IP城域网NAT444部署方案探讨

Discussion of IP MAN NAT444 Deployment Scenarios

从IPv4向IPv6演进是一个长期过程,NAT444可解决当前电信运营商IP城域网IPv4地址短缺问题。本文介绍了NAT444技术原理、组成架构,并通过对NAT444关键部件CGN部署需要考虑的因素、方式、用户管理和用户溯源等进行分析,推荐了可实施的CGN部署方案,对于在IP城域网中部署NAT444具有一定的参考价值。

The evolution from IPv4 to IPv6 is a long term process. NAT444 can solve the current IPv4 address shortage problem in the telecornrnunieations operators IP metropolitan area network. The NAT444 technical principles and composition framework have been described, and lhe deployment of the key components CGN of NAT444 was introduced. The cteployment included factors needed to be considered. mode, user management and user traceability were analyzed, the implementation of the CGN deployment program was recommended. NAT444 has a certain reference value in IP metropolitan area network deployment.
