摘　　要： 20世纪80年代以来,世界上几乎所有发达国家都已相继建成了国家级的教育和科研计算机网络,并成为这些国家教育和科研工作最重要的基础设施,从而促进了其教育和科研事业的迅速发展。我国政府高度重视教育信息化工作,从1994年起开始投资建设中国教育和科研计算机网络/(China Education and Research Network,简称Cernet/)。在Cernet建设工程的推动下,我国的校园网建设呈现出了突飞猛进的发展势头。建立一个什么样的校园网,怎样建网,如何高效发挥校园网的作用,如何组织、建设和管理校园网上的信息资源,这些都是我们急需认清和解决的问题。 本文以广州市医药学校校园网系统设计与实现为背景,从校园网系统的概念及相关网络技术入手,比较详细地论述了医药学校校园网系统设计与实现的整个过程。论文先从介绍校园网的相关概念及建设校园网的重要性出发,结合对广州市医药学校校园网的组网需求分析,提出了网络设计的基本目标和原则;然后由校园网系统的需求分析入手,详细的分析网络系统的基本技术,如网络结构、传输介质、三层交换技术等,它们都是本设计的重要理论基础,并从适用和实用的角度重点论述了广州市医药学校校园网系统的总体设计、结构选型、网络层次结构、VLAN技术、设备选型以及综合布线系统等,对网络设计以及网络测式与试运行等方面进行了比较详细、全面的介绍,其目的是要建设一个先进、合理、实用的校园网系统。最后对系统的设计与实施进行简单总结,并提出工程过程中出现的问题。 Since 1980’s, the national wide education and scientific research networks have been set up one after another in many developed countries, and have become the most important state infrastructures in these fields and greatly promoted the rapid developments there. In China, the government has paid great attention on the educational informationization. Since 1994 we began to invest and set up the China Education and Research Network /(short for CERNET/). With the promotion of this program, the constructions of Campuses Networks in our country have been developing rapidly. But what campus networks shall we set up? How to put in into practical use with high efficiency? And one thing more, how to organize, construct and manage the information resources on a campus network? All these issues still remain problems for us to recognize and solve. In this thesis, the author tries to describe in detail the whole process of the design and construction of the campus network of the Guangzhou Pharmaceutical Vocational School /(GZPVS/), with the view of the concept of the system and its related network techniques, and based on the backgrounds of its design, construction and practical use. First of all, the thesis starts with the introduction of its importance and the related concept, combined with the analysis of the needs and requirements of the school for this system. Further, it puts forward the basic objects and overall principles. And then in the way of analyzing the requirement of this system it introduces in detail the basic techniques, the structure of the network, the transfer medium and the three layers exchange techniques etc. All these form the theory basis of the system’s design. And at the same time, the emphasis is put on the system’s applicable and practical qualities, by describing this network in terms of its design, structure style, network level structure, VLAN technique, sorts of equipments and structured cabling system. Consequently, a clear introduction of the whole system is given in detail in order to achieve the result for building an advanced, reasonable and practical campus network. At last, a brief summary is given on the design and implementation of the network, as well as the problems observed when the network was constructed.
