response time.Due to these problems,dynamic priority virtual multichannel management technology is put forward based on adaptive network status.It can improve the real-time of virtual desktop applications and user service quality,and enable users to get a better desktop experience.
