云计算环境下虚拟机网络性能优化研究

Research on Network Performance Optimization of Virtual Machine in Cloud Environment

研究云计算环境下虚拟机实现技术,比较分析三种虚拟机网络I/O实现模型,提出从软件和硬件两个方面优化虚拟机网络性能,搭建一个私有云平台并优化设计虚拟机网络I/O,测试表明经过优化设计的虚拟机网卡吞吐量和CPU利用率均优于普通网卡。

Studies the implementation of virtual machine in cloud computing environment, and makes a comparative analysis of the three virtual ma-chine network I/O implementation model, presents the optimization of virtual machine network performance from two aspects of software and hardware, by building a private cloud platform and optimizing the design of virtual machine network I/O. Test shows that the optimized design of the virtual machine network card throughput and CPU utilization rate is better than the common network card.
