摘　　要：随着互联网的高速发展,IPv6作为下一代互联网协议受到广泛关注。目前业界已对IPv6相关技术进行了一系列测试实验,IPv6也逐步从实验室走向现网应用。在IPv6的各类过渡技术中,DS-Lite技术是一种公认的中长期演进方案。对DS-Lite技术进行现网部署,并对关键环节技术难点实现突破,包括支撑系统的改造、运维流程的调整等,可为后续IPv6的规模商用奠定基础。主要针对DS-Lite过渡技术在运营商现网部署过程中遇到的业务实现、业务可靠性、运维流程等技术难点进行详细阐述,并提出可行的实施思路与解决方案。With the rapid development of internet,IPv6 as the next generation internet protocol has been widely concerned.At present,a series of IPv6 experiments have been done,and IPv6 technology has gradually been deployed from laboratory to the application.DS-Lite is recognized as a long-term evolution scheme.The deployment of DS-Lite was carried out,and breakthrough on the key technical difficulties was achieved,such as IT system upgrading,operation process adjustment etc,which may lay the foundation for the IPv6 scale commercial.Aming at the technical difficulties on DS-Lite network deployment,some feasible solutions were put forward.
