摘 要市场的全球化竞争已成为趋势。对于中小企业来说，在调整发展战略时，必须考虑到市场的全球竞争战略，而这一切将以信息化平台为基础，以网络通畅为保证。通过建立各种虚拟专网（VPN）和企业外部网络（Extranet），建立企业全球信息网络是未来企业网络应对市场全球竞争的一种策略。 本论文以某企业新建厂房的局域网规划和设计为背景，借助计算机网络原理及网络规划技术，从企业局域网的概念及相关计算机网络技术入手，比较详细地设计出了该企业网建设的实施方案及建设规划,以期达到先进、安全、实用、可靠的目标. 论文对该企业的组网需求进行了分析，比较各种组网技术，从实用角度论述了局域网主干网选择，综合布线，各种设备选择，网络安全，网络管理等方面。文中参照了当前诸多企业局域网和校园网络方面的相关组网形式和成熟的网络技术，该方案基本达到了预期的目标.关键词：交换机、路由器、千兆以太网、网络安全、拓扑结构、拓扑图。 AbstractThe market globalization competition has become the tendency. Regarding the small and medium-sized enterprise, when the adjustment developmental strategy, must consider the market the global competition strategy, but all these take the informationization platform as a foundation, take the network unobstructed as the guarantee. Through establishes each kind of hypothesized special net (VPN) and enterprise exterior network (Extranet), will establish the enterprise whole world information network is the future enterprise network should to the market global competition one kind of strategy. The present paper take some enterprise newly built workshop local area network plan and the design as a background, with the aid of the computer network principle and the network planning technology, from the enterprise local area network concept and correlation computer network technology obtaining, compared with in detail designed the implementation plan and the construction plan which this enterprise network constructed,Achieves advanced, safe, practical, the reliable goal by the time. The paper has carried on the analysis to this enterprise's network demand, compared with each kind of network technology, elaborated the local area network backbone network choice from the practical angle, comprehensive wiring, each kind of equipment choice, network security, aspects and so on network management. In the article has referred to the current many enterprise local area network and the campus network aspect related network form and the mature networking, this plan has achieved the anticipated goal basically.Key word: Switchboard, Router, Milliardfold ethernet, Network security, Topology architecture, Topology graph. 目 录前 言 ······································· ·······················6第一章 中小企业网络建设现状及未来··································································71.1 我国中小企业网络建设现状分析····························································7 1.1.1 面临的挑战························································································7 1.1.2 寻求进一步发展··············································································7 1.2 我国中小企业网络应用核心电子商务······································8第二章 需求分析·····································································································112.1 项目简述···································································································112.2 总体建设目标···························································································112.3 设计原则、目标以及详细方案简介·······················································112.3.1. 设计原则·························································································122.3.2 网络系统建议方案·········································································12第三章 交换与路由·································································································143.1 交换和路由的概念···················································································143.1.1 网络层次结构·················································································143.1.2 交换·································································································153.1.3 路由·································································································163.1.4 全交换园区网络·············································································173.2 第三层交换·······························································································183.2.1 什么是三层交换·············································································183.2.2 三层交换原理·················································································183.2.3 三层交换机种类·············································································183.3 交换机Catalyst 3550············································································203.3.1 主干或机架堆叠顶层的高性能路由 ···········································203.3.2 增强的服务质量·············································································213.3.3 完善的流量管理·············································································223.3.4 Cisco集群管理套件（CMS）························································223.4 网络的核心Cisco Catalyst 4006························································233.4.1 具有服务质量和成熟流量管理功能的智能化网络服务·············243.4.2 增强的性能和可扩展性················
