大型企业网络规划与设计
摘 要
迅速发展的Internet正在对全世界的信息产业带来巨大的变革和深远的影响。市场的全球化竞争已成为趋势。对于大型企业来说，在调整发展战略时，必须考虑到市场的全球竞争战略，而这一切也将以信息化平台为基础，借助计算机网络原理及网络规划技术，以网络通畅为保证。
企业内部网（Intranet）是国际互连网（Internet）技术在企业内部或封闭的用户群内的应用。Intranet是使用Internet技术,特别是TCP/IP协议而建成的企业内部网络。这种技术允许不同计算机平台进行互通,且不用考虑其位置。也就是所说的用户可以对任何一台进行访问或从任何一台计算机进行访问。
本文从企业网络需求开始分析，根据现阶段cisco公司主流网络设备进行选材,规划最适用于目标网络的拓扑结构,建设合理的网络设计方案。本课题实施部分由GNS3模拟器来搭建网络拓扑结构，利用cisco设备操作系统unzip-c2691-advsecurityk9-mz.124-11.T2作为拓扑内所有设备核心IOS，然后用SecureCRT进行路由器交换机的相关配置，并测试其结果最终验证网络的规划与设计符合大型企业的需求。

Large Enterprise Network Planning and Design
Abstract
The rapid development of the Internet is all over the world information industry of enormous change and far-reaching consequences. Market competition has become the trend of globalization. For large enterprises, in adjusting the development strategy, must take into account the market's global competitiveness strategy, and all this information platform will also be based on the principle of the use of computer networks and network planning technology to the network in order to ensure patency.
Intranet is an international Internet technology in the enterprise or within a closed user group applications. Intranet is the use of Internet technologies, especially TCP / IP protocol and the completion of the enterprise internal network. This technology allows interoperability of different computer platforms, and do not have to consider its position. That is what the user can visit any or from any computer access.
From the start the whole enterprise class network needs analysis, based on the mainstream stage cisco network equipment company selection, with the goal to build the most suitable network topology, designed with network technology. As part of this implementation to build the simulator GNS3 network topology, the use of cisco device operating systems unzip-c2691-advsecurityk9-mz.124-11.T2 for all equipment within the core topology IOS, routers and switches using SecureCRT for the configuration, and view the experimental results to verify that the network meets business needs.
Keywords：Enterprise networks, Topology, Redundancy, Routing, Switching
