摘　　要：网络功能虚拟化(network functions virtualization,NFV)利用虚拟化技术将网络功能从专用硬件中分离形成虚拟网络功能,然后把虚拟网络功能映射到通用服务器、交换机或者存储器中,能有效地降低网络投资成本和运营成本,并提高网络服务部署的灵活性。网络功能虚拟化资源配置是实施NFV需要解决的一个关键问题。为深入剖析网络功能虚拟化资源配置,介绍了NFV的体系结构,重点阐述了资源配置的三个阶段及资源配置的优化,最后对高效资源配置面临的挑战和有价值的研究方向进行了思考,为NFV的研究提供参考。Network functions virtualization（NFV） utilizes virtualization technology to separate network functions from dedica- ted hardware into virtual network functions, and then maps virtual network functions to general-purpose servers, switches or storage. NFV has the potential to lead to significant reductions in capital expenditure （CAPEX） and operating expense （OPEX） and improve the flexibility of the deployment of network services. One of the key problems that need to be addressed to implement NFV is NFV resource allocation. In order to deeply analyze NFV resource allocation, this paper introduced the architecture of NFV, focused on the three stages of resource allocation and optimization of resource allocation. Finally, the challenges and the valuable directions of efficient resource allocation were also thought as references for the research of NFV.
