中文摘要
現(xiàn)代企業(yè)的競爭是十分激烈的，為了企業(yè)的生存和發(fā)展，企業(yè)必須適應(yīng)客戶需求和經(jīng)營環(huán)境變化。企業(yè)需要采用先進(jìn)的信息技術(shù)，加強(qiáng)企業(yè)通信和協(xié)同工作的機(jī)制，一個(gè)有效的途徑就是建立企業(yè)的Intranet，他對企業(yè)的作用主要反映在：提高經(jīng)營效率，節(jié)省時(shí)間和開銷；允許獲得及時(shí)的信息；改進(jìn)通信環(huán)境；改善協(xié)同工作的機(jī)制；開發(fā)企業(yè)員工的創(chuàng)造力和革新精神。
在組建企業(yè)網(wǎng)的時(shí)候，由于企業(yè)經(jīng)營、辦公的范圍較廣，所以組建企業(yè)網(wǎng)還是耗費(fèi)了一定的資金、人力資源。對于人力、物力、財(cái)力較弱的中小型企業(yè)而言，組建企業(yè)網(wǎng)的困難較多。比如，企業(yè)本身缺乏上網(wǎng)技術(shù)，開發(fā)人員和維護(hù)人員缺乏，組建企業(yè)網(wǎng)投入的資金較少，原有設(shè)施不夠完善；二是擔(dān)心組網(wǎng)及上網(wǎng)后的價(jià)格太貴，企業(yè)難以承受等等。但是，從另一方面來看，中小型企業(yè)又有它的優(yōu)勢：它的辦公范圍較小，部門分布緊湊，組建企業(yè)網(wǎng)時(shí)少了地理位置的限制，還可節(jié)省線材之類設(shè)備的消耗，其軟件系統(tǒng)也不必太復(fù)雜。
　　建設(shè)企業(yè)網(wǎng)網(wǎng)絡(luò)不是一件容易的事情,圍繞著網(wǎng)絡(luò)設(shè)計(jì)所要解決的問題、網(wǎng)絡(luò)設(shè)計(jì)的內(nèi)容、網(wǎng)絡(luò)的特點(diǎn)、網(wǎng)絡(luò)的實(shí)現(xiàn)進(jìn)行了闡釋。對設(shè)計(jì)要求需求分析；選定網(wǎng)絡(luò)的類型及拓?fù)浣Y(jié)構(gòu)；網(wǎng)絡(luò)所需要的配置（主機(jī)、物理設(shè)備、交換機(jī)、路由器）的選型，進(jìn)行各種服務(wù)器、交換機(jī)Vlan和路由器的配置；對完成網(wǎng)絡(luò)提供服務(wù)軟件的選型及配置。還有對于網(wǎng)絡(luò)安全性進(jìn)行分析，設(shè)置防火墻、防病毒系統(tǒng)，以及備份系統(tǒng)等。

Abstract

The modern enterprise's competition is extremely intense, for enterprise's survival and the development, the enterprise must adapt the customer demand and the management environmental variation. The enterprise needs to use the advanced information technology, strengthens the enterprise correspondence harmonious cooperation with the work mechanism, an effective way is establishes the enterprise Intranet, he to enterprise's function main reflection in: Enhances the management efficiency, saves the time and the expenses; The permission obtains the prompt information; Improvement correspondence environment; Improvement joint operation mechanism; Development enterprise staff's creativity and innovation spirit. Is setting up the enterprise network time, because the enterprise manages, the work scope is broader, therefore set up the enterprise network or to consume the certain fund, the human resources. Regarding the manpower, the physical resource, a financial resource weaker small and medium-sized enterprise say, sets up the enterprise network the difficulty to be more. For instance, enterprise itself deficiently accesses the net the technology, the development personnel and the attendant lacks, sets up the fund which the enterprise network invests to be less, original facility insufficient consummation; Two, worried the network and accesses the net the after price too to be expensive, the enterprise withstands with difficulty and so on. But, on the other hand, the small and medium-sized enterprise also has its superiority: Its work scope smaller, the department distributes compact, sets up when the enterprise network has been short the geographical position limit, but also may save the line material and so on equipment the consumption, its software system also does not need too to be complex. The construction enterprise network network is not an easy matter, revolved the question, the network design content, the network characteristic, the network realization which the network design had to solve to carry on the explanation. To design request demand analysis; Designates the network the type and the topology; The network needs disposition (main engine, physical equipment, switchboard, router) the shaping, carries on each kind of server, switchboard Vlan and the router disposition; To completes the network to provide service software the shaping and the disposition. Also has regarding the network security carries on the analysis, establishes the firewall, the anti-virus system, as well as backup system and so on.
