摘要:

传统的下一代互联网方案IPv6通过横向扩展地址长度来扩展地址空间,因其不兼容IPv4导致长期难以普及。提出一种全新的解决方案,通过纵向扩展协议栈以无限复用整个IPv4地址空间,在扩展地址空间的同时可以很好地兼容现有IPv4网络,因此升级涉及面极小、成本极低,并可迅速部署完成。

Abstract:

Traditional IPng solution——IPv6, extends the address space by extending the length of the address laterally. Thus it's incompatible with IPv4 and difficult to promote. A new solution: reuse the IP addresses by extending the protocol stack longitudinally was presented. In this way, it can not only get very big address space, but also have very good compatibility with current IPv4 network. So the upgrade has minimal impact, requires a minimum investment, and can be quickly deployed.
