1、壺塞啞曳太堂王程硒±班究生堂位i金塞。．．擅堊摘要隨著寬帶接入網(wǎng)絡(luò)的迅猛發(fā)展，采用寬帶接入、認(rèn)證和計(jì)費(fèi)系統(tǒng)，建立一個(gè)可運(yùn)營(yíng)、可管理的寬帶網(wǎng)絡(luò)，已成為各網(wǎng)絡(luò)運(yùn)營(yíng)商的迫切要求。目前主要的以太網(wǎng)寬帶接入管理技術(shù)有PPPOE、DHCP+WEB、802．1x等。PPPoE是目前xDSL網(wǎng)絡(luò)和以太網(wǎng)接入中主流認(rèn)證協(xié)議，保留和繼承了PPP協(xié)議的特點(diǎn)。DHCP(DynamicHostConfigurationProtoc01)動(dòng)態(tài)主機(jī)配置協(xié)議是一個(gè)CLIENT到SERVER的協(xié)議。IEEE802．1x接入管理技術(shù)提供了一種用戶接入認(rèn)證的手段，它僅關(guān)注用戶端口的打開(kāi)與關(guān)閉。這三種技術(shù)各有特點(diǎn)，在應(yīng)用中需要根據(jù)
2、具體情況合理選擇，并設(shè)計(jì)合理的使用方案。為此，本文對(duì)三種以太網(wǎng)寬帶接入管理技術(shù)進(jìn)行了較為深入的研究，對(duì)它們的優(yōu)缺點(diǎn)給予充分的比較，規(guī)范了三種接入管理技術(shù)的適用領(lǐng)域，為未來(lái)以太網(wǎng)寬帶接入管理技術(shù)的選擇提供了理論依據(jù)。并且通過(guò)鄭州聯(lián)通公司的寬帶接入管理系統(tǒng)的案例研究，針對(duì)當(dāng)前所使用的DHCP+的接入管理方式存在的問(wèn)題，做了深入的分析，提出了合理的優(yōu)化方案。此外，論文還分析了電信級(jí)口寬帶網(wǎng)認(rèn)證技術(shù)存在的問(wèn)題，給出了可選的解決方案。論文的研究成果已被采納，應(yīng)用效果達(dá)到了預(yù)期目標(biāo)。關(guān)鍵詞：以太網(wǎng)；寬帶；接入管理AbstractWiththerapiddevelopmentofbroadbandtech
