[工学]ADSL技术及应用-PPPoE的实现.doc

摘要[1]宽带接入网即通过PPPoE[2]虚拟拨号连接互联网将成为当今社会人们分享互联网，进行信息交流的主要方式。本文将全面阐述实现用户线路高速化的ADSL的技术以及应用，并介绍ADSL宽带接入技术及其特点几种常用的ADSL应用方式，并将其与目前流行的几种接入方式Modem，ISDN[3]，Cable Modem和DDN进行了对比PPPoE协议同时也将WAN[5]支持部分、TAPI支持部分、链路控制、PPPoE支持、发送/接收机制、同应用程序接口机制在网络拨号程序中的工作原理PPPoE发现PPPoE协议支持相关算法的源代码，提出更有效、更安全的数据发送和接收算法。关键词ADSL ；PPPoE协议驱动程序 Abstract Get to connect into the technical and fast fierce development in net along with information technique and breadths, ADSL breadth takes to connect into the net to pass the PPPoE namely conjecture stirs the number conjunction Internet will become the shared Internet in social people in now, proceeding the main way of the information exchanges.This text will expatiate the ADSL that realizes technique and applications that customer circuit high speed turn completely, will still introduce the breadth of ADSL take to connect into the technical developing process and its characteristics, advantage, system constructions gradually network construction, and a few and in common use ADSL application method with connect into the way, combine its connect into with current popular and several kinds the way Modem, ISDN, the Cable Modem( electric cable modem) proceeded the contrast with the DDN.This text will still introduce PPPoE agreement and its terraces takes the at every step thorough elucidation PPPoE for setting up, Windows system bottom PPPoE realizes project namely the customer of PPPoE carry software how realizes conjecture stir number internet access, also will under the Windows system negotiate how to makes use of the WAN support, TAPI support, LCP network control, PPPoE support, send out/ receive the mechanism, together applied the procedure connects a peoples mechanism etc. Everyones drives and the network negotiates to realize to stir the number process and its stir the number work in the procedure principle in the network.The PPPoE detection is a beginning step that PPPoE agreement mechanism proceeding data exchange, and is also to send out with accept the
