《论文_基于Boson Netsim 模拟器软件校园网 的实现 研究(定稿)》.doc

前 言 现代计算技术、通信技术和微电技术的迅速发展，互相渗透和结合，形成了信息技术的革命，其中一个重要的方面是计算机网络的产生和发展。从20世纪70年代开始建立的公共远程网，20世纪80年代迅速兴起的局域网，到20世纪90年代要加速发展的综合业务数字网ISDN；从微机网到巨型计算机网，从一个部门的局域网剑覆盖全国、全世界的大型网。计算机网络广泛用于科研、教育、管理、生产、商业以致日常生活等各个领域，它的重要性正被越来越多的人们所认识，成为信息社会中重要的基础设施。 在众多类型的计算机网络中，局域网络技术发展最为迅速，局域网络的应用最为普遍，局域网络的成品众多、市场广阔。20世纪80年代是局域网络大发展的十年，20世纪90年代是局域网络得到了更加迅速的发展，到了21世纪局域网络的应用更加的广泛。 随着科学的进步，信息的发展，校园网越来越受到各个学校的青睐。它对学校的信息管理，资源共享提供了平台。可以使学校的各个部门实现互联，更方便学校工作的开展。 本论文模拟一个校园网的环境，它的设计和组建方案，下面一一介绍。 目 录 摘要····························································· 1 校园网的概述·········································· 2 Boson Netsim 模拟器软件的使用·························· 4 校园网的整体结构·······································6 校园网的设计目标··································· 6 功能·································· 6 可缩放性······························ 6 可适应性······························ 6 可管理性······························ 7 成本有效性···························· 7 校园网的设计方法··································· 7 需求分析······························ 8 建立网络结构·························· 8 建立寻址和命名约定·····················8 准备硬件·······························8 实现、监视和管理网络···················8 校园网的布局········································8 校园网的拓扑图······································9 校园网的布线······································· 12 校园网的三级模式··································· 14 校园网的设计及应用···································· 15 Vlan技术及其划分方法······························· 15 Vlan技术介绍·························· 15 具体Vlan划分··························16 划分IP地址········································ 17 生成树协议及其应用································· 18 VTP原理及应用····································· 18 静态路由和动态路由································· 21 静态路由······························ 21 动态路由······························ 22 两者的区别···························· 22 集群技术的应用····································· 23 访问控制列表的应用································· 24 服务器的作用及其配置······························· 25 Web服务器···························· 25 FTP服务器···············
