中 文 摘 要

计算机网络自从20世纪60年代未诞生以来，仅在几十年间的时间里，即以异常迅猛的速度发展起来，被越来越广泛地应用于政治、经济、军事、生产及科学技术的各个领域。在当今社会及未来，谁更快获得信息资源，谁就能更有效的使用信息资源，谁就能在各种竞争上占据主导地位，随着计算机网络的发展和宽带接入的普及，各种网络应用将层出不穷，计算机在社会各个领域的应用和影响也早已渗透到了人们工作和生活的各个方面。目前在中国国民经济和社会发展中一直占据至关重要的战略地位的中小型企业，由于对网络技术的不了解，通常厂商一般都会采用价格最贵化、设备最好化、高度冗余化去做项目的设计，整体的方案将以追求利润为目的，设计的方案经常出现大量设备闲置，而企业出于需求与成本控制等各种因素的综合考虑，希望方案能满足需求的同时控制成本，同时尽量做到冗余且提供投资保护，方便后续的需求扩展，厂商提供的方案与企业的需求就此产生了矛盾，如何设计一个性价比更高、更适合于中小型企业的网络方案是势在必行的课题，此方案的设计使所有的中小型企业在当今及未来的网络建设有着得要的指导及参考意义，也是本次毕业设计方案的主要目的与价值。本文通过东莞某企业的具体案例来说明中小型企业资金能力及对企业网络的需求进行分析，设计适用于中小型企业的组网方案。组建一个基本能覆盖整个企业园区、广域网接入、远程访问、数据服务器群等范围的互联网络，将企业内各种计算机、服务器、终端设备连接起来，并通过一定接口连接到广域网。

Abstract

Since the 20th century, computer networks, not since the birth of 60 years, only a few years time, that is extraordinarily rapid pace up, were more widely used in political, economic, military, manufacturing and various fields of science and technology . In today's society and the future, who is faster access to information resources, who will be able to more effectively use information resources, who will be able to dominate all competition, with the development of computer networks and the popularity of broadband access, various the emerging network applications, computer applications in all areas of society and the impact has already penetrated into the people in all aspects of work and life. Current economic and social development in China has been crucial to the strategic position occupied small and medium enterprises, because of the lack of understanding of network technology, vendors are usually the most expensive of the generally used, the device is best, highly redundant technology to to do the project design, the overall profit will be for the purpose of the program, often a large number of programs designed equipment idle, and the corporate demand and cost control for a variety of factors into account, hope the plan to satisfy the demand while controlling costs, redundant as far as possible while providing investment protection and facilitate the expansion of the follow-up demand, vendors and business needs of this program had a conflict, how to design a cost-effective, more suitable for small and medium enterprises is inevitable network solution is the subject line, this program is designed to provide small and medium enterprises of all current and future network construction has got to the guidance and reference value, is also the graduate design program's main purpose and value. In this paper the specific case of a company in Dongguan to illustrate the financial capacity of small and medium enterprises and the needs of the enterprise network analysis, design for small and medium enterprise networking solutions. Essential to the formation of a campus-wide enterprise, wide area network access, remote access, data, server farms and other Internet-wide, enterprise of all kinds of computers, servers, terminal equipment and, through a certain interface to connect to WAN.

绪论

随着Internet在全球的发展与普及，企业网络技术的发展以及企业生存和发展需要促成了企业网的形成。自20世纪90年代以来，企业网络已经成为连接企业、事业单位各部门与外界交流信息的重要基础设施。基于局域网和广域网技术发展起来的企业网络技术得到迅速的发展。

为了适应网络经济的飞速发展，扩大企业经营的规模和范围，方便企业内部和企业之间的交流，节省办公开销，提高企业的管理水平，企业发展Intranet（企业内部网）已经是刻不容缓。

另外，我国中小型数量已经超过2000万家以上，在国民经济中，60%的总产来自于中小企业，并为社会提供了60%以上的就业机会。然而，在中国国民经济和社会发展中一直占据着至关重要的战略地位的小中企业，其信息化程度却比较落后。今后如何应对瞬息万变、竞争激烈的国内外市场环境以及如何利用网络技术迅速提升企业核心竞争力就是成为企业成败的关键所在。

从企业对信息的需求来看

面对着激烈的市场竞争，公司对信息的收集、传输、加工、存储、查询、预测、决策及即时的交流、沟通等工作量越来越大，原来的电脑出于网络技术或是安全性等因素考虑，一直只是停留在单机工作的模式，各部门及科室间的数据不能实现共享，致使工作效率大大下降，纯粹手 …… 此处隐藏：10214字，全部文档内容请下载后查看。喜欢就下载吧 ……
