摘要

虚拟化技术的兴起，打破了网络设备的传统形态。电信运营商期望在通用硬件架构上部署NFV，以降低CAPEX和OPEX成本，提升运营效率，实现快速提供新服务的能力，提升运营商收入。但是，NFV虚拟化技术有其独有特点，若在政企宽带拨号上网类业务中使用与传统网络设备相同的部署和配置方式，会引发公网IPv4地址的大量消耗，提出在NFV环境中引入NAT444作为解决方案，并对部署、溯源方式进行了研究。

Abstract

With the boom of NFV technology

the traditional network hardware was being replaced.For telecom operators

NFV was expected to deploy on the universal server

which could reduce the CAPEX and OPEX

improve operational efficiency

achieve rapid deployment of new service

and ultimately increase the operator's revenue.However

NFV had its unique characteristics

which would consume a large amount of public IPv4 addresses if we used the same deployment and configuration as traditional network hardware in the scenarios of enterprise PPPoE dial-up network.NAT444 was introduced in NFV environment as a solution

including the deployment and traceability system.
