校园网IPv4向IPv6升级互通网关设计

Design of IPv4 /IPv6 Transition Gateway in a Campus Network

现有的IPv4网络资源已经不能满足规模的日益扩大和应用的不断增多的校园网络。作者通过IVI技术,设计了基于IVI技术融合DNSALG的IPv4/IPv6互通网关,详细分析了互通网关的原理、组成结构、设计原则以及工作过程,并对IVI网关的部署方式实施了介绍。通过该互通网关的使用,可以较好地满足校园网内部的纯IPv4网络和纯IPv6网络间的IPv4/IPv6互通需求,实现Pv4/IPv6协议之间的高效率、顺畅的通信。

Presently,the resource of Ipv4 network can not meet the need of campus with expanding scale and increasing number of users.An IPv4/IPv6 transition gateway based on IVI technology and DNSALG was designed.The principle,structure,design idea and operation process,as well as the arrangement mode of IVI gateway are described.This gateway can satisfactorily achieve the transition between pure IPv4 network and pure IPv6 network in a campus network with high efficiency.
