中山大學(xué)計(jì)算機(jī)網(wǎng)絡(luò)畢業(yè)論文:WLAN技術(shù)在園區(qū)網(wǎng)的應(yīng)用

  摘 要

  隨著WLAN技術(shù)的迅速發(fā)展和工業(yè)園區(qū)強(qiáng)勁的互聯(lián)需求,在園區(qū)內(nèi)建立便捷、高效、安全的WLAN網(wǎng)絡(luò)成為一個(gè)熱點(diǎn)課題。如何選擇合適的WLAN標(biāo)準(zhǔn)和設(shè)備、如何在實(shí)際環(huán)境中部署WLAN網(wǎng)絡(luò)這些問題成為WLAN應(yīng)用中不可回避的難點(diǎn)。本文首先將對(duì)WLAN技術(shù)的相關(guān)概念及國(guó)內(nèi)外發(fā)展情況進(jìn)行分析。其次,筆者結(jié)合WLAN體系的基本要件,對(duì)某小型園區(qū)的WLAN體系構(gòu)建進(jìn)行詳細(xì)和分析。再次,筆者就園區(qū)無線網(wǎng)絡(luò)建設(shè)中的統(tǒng)一認(rèn)證問題進(jìn)行分析和解釋,建議采用集中化的用戶認(rèn)證、加密和訪問控制器機(jī)制,所有的用戶身份認(rèn)證都將通過無線控制器來實(shí)現(xiàn),從而解決了將無線網(wǎng)絡(luò)系統(tǒng)與園區(qū)認(rèn)證系統(tǒng)的無縫整合。最后,筆者根據(jù)實(shí)際網(wǎng)絡(luò)布置和調(diào)試中的經(jīng)驗(yàn)結(jié)合自身的工作和學(xué)習(xí)經(jīng)歷,總結(jié)WLAN技術(shù)在園區(qū)網(wǎng)應(yīng)用中的難點(diǎn)和解決措施。

  Abstract

  With the rapid development of WLAN technology and increase of strong demand for interconnection, it becomes a hot topic for creating a convenient, efficient, and safe and   networks in industrial parks., these problems such as how to choose the right WLAN standards/equipments and deploy WLAN networks in a real environment constructs unavoidable difficulties in WLAN applications. Firstly WLAN technology concepts and developments at home and abroad will be analyzed; secondly, the author combines the basic elements of the WLAN system in detail and analysis of a small park WLAN System. In addition, the author analyses and interprets the unified certification issues in the park wireless network construction, it is recommended that a centralized user authentication, encryption and access control mechanisms are necessary for the stable and convenience management. All user authentications will be achieved through a wireless controller, so as to solve the seamless integration of wireless network system with the park authentication system. Finally, according to the actual network layout and debugging experience, together with the combination of work and learning experience, the author sums up the difficulties and solutions of WLAN technology in the industry parks network applications.
