1需求分析
1.1概述
目前，全球已掀起一股信息高速公路规划和建设的高潮，作为其雏形，国际互联网(Internet)上相连的计算机已近达数千万台，全球有数亿人在Internet上进行信息交换和各种业务处理。Internet上积累了大是信息资源，这些资源涉及人类面对和人事的各个领域。行业及社会公用服务信息。成为信息时代全球可共享的最大信息基地。
中国教育科研计算机网(CERNET)于1994年正式启动以来，已与国内若干所学校相连。为广大师生及科研人员提供了一个全新的网络环境。的确，随着信息技术的飞速发展，校园网的建设已经逐渐提到议事日程上来。但是我国目前大多数校园网上的应用还不丰富，与学校原有一些计算机业务系统还没有充分发挥，应用水平的低下是对校园网资源的极大浪费。只有提高校园网上的应用水平，才能切实提高学校各项业务水平，适应信息时代的要求。因而，如何利用当前先进的计算机技术与校园网资源，实现学校各项业务系统的集成，提高应用水平将是学校校园建设的下一个工作重点。校园网的建设可以方便老师的教学，及学校的管理。
1.2项目前景
校园网建设的目标应该既能满足学生即将进入社会，面临网络信息时代激烈
的知识竞争的需要，又能满足教师教学活动和研究人员迅速吸收最新知识、进行学术交流和创造的需要，同时还能达到在面积较大、环境较为复杂的校园内，进行行政、生活、教务管理以及开展多种业务活动的目的。这些需求使大学校园网应能适应多种不同数据传输类型，体现出不同的应用特点。同时，网络设计要尽量简单化、模块化 ，既可节省资金投入，又便于网络管理和升级。 随着该校信息化建设,教学资源整合,加强本地院校,远程院校,研究所,后勤部门的管理 ,急需重建整个大学的校园网络。能实现行政，教学，科研在网络上进行，实现接入国际Internet的信息化目标。
