摘 要
随着全球性的国际计算机互联网Internet的迅速发展与普及，整个信息产业的面貌发生了巨大的改变，因而使得信息技术产业从以计算机为中心发展到以网络为中心,可见网络在当今社会的功能不容小视。网络给社会带来的是革命性变化，也正因为网络所带来的这些改变，使得各行各业的对各自网络建设的必要性尤为突出。本文以乔森公司的网络规划方案为例，提出了一种中小型企业的网络设计方案，通个这个方案的设计来完成中小企业的网络建设，实现网络功能的需求，也更方便公司的集中式管理。乔森公司作为一个发展势头猛烈的公司，为了满足未来发展的需求，与客户有一个更好的交流平台，更好地面向客户，迫切需要构建一个公司网络。
本文主要介绍乔森公司的网络规划方案。由于公司业务发展的不断扩大，员工不断增多，传统的公司管理方式、通信方式以及信息交流平台都已无法满足公司发展的需求，所以对公司的网络建设是客不容缓的。本文模拟一个中小型企业的网络设计项目，分析网络需求，结合乔森公司的具体部署，利用路由交换技术以及广域网技术，设计了一套网络解决方案，充分发挥网络的功能。

Abstract
With a development and popularization of Internet information industry, the industry about information have a great change, and it makes the information technology industry development center by computer is from the center to network, network in nowdays the function are benchmark. Network brings to the society is the revolutionary change, but also because of these changes brought by Internet, people from all walks of life to each network construction necessity outstandingly. Based on the network planning scheme of Johnson as an example, this paper puts forward a kind of small and medium-sized enterprise network design, the design scheme of small and medium-sized enterprises to complete the network construction and network function requirement, also more convenient centralized management company. Johnson company as a momentum of development of the company, in order to meet the heavy demand, and the future development of customers have a better communication platform, the better for customers, the urgent need to build a corporate network.
This paper mainly introduces the network planning scheme Johnson company. Because of the company business development expands unceasingly, the staff of the company is on the increase, traditional management mode and means of communication and information exchange platform already cannot satisfy the needs of the development of the company, so the network construction of company is urgent. Let guest This is a small and medium-sized enterprise network simulation design project, analysis, combined with the requirements of the specific deployment, Johnson company by routing exchange technology and wan technologies, design a set of solutions, give full play to the function of network.
