摘要
 
 當(dāng)今社會(huì)是一個(gè)以網(wǎng)絡(luò)為平臺(tái)的信息時(shí)代，企業(yè)信息化已經(jīng)成為現(xiàn)在企業(yè)的重要財(cái)富和資源。而隨著企業(yè)對(duì)未來網(wǎng)絡(luò)技術(shù)和應(yīng)用環(huán)境要求的不斷提高，如何建設(shè)一個(gè)安全，穩(wěn)定，快速的企業(yè)網(wǎng)絡(luò)來保障日常的工作需求變的十分迫切。一個(gè)現(xiàn)代化的企業(yè)網(wǎng)建設(shè)是一個(gè)想更深遠(yuǎn)發(fā)展的企業(yè)所必須的。在全球信息化的滾滾浪潮中,只有走在信息化的前頭，你的企業(yè)才能更加有利地發(fā)展，才能更加的穩(wěn)固與前進(jìn)。
 本論文研究的是一個(gè)大型公司的網(wǎng)絡(luò)改造方案，案例為總部四棟大樓的拓?fù)涓脑欤�所使用的設(shè)備包括防火墻，VPN設(shè)備，和三層交換機(jī)，涉及的技術(shù)包括OSPF協(xié)議，DHCP源防護(hù)，VLAN間路由和VRRP及MSTP等。在解決該公司的安全問題時(shí)，提出了自己的一些意見及應(yīng)對(duì)措施。在所運(yùn)用技術(shù)和合理的拓?fù)湟?guī)劃下的企業(yè)網(wǎng)絡(luò)將使其業(yè)務(wù)效率得到最大的提高。

ABSTRACT
 
 Today's society is a information age which are based on the network platform, the information technology has become an important asset and resource of enterprises.With the high requirements of the application environment and the new network technology use in the company in the future ,how to construct a safe ,stable and rapid enterprise network become more and more impendent.It is a good way to protect the daily work requirements.Construction of a modern enterprise network is a far-reaching developmental company’s requires.In the rolling tide of global information age,only to go ahead in information technology,the company’s business can be more favorable to develop and to get more markets in the world.
 This topic of my thesis is a large company’s network design and apply program,the case for the headquarters of the topological transformation including four buildings.The network devices use in the program are consist of multilayer swithes,routers and firewall&VPN device.The technology use in the program are including OSPF protocol,DHCP source protection,internal VLAN routing and virtual router redundancy protocol. In the company's security problem,I put forward my own views .In the use of technology and a reasonable network topology planning will make the company largest increase of operation efficiency .
