【摘要】 IANA可分配IPv4地址池已全部耗尽。向IPv6过渡已经迫在眉睫。由于IPv6、IPv4协议的不兼容,十年来,IETF逐步提出了双栈、隧道和翻译技术以解决IPv4向IPv6过渡的问题。本文在对比多种翻译技术的基础上,介绍了基于无状态翻译的IPv4/IPv6过渡技术(IVI),该技术使用运营商地址前缀、进行无状态的IPv4/IPv6地址映射和协议翻译,实现了纯IPv6网络与全球IPv4/IPv6互联网的双向透明互访。该技术已经形成IETF系列标准,在CERNET/CERNET2上部署实施,并可以应用到运营商网络、数据中心、各行业专网等不同的应用场景,具有可分步实施、可扩展、安全性好、可持续发展的特点。
【Abstract】 The IANA IPv4 pool was empty in February 2011 and deploying IPv6 is very critical for ISPs,ICPs and enterprise networks.However,IPv4 and IPv6 are not compatible protocols and transition from IPv4 to IPv6 must use dual stack,tunneling or translations technologies which are proposed by IETF.In this paper,we compare different translation technologies and introduce stateless translation(IVI).IVI uses network specific prefix and translate IPv4/IPv6 addresses and IPv4/IPv6 headers in a stateless fashion.IVI can support bidirectional initiated the communications between IPv4 and IPv6 networks and is becoming IETF’s standards.Then we present the concepts of IVI and the CERNET/CNGI-CERNET2 as well as ISP deployment examples. The testing and deployment results indicates that IVI is a scalable,incremental deployable and secure technology and can be used to achieve smooth transition from IPv4 to IPv6.
