文档介绍：华中科技大学硕士学位论文摘要随着网络的逐步普及,企业网络的建设是企业向信息化发展的必然选择,企业网网络系统是一个非常庞大而复杂的系统,它不仅为现代化发展、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。论文从嘉陵公司网络系统的总体设计出发,通过对主交换机、二级节点主交换机、路由器与ISP访问服务器配置与选型,从而选择出最佳的建立嘉陵公司网络的硬件系统的方案。具体针对企业网网络建设中的主要硬、软件系统进行了分析选型, 具体包括:主干交换机、二级节点主交换机、部门交换机、网络连接冗余、路由器、 ISP访问服务器、电缆、光缆、布线系统等硬件设备;以及应用软件、系统软件、软件防火墙、硬件防火墙等软件系统。随后,从主干网实施和综合布线子系统出发,以楼字自动化系统(BAS)、办公自动化系统(OAS)及通信自动化系统(CAS)作为设计依据,确定了采用以总体分布式、局部集中式相结合的布线方式,在实际运用取得了很好的效果。最后,从IP地址分配和域名管理、网络安全着手,运用硬件防火墙和软件防火墙相结合的方式,给出了一套完整的企业网络安全系统的解决方案。嘉陵公司网络建设过程用到的各种技术及实施方案将为企业网建设提供建设参考和实践指导。关键词:主干网络建设;CISCO交换机;ISP访问服务器;网络安全系统;域名管理华中科技大学硕士学位论文 Abstract Along with work gradually universal,developments ofthebusiness work are the inevitable choice that business enterprises turn to information the developments,the business networksystem is avery huge plicated system,it notonly develop,synthesize theinformation management forthemodernization with transact automation seriesapplication provide the basic operation terrace,but also can provide various application theservice,making information can on time,deliver accurately totheeach system. Papers from work system design,through tothe main switchboard,and themain switching node 2,ISP router andserverconfiguration and selection ofthe was the pany chosen tobuild work hardware system work construction inthe main hardware,and software systems for the analysis of models,including:specific trunk switches,2 nodes main switchboard,the department switches,work connectivity,the router,ISP access server,cables, fiber-optic System hardware;and the application software,system software,firewallsoftware,hardware firewallsoftware. Then,from the work and the implementation of integrated wiring subsystems,a building automation system(BAS).Office Automation System(OAS)munication Automation System(CAS)as adesign basis Distributed generally used to determine bination ofcentralized routing,In actual application has achieved good results. Finally,the a
