摘　　要：由于云数据中心处理的数据越来越多,云数据中心网络的负载越来越大,提高云数据中心网络的网络性能迫在眉睫。对于物理网络可以通过增加物理网络设备来缓解网络负载的增加,而虚拟网络是由承载在x86服务器上的软件来实现,因此提高虚拟网络的网络性能需要提高虚拟化软件性能,特别是虚拟化软件的数据包转发性能。为了提升OpenStack云平台的虚拟网络性能,本文深入研究了OpenStack云环境的虚拟网络构成。同时本文分析了造成云环境中虚拟网络瓶颈的原因,给出了提升云平台虚拟网络性能的具体方法。最后将原生OpenStack与优化后的OpenStack进行对比试验,优化后OpenStack网络二层和三层数据包转发性能可以提高6-7倍。Due to the increasing number of cloud data center data processing,network load of cloud data center is increasing.Improving the network performance of cloud data center network is imminent. The physical network can be increased through the physical network equipment to alleviate the network load increases.The virtual network is composed of a bearing on the x86 server software,so to improve perfor-mance can improve the performance of network virtual network virtualization software,especially the vir-tualization software packet forwarding performance. In order to improve the performance of the virtual net-work on OpenStack cloud platform,this paper studies the virtual network structure of OpenStack cloud environment. At the same time,this paper analyzes the reasons of the virtual network bottlenecks in the cloud environment,and gives the specific methods to improve the performance of virtual network. Final-ly,the primary OpenStack and the optimized OpenStack are compared,and the performance of Open-Stack two layer and the three layer network packet forwarding can be improved by 6-7 times.
