摘要本方案主要完成校园网络的设计与实现。论文主要介绍校园网设计的需求分析，确立建设校园网的目标，依照标准的设计原则，设计出校园网络的结构及解决方案。本校园网采用通用的分层设计方法，将校园网络分成三个层次：核心层、分布层、访问层。建设一个高效安全的局域网并接入互联网，校园网对外提供Web、FTP 等数据服务，并且使每台电脑都能够访问互联网。采用 Cisco 的网络设备，把校园网内每个部门都设计成一个子网，规划每个部门的 IP 地址，设计网络拓扑图，配置网络的交换模块、广域网接入模块、服务器模块和远程访问模块。关键词：校园网 虚拟局域网 拓扑图 Cisco 网络设备Abstract The main campus network design and implementation. The paper mainly introduces campus network design requirement analysis, establish the goal of building campus network, according to the standard of design principle, design of campus network structure and solutions. The network layer by the general design method, will be divided into three levels: the campus network convergence layer, core, access layer. Building a high security of campus network and provide access to the Internet, Web, FTP data services, and make every computer can access the Internet. Using the network equipment, Cisco network engineering design methods, the campus every sector within a subnet, planning and design of each department, designing the IP address of the network topology configuration of network, the exchange of module, wan access module, the server module and remote access module.Key words: Campus network Virtual LAN Topological graph Cisco network equipment一、 网络设计原则和需求分析（一）校园网络设计原则1、实用性与先进性 根据学校实际情况和特点，在设计中特别强调实用性与先进性的结合，应采用成熟的网络技术，保证校园网实用；跟踪国际网络技术的新发展，设计技术先进的网络。在保证校园网可靠、实用、先进的基础上，可以提供研究先进网络技术的科研环境，方便学校的科研与开发。 2、开放性与标准化 整个校园网的...
