随着信息技术的快速发展，园区对信息的依赖性越来越明显，建立一个快速，稳定的网络平台，对园区运行的效率和执行力都有很大的搞高。同时，一个好的信息网络平台，可以更准确快速的帮助园区决策者们制定出符合园区发展的方针和政策。园区内部网（Internet）是国际互联网（Internet）技术在园区内部或封闭的用户群内的应用。Internet是使用Internet技术，特别是TCP/IP协议而建成的企业内部网络。这种技术允许不用计算机平台进行互通，暂不用考虑其位置。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。
本毕业设计解决方案的设计目的是为园区用户提供组建园区网参考而设计的。包含了在架设园区级园区网中所必需要考虑和解决的问题，如对网络层次的设计，园区对网络的发展要求，网络的基础架构，网络操作平台的设计，园区信息安全和对外发布的设计，实施过程中必需检查的细节等影响网络正常运行因素。同时也考虑服务提供商在为园区建立园区网后，应保证的义务和责任。
本文从园区网络需求开始分析，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 设备操作用 c3640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园区的需求。

With the rapid development of information technology, the dependence of campus on information becomes more and more obvious. The establishment of a fast and stable network platform will greatly improve the efficiency and execution of the operation of the park.At the same time, a good information network platform can more accurately and quickly help the park decision-makers to formulate policies and policies in line with the development of the park.Campus Intranet (Internet) is the application of Internet) technology within the campus or in a closed user group. Internet is an enterprise intranet built using Internet technology, especially the TCP/IP protocol. Luo.This technology allows for interworking without the use of computer platforms, and does not need to be considered for the time being.That is, the user can access any one or from any computer.
The design of the graduation solution is designed to provide reference for campus users.Including the problems that must be considered and solved in setting up the campus campus network, such as the design of the network level, the requirements of the campus for the development of the network, the basic structure of the network, the design of the network operation platform,The design of campus information security and external release, the details that must be checked in the process of implementation, and other factors affecting the normal operation of the network.Also consider the obligations and responsibilities of service providers in establishing campus networks for the campus.
This paper begins with the analysis of campus network requirements, selects materials according to the current mainstream network equipment of cisco Company, plans the topology structure that is most suitable for the target network, and builds a reasonable network design scheme.The implementation of this project is implemented by GNS3 simulator to build the network topology, using C3640 as the core of all devices in the topology using cisco device operation, and then using SecureCRT to configure the router switch.Finally, the test results verify that the network planning and design meet the requirements of the park.
