摘要
在信息产业蓬勃发展的今天,信息成为社会经济发展的核心因素,信息化已经成为当今世界的潮流。近年来国家加快改革教育体制,以教育为立国之本,建设一个高度发达的国家教育体系。
校园网是Internet技术在教育机构的一个应用。它是指在学校范围内,在一定的教育思想和理论指导下,为学校教学,科研和管理等教育提供资源共享,信息交流和协同工作的计算机网络。随着网络的逐步普及,校园网络的建设是学校向信息化发展的必然选择,校园网网络系统不仅为现代化教学、综合信息管理和办公自动化等一系列应用提供基本操作平台,而且能提供多种应用服务,使信息能及时、准确地传送给各个系统。校园网、建设中主要应用了网络技术中的重要分支局域网技术来建设与管理的。校园作为一个特殊的网络应用环境,它的建设与使用都有其自身的特点。在选择局域网的网络技术时要体现开放式、分布式、安全可靠,维护简单的原则。校园网的建设主要应用局域网技术以及多媒体技术为主的各种网络应用技术。
校园网络建设的重点在于加强教学科研的管理、辅助教师生动的教学、激发学生自主学习。从长远来看,校园网的建设,其主要意义是有利于学校教学、科研的快速发展,它能使广大教师利用计算机网络环境进行教学,开展科研活动,进而提高学校的教学质量和科研水平,为培养面向世界,面向未来的高素质人才提供有力的保障。

In today's information industry booming, information has become the core of social and economic development, information technology has become the trend of the world. In recent years, the country to speed up the reform of education system, education is the foundation of the country, the construction of a highly developed national education system.
The campus network is one of the applications of Internet technology in educational institutions. It refers to the computer network which provides resources sharing, information exchange and collaboration in the school teaching, scientific research and management education, under the guidance of certain educational ideas and theories. With the gradual popularization of the network, the construction of the campus network is the school to the inevitable choice of the development of information technology, campus network system not only for modern teaching, integrated information management and office automation and other a series of applications to provide basic operating platform, and can provide a variety of services, so that the information timely and accurately transmitted to the various systems. Campus network, the main application of the network technology in the construction and management of an important branch of LAN technology. As a special network application environment, the construction and use of the campus has its own characteristics. In the choice of local area network technology to reflect the open, distributed, safe and reliable, and the principle of simple maintenance. The construction of the campus network is mainly applied to the local area network technology and multimedia technology based on a variety of network applications.
The key of the construction of campus network is to strengthen the management of teaching and scientific research, to help teachers' vivid teaching, and to stimulate students' autonomous learning. From a long-term point of view, the construction of the campus network, the main significance is conducive to the rapid development of school teaching, scientific research, it can make the majority of teachers use computer network environment for teaching, research activities, and to improve the quality of teaching in schools and scientific research level, for training for the world, facing the future of high-quality talent to provide strong protection.

校园网建设应该以应用为核心,在设计中充分考虑到教育管理和多媒体教学的要求,并且网络技术应该具有一定的先进性,同时还要为以后的扩展留有一定的空间。为此,该校校园网应达到以下要求:
1网络具有传递语音、图形、图像等多种信息功能,具备性能优越的资源 共享功能;
2 校园网中各终端间具有快速交换功能;
3 中心系统交换机采用虚拟网技术,对网络用户分类控制功能; 4 对网络资源的访问提供完善的权限控制;
5 网络具有防止及便于捕杀病毒功能,以保证网络使用安全; 6 校园网与Internet相连后具有“防火墙”过滤功能,以防止网络黑客 入侵网络系统;
7 可对接入因特网的各网络用户进行权限控制。 1.2网络设计原则
