21、不容忽视的问题。本文着重论述了校园网设计与建设过程中确立建设校园网的目标，校园网的技术方案设计，信息资源建设，应用软件的开发，网络管理与安全五个关键问题。校园网络作为学校重要的基础设施，担当着学校教学、科研、管理和对外交流等许多角色。校园网安全状况直接影响着学校的教学活动。在网络建成的初期，安全问题可能还不突出，但随着应用的深入，校园网上的各种数据会急剧增加，各种各样的安全问题开始困扰我们。互联网络的飞速发展，对校园网络中师生的生活和学习已经产生了深远的影响，网络在我们的生活中已经无处不在。但在享受高科技带来的便捷同时，我们需要清醒的认识到，网络安全问题的日益严重也越来越成为网络应用的巨大阻碍

22、，校园网络安全已经到-可编辑了必须要统一管理和彻底解决的地步，只有很好的解决了网络安全问题，校园网络的应用才能健康、高速的发展。我们应当全面考虑综合运用防火墙、加密技术、防毒软件等多项措施，互相配合，加强管理，从中寻找确保网络安全与网络效率的平衡点，综合提高校园网络的安全性，从而建立起一套真正适合学校计算机网络的安全体系。当今时代的知识经济的产生和信息技术的发展及Internet的全球普及化都决定了网络将成为信息时代的主要工具。随着计算机网络技术的发展，网络已成为人们交流信息的重要平台。基于因特网的网上教学具有时效性、共享性、交互性和个别化等诸多特点，因此它有着传统教学模式无法比拟的优点。它打

23、造了一种全新的教学模式，打破了传统教学模式在时间、空间上的局限，采用先进的教学手段和教学方法，大大提高了教学效率和教学效果，使教学活动上了一个新台阶。做好校园网络设计工作，是学校内部之间，校内和校外之间便捷沟通的关键。21 世纪校园网络的规模和应用水平将是体现学校教学环境和科研力量的重要组成部分，因此我们要利用校园内现有的条件，设计一个安全、统一的校园网络。大型校园网络设计：商务运作的大型校园网络在快速提升中寻求结构化的更新1.能处理高带宽的网络应用，例如语音，视频，IP 多播，提升共享的以太网或光纤的校园网骨干的容量2.能支持基于Novell IPX 的 NOVELL 网络,DECNET 协
