园区网络规划与设计
摘 要
随着现代科学技术和互联网的迅猛发展，以计算机和通讯技术为基础的管理系统正处于高速发展的时期。同时，伴随着经济文化水平的显著提高，人们对生活质量的要求也在不断提升，对工作的环境以及要求也日益提高。在一个园区内进行办公的人们之间需要相互的通信，同时在相互通信的过程中又能确保信息通畅与保密，于是对此园区的一个网络规划与设计应运而生。
本课题简要地讨论了企业网络规划设计中涉及到的网络技术、规划设计方法、网络性能以应用分析等问题，为企业网络的规划、设计和升级改造等方面在技术及应用上提供参考，以使在建或规划中的校园网络具备较高的整体性能。通过对园区网络的分析，从性能和价值上满足园区网络的需求，然后对企业园区网络进行划分vlan、设置管理域等配置，不断的优化企业的网络，从而达到企业安全、快速访问网络资源的目的。
通篇分为6个章节进行讨论，从技术概念、需求分析、系统实现等篇章对网络进行系统化的设计与规划，主要讨论园区局域网络建设过程中可能用到的各种技术、实施方案为设计准则，为广大师生在今后建设园区网的过程中提供一些建议和准则。
关键词：园区网络，规划与设计，网络建设

Planning and Design of Campus Network
Abstract
With the rapid development of modern science technology and Internet, based on computer and communications technology management system is in a high-speed development period. At the same time, along with the economic and cultural level has increased dramatically, people’s life quality requirements are also rising, working environment and requirement also increasing day by day. In a park within the office need to mutual communication between people, and in the process of communicating with each other must ensure the information flow and secrecy, so a network planning and design of this park came into being
This topic briefly discussed related to networking technologies in the enterprise network planning and design, planning and design methods, network performance, and applying analytical and other issues, provide a reference for the enterprise planning, design and upgrading in the technology and applications layer. So under construction or in the planning campus network with higher overall performance. Through campus network analysis, performance and value to meet the needs of the campus network, and then divide enterprise campus network with VLAN, set management domain configuration, optimize the network, so as to achieve security, fast access to network resources purposes.
Throughout is divided into six chapters to discuss, from a technical concept, requirements analysis, system implementation, etc. to systematic design and planning of network, mainly discuss the campus local area network construction process may be used various technique and implementation plan for design principles, for the majority of teachers and students in the process of the construction of campus network in the future to provide some Suggestions and principles.
Key words：campus network，planning and design，network construction
