基于IPv4网络的两种IPv6隧道传输方法

Two IPv6 Tunneling Methods Based on IPv4 Network

配置型隧道传输方法及自动型隧道传输方法是实现ＩＰｖ４基础网络设施向ＩＰｖ６网络迁移的两种有效方法。讨论了隧道位置、两类ＩＰｖ６地址，以及配置型隧道和自动型隧道的传输机制。此外，还详细提供了使用上述隧道传输技术的ＩＰｖ６数据报转发算法。

The configured tunneling and automatic tunneling are two efficient methods to implement the transition from IPv4 routing infrastructures to IPv6 network. This paper discusses tunnel positions,two kinds of IPv6 addresses, and both transmission mechanisms of configured tunnel and automatic tunnel. An algorithm that utilizes the above tunneling technology is also given to forward IPv6 datagrams.
