摘要
为了避免IP地址枯竭带来的影响,充分利用以IPv6技术为代表的下一代互联网的技术红利,世界各国都出台了IPv6发展战略,我国也出台了《关于下一代互联网"十二五"发展建设指导意见》等政策,明确了我国下一代互联网的发展目标。作为信息网络基础设施的有线电视网络正在加速向更加通用开放的IP技术过渡转型。由于IP地址资源不足及安全性等方面的问题,广电网络的业务发展受到严重的制约。此外,面临三网融合的激烈竞争,广电网络运营商迫切需要解决IP地址资源不足,以及IP网络安全性的问题。本文通过论述广电网络IPv6迁移需要解决的问题,分析了三种主流的过渡技术,梳理出广电网络演进的各个阶段,提出了广电网络实现平滑迁移的方法。
As the next generation technology, IPv6 would play an important part in the network evolution. Many countries have designed the IPv6 strategy. Our country released the relevance strategy as well. In the policy of ＂Guidance on the development and construction of the next generation Internet ＂12th Five-Year＂ ＂, the target was settled down, and the schedule was well planned. As a basic information infrastructure, the cable network is evolving into a more general IP technical system. Because of a shortage of IP addresses and security problems, the development of cable network services is limited seriously. Besides, in front of the fierce competition during the process of integration of three networks, cable network operators should upgrade the cable network more rapidly. In this paper, we talked about the problems ahead during the network transition. Three main transition technologies were analyzed briefly. We have defined three stages and the ways of the transition.
