摘　　要：为了克服虚拟化网络环境中的资源占比不均问题,实现对动态资源结构体的合理化分配,提出基于云桌面技术的虚拟专用网络动态资源分配方法。连接开源型云计算平台,按照KVM虚拟化应用需求,设置独立的Spice桌面传输协议,完成基于云桌面技术的虚拟专用网络搭建。在此基础上,选择合理的动态网络基站,通过虚拟化网络切换的方式,建立必要的分配效用函数,实现虚拟专用网络动态资源分配方法的正常应用。对比实验结果表明,与基于边际效用的网络资源分配模型相比,应用所提的动态资源分配方法后,一个传输周期内的网络数据转发极值达到8.7×10^(15) T,而数据节点占比率却仅为65%,能够加强虚拟化网络环境中的资源占比均衡性,实现动态资源结构体的合理化分配。In order to overcome the uneven proportion of resources in the virtualized network environment and realize the rational allocation of dynamic resource structures,a virtual private network dynamic resource allocation method based on cloud desktop technology is proposed.Connect to the open source cloud computing platform,set up an independent Spice desktop transmission protocol in accordance with the requirements of KVM virtualization applications,and complete the construction of a virtual private network based on cloud desktop technology.On this basis,a reasonable dynamic network base station is selected,and the necessary allocation utility function is established through the way of virtualized network switching to realize the smooth application of the dynamic resource allocation method of the virtual private network.Comparative experiment results show that,compared with the network resource allocation model based on marginal utility,after applying the proposed dynamic resource allocation method,the network data forwarding extreme value in a transmission cycle reaches 8.7×10^(15)T,while the proportion of data nodes is only 65%,which can strengthen the balance of the proportion of resources in the virtualized network environment,and realize the rational allocation of dynamic resource structures.
