ITU-TNGN和IPv6标准化、产业发展和可能的过渡方式

ITU-T NGN and IPv6 Standardization, Industry Development and Possible Transition

随着新业务和应用的出现,NGN和IPv6技术的发展和应用日益成为业界关注的焦点。本文对ITU-T NGN和IPv6的技术现状、标准化和产业化发展情况作了一个简单的介绍。文章还阐述了由IPv4网络向IPv6网络过渡的三种方式和运营商的可能选择。最后,文章对中国的以IPv6为基础的下一代互联网的发展进行了展望。

With the appearance of new services and applications, there is an obvious trend that ITU-T NGN and IPv6 will become the new and forward-looking technology for next generation network and Internet. This paper summarizes ITU-T NGN status and the international/domestic IPv6 standardization and introduces the global deployment of IPv6. This paper also discusses three IPv4-to-IPv6 transtion schemes and the possible choices for service providers. Finally, this paper presents the future scenario of IPv6 deployment in China.
