在深入研究由因特网工程任务组(IETF)提出的从IPv4到IPv6过渡的3种机制(NAT-PT、隧道、双栈)的基础上,分别给出了NAT-PT和隧道的具体实现技术,并提出利用这2种技术的协同工作如何来组建IPv6网络,最后通过对具体案例的分析,显示其技术优势。
Based on the deep research on the three mechanisms (NAT-PT, tunnel and dual stack) proposed by the Internet Engineering Task Force (IETF) for the transition from IPv4 to IPv6, the specific implementation technologies of NAT-PT and tunnel are given respectively. And put forward how to use these two technologies to work together to build IPv6 network. Finally, through the analysis of specific cases, shows its technical advantages.
