【正文】 畢業(yè)設計(論文 ) 題目: 園區(qū) 局域網(wǎng)設計與規(guī)劃 Title: Community Local Area Network Design and Planning 系 別: 軟件學院 專 業(yè): 網(wǎng)絡工程 學 號: 08114205 學生姓名: 董 巖 指導教師: 王 志 波 二 零 一 二 年 四 月 東華理工大學本科畢業(yè)設計(論文) 摘要 摘 要 近些年來 , 網(wǎng)絡技術的發(fā)展速度已經到達了令世界瞠目結舌的地步 , 并且網(wǎng)絡的發(fā)展越發(fā)的呈現(xiàn)出 廣泛化和深入化的特點。其中,在園區(qū)局域網(wǎng)的普及中最能體現(xiàn)這兩點,在目前的社會環(huán)境中,想要參與到工作、學習中都離不開網(wǎng)絡的支持 , 網(wǎng)絡技術對于人類社會的巨大印象已經越來越成為一個世界性的課題。本文首先介紹了有關網(wǎng)絡的一些基本概念知識,讓讀者對網(wǎng)絡技術的框架有一個初步的了解,然后對園區(qū)局域網(wǎng)的現(xiàn)狀及未來進行分析,進而討論了在設計和實現(xiàn)園區(qū)局域網(wǎng)的規(guī)劃時所要考慮的主要因素,最后給出了實現(xiàn)園區(qū)局域網(wǎng)的具體實現(xiàn)計劃和操作規(guī)程 , 這一部分包括邏輯拓撲、物理拓撲的規(guī)劃 , 虛擬局域網(wǎng)( Virtual Local Area Network,VLAN) 劃分 , IP 地址規(guī)劃以及小區(qū)局域網(wǎng)所具有的功能。 園區(qū)局域網(wǎng)是基于分層網(wǎng)絡架構而設計的,實現(xiàn)了域名解析系統(tǒng) ( Domain Name System, DNS) 、動態(tài)主機配置協(xié)議 ( Dynamic Host Configuration Protocol,DHCP) 、網(wǎng)絡地址轉換 ( Network Address Translation,NAT) 等基本服務并啟用認證授權記賬 ( Authentication Authorization Accounting, AAA) 服務。園區(qū)內部企業(yè)的遠程用戶可 以通過虛擬專用網(wǎng)絡 ( Virtual Private Network, VPN)穿越 Inter 與園區(qū)內企業(yè)進行通信 , 移動用戶可以通過 PPPoE 撥號接入訪問Inter 資源。園區(qū)內部各 VLAN 之間通過動態(tài)路由協(xié)議連通。劃分 VLAN 可以進行流量控制,并在一定程度上提高了網(wǎng)絡傳輸?shù)陌踩?,但為了維護 VLAN 信息的一致,各樓棟內接入交換設備采用 VLAN 中繼協(xié)議 ( VLAN Trunking Protocol,VTP) 。園區(qū)內還采用鏈路聚合技術增加網(wǎng)絡冗余,以提高網(wǎng)絡的穩(wěn)定性和負載均衡;出于安全角度的考量 , 維護人 員需通過安全外殼協(xié)議 ( Secure Shell,SSH)對園區(qū)設備進行遠程管理維護。 關鍵詞: 虛擬局域網(wǎng); 邏輯拓撲; 物理拓撲; 分層網(wǎng)絡; 域名解析系統(tǒng); 動態(tài)主機配置協(xié)議; 網(wǎng)絡地址轉換; 虛擬專用網(wǎng)絡; 動態(tài)路由協(xié)議; 鏈路聚合; 安全外殼協(xié)議 東華理工大學本科畢業(yè)設計(論文) ABSTRACT ABSTRACT In recent years, the pace of development of work technology has reached the point where the world is staggering, and the development of the work showing the more extensive and indepth features. Among them, the best in the popularity of the campus LAN reflected in the current social environment, you want to participate in work and learning are inseparable from the support of the work, work technology, a huge impression for the human society has bee increasingly bee a worldwide issue. This paper first introduces about your work some of the basic concept of knowledge, so that the reader a preliminary understanding on the framework of the work technology, then the status of campus LANs, and the future conduct analysis, and then discuss the design and to achieve campus LANs, and planning are to be consider Finally, a major factor, given the specific plans and operating procedures to achieve campus LAN, this part, including the planning of the logical topology, physical topology, virtual LAN (virtual Local Area Network, VLANs) division, IP address planning, as well as the LAN area has function. The munity local area work,which is based on the layered work architecture, achieves the Domain Name System(DNS),Dynamic Host Configuration Protocol(DHCP),Network Address Translation(NAT) and other basic services as well as enabling Authentication Authorization Accounting(AAA).The remote users in the munity business can municate with the enterprise across the Inter by a virtual private work(VPN), and the mobile users can have access to the Inter resources by PPPoE connectivity of the internal interVLAN in the munity e true by making use of dynamic routing VLAN is not only beneficial to traffic management,but also to some extent provides the work order to maintain the consistency of the VLAN information,all the swithing equipments in the building use the VLAN trunking protocol ,there is also taking full advantage of link aggregation to increase work redundancy and improve work stability and load view of safety,maintaince staff should be by virtue of secure shell protocol(SSH) for remote management and maintenance of equipment. Keywords:VLAN。 logical topology。 physical topology。 layered work architecture。 DNS。 DHCP。 NAT。 AAA。 VPN。 dynamic routing protocol。 link aggregation。 SSH 東華理工大學本科畢業(yè)設計(論文) 目錄 目 錄 第 1 章 緒論 ................................................................................................................ 1 課題背景 ......................................................................................................... 1 小區(qū)局域網(wǎng)的系統(tǒng)組成 ................................................................................. 1 小區(qū)局域網(wǎng)的基本功能 ................................................................................. 1 物業(yè)管理辦公自動化模塊功能 .......................................................... 2 小區(qū)綜合信息服務模塊功能 .............................................................. 2 家居服務模塊功能 .............................................................................. 2 日常生活資訊模塊功能 ...................................................................... 2 第 2 章 網(wǎng)絡概述 ........................................................................................................ 3 網(wǎng)絡分類 ......................................................................................................... 3 網(wǎng)絡體系結構 ................................................................................................. 3 OSI 參考模型 ....................................................................................... 4 TCP/IP 參考模型 ................................................................................. 4 OSI 參考模型與 TCP/IP 參考模型的比較 ......................................... 5 常用網(wǎng)絡連接設備 ......................................................................................... 5 網(wǎng)關 ( Gateway) ................................................................................ 5 路由器 ( Router) .............................................................................. 6 交換機 ( Switch) .............................................................................. 7 網(wǎng)橋 ( Bridge) .................................................................................. 8 集線器 ( Hub) .................................................................................... 8 中繼器 ( Repeater) .......................................................
