NFV架构及其优势挑战

NFV Architecture and Its Challenges

NFV即网络功能虚拟化,由NFVI、VNF、MANO三部分组成。其中NFVI为VNF提供虚拟化的资源,VNF以软件的形式实现网络功能,MANO是整个系统的管理和控制层。NFV有赋能网络,简化运维,快速响应网络变化及业务发展需求等优势,同时,NFV发展也存在诸多阻力,运营商将其推向商业化仍需要时间与过程。

NFV is network function virtualization,which consists of nfvi,vnf and mano.Nfvi provides virtual resources for vnf,vnf realizes network functions in the form of software,and mano is the management and control layer of the whole system.Nfv has the advantages of enabling network,simplifying operation and maintenance,responding to network changes and business development needs quickly.At the same time,there are many obstacles in nfv development.It still takes time and process for operators to commercialize nfv.
