DHCP服务器规划与实现.doc

摘 要 DHCP是Dynamic Host Configuration Protocol的缩写，它是TCP／IP协议簇中的一种，主要是用来给网络客户机分配动态的IP地址。目前，校园网已成为高等学校的重要组成部分。随着校园网的扩大以及移动办公逐步要求的增加，如果仍然采用静态地址分配的方法进行IP管理，不仅使网络管理人员的工作量极大地增加，同时由于一些用户记不清自己的IP地址，在重新安装系统后乱用IP地址，造成IP地址冲突或无法正常上网，影响校园网用户的正常使用。为防止类似的事情发生，在校园网的IP地址分配可采用动态主机配置协议（Dynamic Host Configuration Protocol，DHCP），DHCP可自动将IP地址、掩码、网关、DNS分配给用户。 本论文详述了规划与实现的整个过程。并分为：需求分析，网络设计（网络拓扑结构），服务的配置与安装，网络设备的分析（设备间子系统），网络安全设计。最后对整个网络进行运行和调试。 关键词: 服务器，DHCP协议，网络安全，网络规划 Abstract Dynamic Host Configuration Protocol is short for DHCP, it is the abbreviation of the TCP/IP Protocol suite, it is mainly used to give network client allocation Dynamic IP address. At present, the campus has become an important part of institutions of higher learning. With the expansion of campus network and the increase of mobile office gradually requirement, if still using static address allocation methods for IP management, it make not only network management personnels workload greatly increased, and because some users dont remember their IP address, in reinstall system with IP address, causing confusion IP address conflict or cannot normal online, and affect the normal use of campus net users. To prevent similar things happen, in campus network IP address allocation can use the Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol, DHCP), DHCP can automatically will IP addresses, mask, gateway, DNS allocated to users. This paper gives a DHCP server planning and implementation of the entire process. And divided into: needs analysis, network design (network topology structure), service configuration and installation, network equipment analysis (equipment, network security between subsystems) design. Finally to the network operation and debugging.
