基于IPv6的防火墙包过滤技术研究

摘要

As the network continuous develop ment, the current IPv4 protocol can not meet the development needs of network, it will gradually be replaced by next generation network (IPv6 network). IPv6 protocol relative to the IPv4 protocol has been greatly changed, if the varieties of firewall for the original IPv4 network fit for IPv6 network, the problem is needed to be studie. This paper analyzes the differences features and principles between IPv4 and IPv6 packet filtering firewall, for IPv6 mobility, it analyzes that how to communicate packet filtering firewall in IPv6.%随着网络的不断发展,IPv4协议已经不能满足网络的发展需要,将逐步被下一代网络(IPv6网络)所代替.IPv6协议相对于IPv4协议已经有很大的改变,对于原来IPv4网络下的各种防火墙是否还能适用于IPv6网络,是需要研究的问题.本文通过分析IPv4与IPv6的不同特性及防火墙的包过滤原理,针对于IPv6的移动性分析在IPv6的环境下防火墙如何通过包过滤技术进行通信.
