石家庄广播电视大学毕业论文校园网规划及相关技术姓 名：学号：学校名称：石家庄广播电视大学专 业：计算机与信息管理年 级:2012级日 期：2014.11.04摘 要本文以科技工程职业学院校园网规划和设计为背景,从相关计算机网络技术及校园网的作用入手,比较详细地论述了科工院校园网设计与实现的整个过程。论文首先简要介绍了Internet和校园网的概念,比较了各种组网技术的优缺点,并对科技工程职业学院校园网的组网需求进行了分析。通过对三层交换技术和VLAN的分析和应用,结合网络组网需求,设计了常用的核心层、汇聚层和接入层组成的三层网络结构模型,设置了8个汇聚区,采用星型拓扑结构组网,采用千兆位交换式以太网作为网络骨干,实现百兆到桌面。网络出口采用网通千兆和Cernet百兆的双出口设计。根据实际情况选用了ISCO WS-C3560G-24PS-S型三层交换机。为了承担网关和三层路由转发功能的重担。所以汇聚层交换机选用CISCO WS-C3550-24-SMI型的三层交换机。实现与PC机的连接，为用户提供大量端口。接入层交换机选用CISCOWS-C2950C-24型号的交换机。传输介质方面,采用了楼宇间、楼层间光缆传输和楼内双绞线传输结合的方式实现信息传输。最后,对于设备的调试和网络的维护进行了介绍。本文中参照了当前诸多校园网方面的相关组网形式和成熟的网络技术,在实际应用中,达到了预期效果。关键词: 校园网路由器三层交换机综合布线虚拟专用网AbstractBased on the engineering vocational college of science and technology campus network planning and design as the background, from the computer network technology and the function of campus network, more families and work institute campus network is discussed in detail the whole process of design and implementation. Paper first briefly introduces the concept of the Internet and campus network, compares the advantages and disadvantages of various network technologies, and networking needs of engineering vocational college of science and technology campus network are analyzed. Through the analysis of layer 3 switching technology and the WLAN and application, combined with the network networking requirements, design the common core layer, convergence layer and access layer three layer network structure model, set up eight funnel area, USES the star topology network, using one billion switched Ethernet as network backbone, correlates to the desktop. Export using netcom gigabit network and correlates Cernet double outlet design. According to actual situation to choose the huawei S8512, S6503 and S3600 switches respectively as core layer, convergence layer and access layer switches, huawei NE40 router as export router, wave series server as a host system and related configuration. Transmission medium, the optical fiber network for transmitti
