摘　　要：由于在IPv4向IPv6过渡的过程中,两种网络将共存,所以这两种网络之间的通讯是必须解决的问题。应用NAT-PT转换网关是解决这一问题的一种方法。首先对NAT-PT机制进行了研究,着重讨论了NAT-PT机制中的地址转换操作过程,然后对LinuxNetfilter功能框架作了介绍。最后提出了一种基于netfilter功能框架的NAT-PT转换网关的一种模块化设计。这种模块化的NAT-PT转换网关具有实现简单和易于进行进一步功能扩展的特点。Because of the coexistence of IPv4 and IPv6 networks, the communication between the networks of these two kinds is a problem must be solved during the transition from IPv4 to IPv6. The application of the NAT-PT translation gateway is one way to solve this problem. Firstly, the NAT-PT mechanism is researched, andtheprocessofaddress-translationintheNAT-PTmechanismisdiscussed as a special focus. Then the Linux netfilter function framework is introduced. Finally, a modularized design of the NAT-PT translation gateway is brought forward, which is based on the netfilter function framework. This modularized NAT-PT translation gateway is easy to implement and have the further function expansion.
