【正文】 重慶郵電大學(xué)移通學(xué)院 通 信工程 本科畢業(yè)設(shè)計(jì) (論文 ) I 無(wú)線局域網(wǎng)的分析與設(shè)計(jì) 摘 要 隨著大學(xué)校 園 網(wǎng)絡(luò)數(shù)據(jù)傳輸需要的逐漸增加，特別是應(yīng)用數(shù)據(jù)、話音、視像多媒體的傳輸量的增加 ， 校園網(wǎng)建設(shè)正向數(shù)字化、智能化方向發(fā)展。而校園無(wú)線局域網(wǎng)作為校園網(wǎng)的重要組成部分，因此在校園網(wǎng)中建設(shè)無(wú)線局域網(wǎng)作為有線校園局域網(wǎng)的重要補(bǔ)充顯得尤為重要。 無(wú)線局域網(wǎng)是相當(dāng)便利的數(shù)據(jù)傳輸系統(tǒng)，它利用射頻技術(shù)，取代舊式的雙絞銅線所構(gòu)成的局域網(wǎng)絡(luò)，使得用戶能夠利用其簡(jiǎn)單的存取架構(gòu)，信息隨身化、隨時(shí)隨地連接網(wǎng)絡(luò)世界。 無(wú)線局域網(wǎng)彌補(bǔ)有線局域網(wǎng)絡(luò)之不足，以達(dá)到網(wǎng)絡(luò)延伸之目的。高校校園網(wǎng)的網(wǎng)絡(luò)建設(shè)與網(wǎng)絡(luò)技術(shù)發(fā)展幾乎是同步進(jìn)行的。高校不僅承擔(dān)著教書育人的工作，更承擔(dān)著部分國(guó)家級(jí)的科研任務(wù)。同時(shí)考慮未來(lái)幾年網(wǎng)絡(luò)平臺(tái)的發(fā)展趨勢(shì) , 為了充分滿足高校骨干網(wǎng)對(duì)高速、智能、安全、認(rèn)證計(jì)費(fèi)等的需求，可以利用萬(wàn)兆以太網(wǎng)的校園網(wǎng)組網(wǎng)技術(shù)。構(gòu)建校園網(wǎng)骨干網(wǎng)，實(shí)現(xiàn)各個(gè)分校區(qū)和本部之間的連接，以 及實(shí)現(xiàn)端到端的以太網(wǎng)訪問(wèn)，提高了傳輸?shù)男?，有效地保證了遠(yuǎn)程多媒體教學(xué)、數(shù)字圖書館等業(yè)務(wù)的開展。 本文通過(guò)分析網(wǎng)絡(luò)技術(shù)特點(diǎn)和目前校園網(wǎng)的普遍需求及實(shí)際應(yīng)用，講解了校園網(wǎng)絡(luò)的基本知識(shí)，包括路由器、三層交換機(jī)、無(wú)線 AP、服務(wù)器等網(wǎng)絡(luò)設(shè)備， VLAN和 IP 地址，同時(shí)對(duì)主要設(shè)備進(jìn)行了選型。 【關(guān)鍵詞】無(wú)線局域網(wǎng) 校園網(wǎng) 網(wǎng)絡(luò)設(shè)備 服務(wù)器 網(wǎng)絡(luò)安全 重慶郵電大學(xué)移通學(xué)院本科畢業(yè)設(shè)計(jì) (論文 ) II ABSTRACT With the gradual increase need of campus’work data transmission,especially the increase of application data,voice,video and multimedia transmission capacity,the campus work construction is going in the direction of digitization and campus wireless LAN,however, is an essential part of campus work, therefore,it plays an important role as a significant supplement of wired campus LAN. Wireless LAN is very convenient data transmission system,which uses radio frequency technology to replace the old copper twistedpair posed by local area work,allowing users to access its simple structure,information technology players, connect to the work anywhere in the world. Wireless local area work LAN cables to make up deficiencies,and to achieve the purpose of extending the work of works and work technology development carried out almost simultaneously,Universities not only bear the work of teaching,but also bear some of statelevel research tasks,taking into consideration the next few years,the development trend of work platform, in order to fully meet the colleges and universities for highspeed backbone work,intelligence,security,authentication and accounting needs,etc.,we can use the campus work Gigabit Ether working of the campus backbone work, the realization of the various campus areas and the connections between the headquarters, as well as endtoend Ether access and improve the efficiency of the transmission,effectively ensure the longrange multimedia teaching, digital libraries and other operations. This text passes and analyses work technology characteristic and the general demand for campus work at present and practical application,it has explained the basic knowledge of the campus work,including the router,third layer of work switch,wireless AP,puter Server work equipment,VLAN,and IP address,having carried on the selecting type to the capital equipment at the same time. 