摘要
随着IPv4地址资源的逐渐枯竭,如何引入IPv6是电信运营商非常关注的问题,其中非常重要的问题就是IPv6的引入对接入网的影响以及接入网向下一代互联网演进的方式。本文首先分析了IPv6对接入网的影响和要求;然后结合现有接入网的设备现状,提出了接入网支持IPv6业务的2个主流方式:透传方式和IPv6感知方式;最后,提出了电信运营商接入网面向下一代互联网的演进策略。
Along with the gradual depletion of IPv4 address resources,how to introduce IPv6 is a major concern of telecommunication operators. Especially,the most important problems is the affect of introducing IPv6 on the access network,and how access network evolves into the next generation Internet. This paper first analyzed the affect and requirements of IPv6 on the access network. Then with consideration of current status on the access network equipment,two main methods to support IPv6 services： IPv6 transparent and IPv6 aware,are presented. Finally,the evolution strategies of the access network targeted to the next generation internet are shown.
