| 摘 要： | IPv6骨干网正在逐步建成并走向实用,纯IPv6的骨干网(如中国下一代互联网:CNGI)已经出现,而已有的大量互联网应用和服务仍存在于IPv4网络中,因此出现了大规模复杂IPv4网络通过IPv6骨干网互联的需求,然而目前没有满足这种需求的过渡机制.本文提出了一种基于IPv6的IPv4网络互联过渡机制框架,对4over6过渡机制框架进行了阐述和分析,并通过原型系统实现,对4over6机制框架进行了原理和功能验证测试.为减小路由开销,提出了ISP独立部署方案,增强了4over6机制框架的可实施性.4over6过渡机制框架具备对网络和端系统透明性、轻型和可自适应动态选路特性,网络管理维护负担小,可适应于大规模、复杂的网络互联等优点.

| Abstract: | As IPv6 networks rapidly deployed,native IPv6 backbones(such as CNGI) are emerging.However,vast applications and services still stay in IPv4 network.Thus,interconnection of IPv4 networks over IPv6 backbones is required.Unfortunately,there are no suitable transition mechanisms available to satisfy this requirement.We propose a 4over6 framework for IPv4 network interconnection over IPv6 backbone without explicit tunneling.The 4over6 mechanism is discussed and analyzed.Prototype implementation verifies the theory of the framework.ISP independent deployment scheme then is proposed which reduces the routing overhead and increases the practicability of 4over6 deployment.Being transparent to IPv4 and IPv6 networks,the light weight scalable 4over6 framework is fit for large-scale complexity network interconnection with automatic discovery and control. |
