大学校园网架构

论文摘要

今天,信息化技术已成为公司企业、政府部门以及高等学府等机构非常重要的目标与愿望。随着全球新兴信息技术的发展,现代通信能够提供快速通信服务并提高个人通信效率,因此现代大学校园通信面对新的挑战,比如:需要提供一个信息网络能够支持个人需求并适应多元化的校园环境。一个新的网络架构成为校园网的骨干基础之一,它能够使教师,研究者,学生,管理者和员工组成一个社会群体更方便的进行教学、科研、学习并相互沟通。本文重点在于对校园网架构的定义以及校园网的基本组成部分的介绍。三个最重要的高质量的架构特征为:开放的网络架构、服务导向的特征以及基于包交换的IP网络。架构中四个重要的组成部分为:服务和网络管理、网络控制、中心交换单元和边缘接入。本文的理论贡献是提出大学校园网的参考模型架构,这个参考模型架构可以适用于建立一个健壮的灵活的网络能够满足下一代需求。结果的建立可以为建立现代校园网提供一个重要的参考指导。研究的校园网模型是可靠的、健壮的并且具有扩展性。
