| 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Linux Netfiltr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.

| Abstract: | 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,and the process of address-translation in the NAT-PT mechanism is discussed 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. |
