校园网络的搭建规划设计与实现 摘要 随着信息技术的高速发展，许多学校纷纷建立属于自己的校园网,将计算机引入教学、科研、管理等各个领域，从而引起了教学方法、教学手段和教学工具的重大改革，对提高教学质量，推动我国教育现代化的快速发展起着重要的作用。 本文在局域网技术和先进发展基础上，分析了建立校园网的意义，建设原则和目的，并详细阐述了其设计方案过程。文章从系统结构、网络方案、管理、布局等方面讨论了校园网络的设计方案。在网络设计中，详细介绍了网络拓扑结构、VLAN划分、IP分配、扩展访问、NAT配置。最后通过相关软件对网络进行管理以及实现网络的安全性。 本课题正是以本校的校园网为例，建设一个开放的、灵活的、先进的、可扩展的、易于管理的、高速网络的校园网，完全能够适应学校在相当长的一段时间里的使用要求。并且能够实现多媒体教学、网络教学、数据安全等各种网络服务，以满足现代化教学的各种需求。 关键词：网络拓扑，VLAN，IP，扩展访问，NAT Design and Implementation of the Campus Network ABSTRACT With the quick development of information technology, many campus network are constructed in which computers is adopted in teaching, scientific research, management and so on. It results in great innovation in teaching means and tools, and play an important role in implementation of modern education of our country. Based on local area network technology and advanced development, analysis of the significance of the campus network, construction principle and purpose, and expounds the design process in detail. The article from the system structure, network, management and layout of the campus network is discussed in aspects of design. In network design, the paper introduces the network topology structure, the VLAN dividing, the IP allocation, expand access, dynamic routing configuration, NAT configuration. Finally through the software of network management and network security. This topic is the word of the school campus network as an example, the construction of an open, flexible, advanced, scalable, manageable, high-speed network of campus network, fully able to adapt to the school for quite a long time of use requirements. And be able to realize the multimedia teaching, network teaching, data security and other web services, to meet the diverse needs of modern teaching. Key words: network topology, VLAN, IP, expanded access, NAT 目录 1 前言 1 1.1课题背景 1 1.2 目的和意义 2 1.3 系统设计思想 3 2需求分析 4 2.1 业务需求分析 4 2.
