小型校園網(wǎng)構(gòu)建計算機網(wǎng)絡(luò)zq

1、企業(yè)網(wǎng)絡(luò)設(shè)計1. 課程設(shè)計目的1、增加對計算機網(wǎng)絡(luò)軟、硬件組成的感性認(rèn)識初步學(xué)會典型局域網(wǎng)絡(luò)的操作、 使用技能；2、加深理解網(wǎng)絡(luò)分層結(jié)構(gòu)概念尤其是對會話層、表示層、應(yīng)用層等高層協(xié)議軟件的通信功能、實現(xiàn)方法，掌握網(wǎng)絡(luò)互連設(shè)備的使用及工作原理，掌握IP地址的配置；3、初步掌握局域網(wǎng)的設(shè)計技術(shù)和技巧培養(yǎng)開發(fā)網(wǎng)絡(luò)應(yīng)用的獨立工作能力。2. 設(shè)計方案論證2.1設(shè)計思路總體設(shè)計思路進行企業(yè)網(wǎng)絡(luò)總體設(shè)計，首先，進行對象研究和需求調(diào)查，弄清企業(yè)的性質(zhì)、 任務(wù)和特點，對企業(yè)的信息化環(huán)境進行準(zhǔn)確的描述，明確系統(tǒng)建設(shè)的需求和條件； 其次，在應(yīng)用需求分析的基礎(chǔ)上，確定企業(yè) In tra net服務(wù)類型，進而確定系統(tǒng)建設(shè)

2、 的具體目標(biāo)，包括網(wǎng)絡(luò)設(shè)施、站點設(shè)置、開發(fā)應(yīng)用和管理等方面的目標(biāo)；第三，確 定網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)和功能，根據(jù)應(yīng)用需求、建設(shè)目標(biāo)和學(xué)校主要建筑分布特點，進行 系統(tǒng)分析和設(shè)計；第四，確定技術(shù)設(shè)計的原則要求，如在技術(shù)選型、布線設(shè)計、設(shè) 備選擇、軟件配置等方面的標(biāo)準(zhǔn)和要求；第五，規(guī)劃安排企業(yè)網(wǎng)建設(shè)的實施步驟。2.1.2 網(wǎng)絡(luò)設(shè)計將網(wǎng)絡(luò)中心設(shè)在D座樓，支持遠程教學(xué)，可以接入互聯(lián)網(wǎng)，具有廣域網(wǎng)訪問的 安全機制和網(wǎng)絡(luò)管理功能。以 D座樓為中心，用光纖連接到其它建筑物，構(gòu)成校園 網(wǎng)光纖主干。網(wǎng)絡(luò)結(jié)構(gòu)分成三層：核心層、匯聚層、接入層。（1）終端用戶包括：A座樓有48個校園網(wǎng)普通用戶；B座樓有1個包含24個多媒體用戶的

3、電子閱覽室；C座樓有1個包含48個用戶的多媒體教室（性能要求高于電子閱覽室）。D座樓是網(wǎng)絡(luò)中心。（2）支持遠程教學(xué)，可以接入互聯(lián)網(wǎng)，具有廣域網(wǎng)訪問的安全機制和網(wǎng)絡(luò)管理功能。（3）各樓之間的距離為500米。由于各座樓之間的距離是 500米，而雙絞線的最遠距離是100米，所以基于對 條件要求的考慮，我們需要選擇光纖或串行線作為傳輸介質(zhì)。考慮傳輸高速率和擴 展的需求，企業(yè)網(wǎng)樓與樓之間采用光纖傳輸。網(wǎng)絡(luò)主干采用多模光纖。網(wǎng)絡(luò)中心到 主建筑物結(jié)點采用多模光纖連接。布線采用星形拓?fù)浣Y(jié)構(gòu)，這樣當(dāng)過渡到ATM時，不需要重新布線可使整個網(wǎng)絡(luò)保持原有的拓?fù)浣Y(jié)構(gòu)。以上特點分層網(wǎng)絡(luò)結(jié)構(gòu)可以獲 得良好的擴展性，根據(jù)實際

4、需求，整個企業(yè)網(wǎng)采用星型結(jié)構(gòu)，由D座樓出發(fā)，延伸到ABC座樓。再從各個樓出發(fā)，以同軸電纜作為傳輸介質(zhì)。由云到D座樓為A類網(wǎng)，由D座樓到各個樓之間為B類網(wǎng)，各個內(nèi)部為C類網(wǎng)。對于整個網(wǎng)絡(luò)的拓?fù)浣Y(jié)構(gòu)為混合型結(jié)構(gòu)，以路由器為網(wǎng)絡(luò)中心的星型結(jié)構(gòu)，各 部門以交換機為主結(jié)點的樹型結(jié)構(gòu)。由于計算機與網(wǎng)絡(luò)技術(shù)的特殊性，網(wǎng)絡(luò)建設(shè)需要考慮以下一些因素：系統(tǒng)的先 進性、體統(tǒng)的穩(wěn)定性、系統(tǒng)的可擴展性、系統(tǒng)的可維護性、應(yīng)用系統(tǒng)和網(wǎng)絡(luò)系統(tǒng)的 配合度、與外界網(wǎng)絡(luò)的連通性、建設(shè)成本的可接受度等。具體設(shè)計表1校園網(wǎng)設(shè)備選擇表樓座設(shè)備型號數(shù)量A座樓RouterRouter-PT1Switch2960-242PCPC-PT4B座樓