【 Key words】 Wireless LAN Campus work work equipment server work 重慶郵電大學(xué)移通學(xué)院本科畢業(yè)設(shè)計(jì) (論文 ) III security 重慶郵電大學(xué)移通學(xué)院本科畢業(yè)設(shè)計(jì) (論文 ) IV 目 錄 前 言 ................................................................................................................................... 1 第一章 無(wú)線局域網(wǎng)（ WLAN）的概述 ........................................................................... 2 第一節(jié) 無(wú)線局域網(wǎng)的簡(jiǎn)述及發(fā)展史 ....................................................................... 2 一、無(wú)線局域網(wǎng)的基本概念 ............................................................................... 2 二、無(wú)線局域網(wǎng)的背景及發(fā)展?fàn)顩r ................................................................... 2 三、無(wú)線局域網(wǎng)的發(fā)展史 ................................................................................... 2 四、研究的意義 ................................................................................................... 3 第二節(jié) 無(wú)線局域網(wǎng)的特點(diǎn) ....................................................................................... 3 一、無(wú)線局域網(wǎng)的優(yōu)點(diǎn) ....................................................................................... 3 二、無(wú)線局域網(wǎng)的局限性 ................................................................................... 4 第三節(jié) 無(wú)線局域網(wǎng)的技術(shù)標(biāo)準(zhǔn) ............................................................................... 5 一、主要的 協(xié)議標(biāo)準(zhǔn) .............................................................................. 6 二、藍(lán)牙（ Bluetooth）標(biāo)準(zhǔn) ............................................................................... 6 三、 HomeRF（家庭網(wǎng)絡(luò)）標(biāo)準(zhǔn) ........................................................................ 6 四、各協(xié)議之間的區(qū)別 ....................................................................................... 7 第二章 校園無(wú)線局域網(wǎng) (WLAN)的設(shè)計(jì) ......................................................................... 8 第一節(jié) 校園網(wǎng)的需求分析 ....................................................................................... 8 一、建設(shè)背景 ....................................................................................................... 8 二、 WLAN 由以下幾個(gè)部分組成 ...................................................................... 8 三、總體建設(shè)目標(biāo) ............................................................................................... 8 第二節(jié) 組網(wǎng)方案的分析 ........................................................................................... 9 一、組網(wǎng)原則 ....................................................................................................... 9 二、拓?fù)浣Y(jié)構(gòu) ....................................................................................................... 9 第三節(jié) 主要設(shè)備的選擇原則 ................................................................................. 11 一、路由器的關(guān)鍵技術(shù)指標(biāo) ............................................................................. 12 二、交換機(jī)的主要技術(shù)指標(biāo) ............................................................................. 13 重慶郵電大學(xué)移通學(xué)院本科畢業(yè)設(shè)計(jì) (論文 ) V 三、服務(wù)器的選型原則 ..................................................................................... 13 四、光纖收發(fā)機(jī)器 ............................................................................................. 14 第四節(jié) 路由協(xié)議 .....................................................................................................
