探讨IPv6协议的双栈技术研究与应用

Research and Application of Dual Stack Technology of IPv6 Protocol

在IPv4协议已不满足于现如今环境下,本文对IPv4过渡到IPv6网络协议进行了技术阐述,并且提出了双网络协议并存的双栈技术,层次分析了双网络并存结构,主要分为核心层、汇聚层、接入层3个层次,相比于单一网络协议,在改善与升级中,只需要改变汇聚层以及接入层,增加这两层交换机的数量,而核心层与原来相同,仍然为两台双栈万兆核心交换机组成,通过对IPv6路由和IPv6地址的设计,提出了IPv4和IPv6双栈的技术方案,希望能为IPv4和IPv6双栈的发展提供一定的理论依据。

Since IPv4 protocol is not satisfied with the current environment,this paper describes the transition from IPv4 to IPv6 network protocol,proposes a dual stack technology with dual network protocols,and analyzes the dual network coexistence structure hierarchically,which is mainly divided into three layers:core layer,convergence layer,and access layer.Compared with a single network protocol,only the convergence layer and access layer need to be changed,in the process of improvement and upgrade,increase the number of switches in these two layers,and the core layer is the same as the original,which is still composed of two dual stack 10GbE core switches.Through the design of IPv6 routing and IPv6 address,a technical scheme of dual stack IPv4 and IPv6 is proposed,hoping to provide a theoretical basis for the development of dual stack IPv4 and IPv6.
