基于IPv4/IPv6双栈的企业网关中DHCP机制的研究与实现

摘 要：本文首先对企业网关系统结构的设计进行了简单的介绍，然后分别对IPv4、IPv6环境下DHCP协议的地址状态迁移与C/S交互过程进行了研究，最后然后结合两者的异同点，设计开发了一种适用于双栈网关的DHCP协议软件模块，经过实验与工程应用验证了该模块具有良好的稳定性和兼容性，拥有较大的实用价值。

Research and Implementation of the DHCP mechanism based on IPv4/IPv6 dual-stack enterprise gateway

Abstract: This paper give a brief introduction to the design of the system architecture of the enterprise gateway, then respectively studies the migrations of address-status of DHCP protocol and the interaction between client and server of DHCP protocol in the different environments of IPv4 and IPv6.Then combined with the similarities and differences between of them, design and develop a kind of software module about the DHCP protocol that applies to IPv4/IPv6 dual-stack environment. Experiments and engineering applications verified this kind of module has good stability and compatibility. It has great practical value .
