NFV数据平面的网络性能优化技术

摘要

In recent years,network function virtualization (NFV) is arousing concern widely from both academia and industry due to its flexible deployment and low cost.However,the performance bottleneck becomes increasingly distinctive and hinders the progress of NFV technology.The major factors were studied which could seriously affect the performance of NFV data plane.Firstly,an analysis was conducted on the causes for various kinds of performance overheads.Then,the optimization solutions were summarized to mitigate these overheads.Finally,a brief introduction was made on two types of architecture,which could significantly improve the performance of NFV data plane.%近年来,NFV因为其部署灵活、成本低廉等优良特性,受到了学术界与工业界的广泛关注.然而,性能问题在NFV发展过程中变得愈加明显,逐渐成为制约NFV技术进步的主要瓶颈.针对影响NFV数据平面网络性能的主要因素进行了归纳概述,分析了NFV的性能瓶颈所在,并在此基础上进一步归纳了相应的优化方法.最后,简要介绍了当前比较成熟的两种系统架构,能够显著提升NFV数据平面的网络性能.
