摘要
运营商级NAT(CGN)是为适应运营商大规模的商业NAT部署,以在IPv6未大规模商用前,解决IPv4公网地址紧缺的问题。主要针对业界主流的CGN部署方案,多维度进行对比分析,通过建立用户模型,重点关注其网络建设成本,最后给出CGN部署建议。
CGN（Carrier-Grade NAT） is introduced to adapt to large-scale commercial NAT of operators, which would resolve the shortage of public IPv4 ad- dresses before IPv6 is in large-scale commercial use. This paper focuses on the industry mainstream CGN deployment scenarios with multi-dimensional comparative analysis through the establishment of user model, based on network construction costs. Fi- nally it gives recommendations for CGN deployment.
