摘　　要：文章提出了在跨越IPv4骨干网络进行IPv6用户接入时,实现穿越IPv4网络动态NAT节点隧道的解决方案,探讨了多层隧道嵌套及封装的技术原理及其应用特点,为IPv4向IPv6的网络过渡过程提供了一种在现有网络架构下平稳过渡的技术实现方案。文章提出的隧道嵌套技术已在中国南方电网CNGI驻地网实施过程中成功实现。This paper introduces the solution of crossing IPv4 NAT nods tunnel during IPv6 user access. It discusses the technical principles and application of multi-tunnel nesting and encapsulation, proposes a technical solution based on existing network configuration for the network transition from IPv4 to IPv6. The nested tunnel technology proposed in this paper has been successfully used in China Southern Grid.
