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,使企业内部实现互联互通,办公自动化,信息化,并且有利于数据交换、资源共享、打印共享;同时接入Internet,增加内部资源信息。 本论文主要阐述目前企业网的规划设计,通过对一个中型企业网的组建让大家更加了解企业网的原理,主要内容有:用户需求分析,网络设计原则,网络设备选型,网络规划拓扑,网络结构设计,安全性设计,IP地址规划,路由协议选择,无线局域网和VoIP部署,方案实施。整个企业网络在Cisco Packet Tracer上模拟实现,并测试通过达到预期效果。

Abstract
With the gradual popularization of the network, enterprise network construction is the inevitable choice for enterprise to the development of information technology, enterprise network system is a very huge and complicated system, it not only provides the basic platform for a series of application of modern development, integrated information management and office automation, and can provide many kinds of application service, make the enterprise internal achieve interoperability, office automation, informationization, and is conducive to data exchange, resource sharing, print sharing; at the same time access to the Internet, increase the internal resource information. This paper mainly expounds the current enterprise network planning and design, through the establishment of a medium-sized enterprise network to give you a better understanding of the principle of the enterprise network, the main contents are: the user demand analysis, network design principle, selection of network equipment, network planning and network topology, structure design, security design, IP address planning, routing protocol selection, wireless LAN and VoIP deployment, the implementation of the program. The entire enterprise network simulation in the Cisco Packet Tracer, and tested to achieve the desired effect.
Key words: Enterprise network; network design principle; IP address planning;network structure design;Packet Tracer;VPN II
