IPv4与IPv6的互操作研究及网络实验

Research and Network Experiment on IPV4/IPV6Mutual Operation

IPv6是针对当前IPv4的地址空间不足和服务质量的缺陷而设计的一种新的网络协议类型。但是,现在IPv4的应用仍然占主导地位。在IPv6的网络流行于全球之前,总是有一些网络首先使用IPv6协议并希望能够与当前的Internet正常通信。为达到这一目的,必须开发出IPv4/IPv6互通技术以保证IPv4能够平稳过渡到IPv6,论文先从应用层的角度讨论了IPv4/IPv6的服务器与客户端的通信机制,然后利用模块编程技术打造一个具有路由公告和包转发功能的服务器,通过隧道技术使IPv6主机通过IPv4路由器进行通信。

IPv6is a new version of the internetworking protocol designed to address the scalability and service shortcomings of the current standard,IPv4.But the application of the IPv4still occupies the predominant position.Before the IPv6network is widely accepted,there are always some network s which use first the IPv6protocol and hope to communicate with current Internet.For this purpose,it is necessary to develop the IPv4/IPv6mutual communication technique to guarantee the IPv4can transfer to the IPv6smoothly.This paper first discusses the communication mechanism of IPv4/IPv6server and client in application layer,then create s a server sending router advertisement and transmitting packets by the module programming.It can make the IPv6host communicate with each other by the IPv4router with the tunnel technique.
