小型校園網的構建計算機網絡zq

1、企業(yè)網絡設計1. 課程設計目的1、增加對計算機網絡軟、硬件組成的感性認識初步學會典型局域網絡的操作、 使用技能；2、加深理解網絡分層結構概念尤其是對會話層、表示層、應用層等高層協議軟件的通信功能、實現方法，掌握網絡互連設備的使用及工作原理，掌握IP地址的配置；3、初步掌握局域網的設計技術和技巧培養(yǎng)開發(fā)網絡應用的獨立工作能力。2. 設計方案論證2.1設計思路2.1.1總體設計思路進行企業(yè)網絡總體設計，首先，進行對象研究和需求調查，弄清企業(yè)的性質、 任務和特點，對企業(yè)的信息化環(huán)境進行準確的描述，明確系統建設的需求和條件； 其次，在應用需求分析的基礎上，確定企業(yè) In tra net服務類型，進而確

2、定系統建設 的具體目標，包括網絡設施、站點設置、開發(fā)應用和管理等方面的目標；第三，確 定網絡拓撲結構和功能，根據應用需求、建設目標和學校主要建筑分布特點，進行 系統分析和設計；第四，確定技術設計的原則要求，如在技術選型、布線設計、設 備選擇、軟件配置等方面的標準和要求；第五，規(guī)劃安排企業(yè)網建設的實施步驟。2.1.2 網絡設計將網絡中心設在D座樓，支持遠程教學，可以接入互聯網，具有廣域網訪問的 安全機制和網絡管理功能。以 D座樓為中心，用光纖連接到其它建筑物，構成校園 網光纖主干。網絡結構分成三層：核心層、匯聚層、接入層。（1）終端用戶包括：A座樓有48個校園網普通用戶；B座樓有1個包含24個多

3、媒體用戶的電子閱覽室；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座樓是網絡中心(2) 支持遠程教學，可以接入互聯網，具有廣域網訪問的安全機制和網絡管理功能。(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。考慮傳輸高速率和擴 展的需求，企業(yè)網樓與樓之間采用光纖傳輸。網絡主干采用多模光纖。網絡中心到 主建筑物結點采用多模光纖連接。布線采用星形拓撲結構，這樣當過渡到ATM時，不需要重新布線可使整個網絡保持原有的拓撲結構。以上特點分層網絡結構可以獲 得良好的擴展性

4、，根據實際需求，整個企業(yè)網采用星型結構，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。由云到D座樓為A類網，由D座樓到各個樓之間為B類網，各個內部為C類網。對于整個網絡的拓撲結構為混合型結構，以路由器為網絡中心的星型結構，各 部門以交換機為主結點的樹型結構。由于計算機與網絡技術的特殊性，網絡建設需要考慮以下一些因素：系統的先 進性、體統的穩(wěn)定性、系統的可擴展性、系統的可維護性、應用系統和網絡系統的 配合度、與外界網絡的連通性、建設成本的可接受度等。2.1.3具體設計表1校園網設備選擇表樓座設備型號數量A座樓RouterRouter-PT1Switch2960-242P
