工业以太网中DHCP协议应用技术分析

随着网络规模的日益扩大以及人们对网络的移动性的要求越来越高，如果仍采用静态地址分配的方法进行IP管理，会给用户带来诸多不便，也给网络管理员增加很多工作量。采用动态主机配置技术进行IP管理、可以很好地解决这些问题。文章简要地介绍了DHCP技术的工作原理，以及DHCP技术在工业以太网中的应用。实践表明，DHCP技术对管理大规模的以及对网络移动性要求高的网络系统具有重要的意义。

Abstract: With the rapid expansion of the network scale and increasing requirement to network mobility, users will encounter several difficulties if traditional static address assignment is still adopted in IP management, and network manager will bear heavier load. IP management by Dynamic Host Configuration Protocol can commendably solve these problems. This paper presents the principle of DHCP technique and its application in Industrial Ethernet. It shows the significance of DHCP application on management of large-scale networks and on the network systems that require high mobility.
