运营商IPv4至IPv6过渡技术方案探讨

Discuss on operator transition technical scheme from IPv4 to IPv6

本文阐明了IPv4/v6过渡的必要性,对现有的基本过渡技术进行综述和比较。根据运营商实际网络环境分析已有的双栈技术和NAT444技术相结合的过渡技术,并在此基础上根据不同的场景分析不同的过渡技术,最终根据运营商的案例分析了部署CGN的过渡技术方案。

This paper summarizes the existing basic transition techniques, and clarifi es the need of the transition from IPv4 to IPv6. Then analyses the transition technology of the Dual IP Stack and NAT444 based on the operator’s actual network environment. According to the operators case and compare with other different transition technologies, the CGN deployment transition technology is discussed.
