IPv6-only网络互通技术

[摘要] 对IPv6-only的网络互通技术从过渡技术、访问场景、应用需求3方面进行分析，对网络构建从应用、数据、状态、操作系统4个维度进行探讨。对IPv6-only网络访问IPv4 internet这一典型场景，采用NAT64/DNS64翻译技术进行系统构建，从操作系统、浏览器、网络应用（网页、即时通信、流媒体）等方面进行测试，并基于测试结果对IPv6-only的实际部署进行讨论。

[Abstract] In this paper, we analyze IPv6-only interoperability in terms of transition technologies, visiting scenarios, and application requirements. We also analyze network construction in terms of applications, data, state, and OS. We propose a practical system for accessing IPv4 internet from an IPv6-only network. This system uses NAT64/DNS64 translation technology. We test the OS, web browser, and Internet applications such as web sites, instant messaging, and streaming in this system. We use these test results as the basis for a discussion on the practical deployment of IPv6-only network.
