【摘要】 IPv4向IPv6过渡的基本技术包括双协议栈、隧道技术和NAT-PT技术。基于这三种技术派生出多种互通和转换机制。这些机制分为两类,一类是实现IPv4海洋中的IPv6节点之间的通信;一类是IPv6小岛与Ipv4海洋之间的通信。该文对这些实现机制进行了具体分析和比较。更多还原

【Abstract】 Dual stack,tunneling and NAT-PT are the three common-used transition technologies between IPv6and IPv4.Several transition mechanisms are derived from these basic technologies.These mechanisms can be classified into two sets.The first one is related to having IPv6communications among two or more IPv6islands isolated in the IPv4world.The second set is related to establishment of(or some sort of)communications between the existing IPv4world and the new IPv6world.This paper gives a detailed analysis and comparison to these mechanisms.更多还原
