摘　　要：通过介绍云计算现有环境下网络I/O虚拟化的架构模式,提出一种新的聚合方式来提高云计算环境下网络I/O虚拟化的效率。首先通过分析云计算环境下现有网络I/O虚拟化的过程,进行云环境下的联网性能评估,并在软件和硬件两方面,得出其网络I/O虚拟化的瓶颈。然后,通过提出基于I/O虚拟化的数据包聚合算法,进而大幅度提升云计算环境下网络I/O虚拟化的资源利用率,CPU利用率和内存利用率。最后通过包聚合标注工具,以矩阵的形式,证明该方法的效率。By introducing the architecture of network I/O virtualisation in existing environment of cloud computing, in the paper we propose a new aggregation approach for improving the efficiency of network I/O virtualisation under cloud computing environment. First, through the analysis of existing network I/O virtualisation process in cloud computing environment we evaluate the network connection performance in cloud environment, and find the bottleneck of its network I/O virtualisation in two aspects of software and hardware. Secondly, we propose the I/O virtualisation-based packet aggregation algorithm and then significantly improve the resources, CPU and memory utilisations of network I./O virtualisation under cloud environment. At last, we prove the efficiency of the aggregation method in the form of matrix with packet aggregation annotation tool.
