摘要
随着IPv4地址即将耗尽,IPv4向IPv6过渡已成为必经之路,IPv4与IPv6将在很长时间内处于共存期。如何实现IPv4与IPv6共存期的应用互访和平滑演进是实现IPv4向IPv6成功过渡的基础。本文重点介绍了IPv4向IPv6过渡共存期可能存在的应用场景,并着重介绍了协议翻译技术、隧道类技术以及地址复用技术,并分析了不同技术的优缺点和适用情况。
With the exhaustion oflPv4 address, it has become a must to transit from lPv4 to IPv6. IPv4 and IPv6 will coexist for a long time. Therefore, how to achieve application transparency and smooth evolution for heterogeneous protocols is fundamental to achieve a success transition of IPv6. In this paper, we highlight the possible scenarios in the coexistence of IPv4 to IPv6 transition period. Besides, we also introduce transition technologies for different scenarios and analyze the advantages and disadvantages for different transition technologies.
