ADSL技术应用的设计与实现
摘 要：随着通讯技术的迅速发展，上网用户的不断增加，骨干网络的传输速度已经得到很大提高。而相比之下接入网的传输速率却始终是1个瓶颈，ADSL技术的出现很好地解决了这“最后1公里”接入瓶颈问题。
本论文主要研究了通过电信网络实现ADSL宽带接入到普通个人用户，和实现组建在地理上比较分散的企业内部专线网络技术。论文首先介绍了ADSL技术的应用背景、技术特点和DSL技术，然后结合相关业务介绍了其他网络技术和常用设备，比如ATM技术、PPPoE、RADIUS、DSLAM、BAS等，最后设计与实现了ADSL技术的两种典型应用方式：PPPoE虚拟拨号和极速通业务。在虚拟拨号的设计中主要完成了用户端ADSL Modem的'配置，局端对RADIUS服务器的验证、授权、计费等设置，以及对华为8825BAS的配置。在极速通业务中，主要完成了对华为8825 BAS，中兴8820 DSLAM的配置。
本设计解决了1些常见的市场需求，具有1定的应用价值。

ADSL Technology Application’s Designation and Relization
Abstract：With the rapid development of communication technology, Internet continues to increase, and the transmission speed of the backbone networks has been greatly enhanced. However, compared to the transmission speed, the transmission rate of access networks has always been a bottleneck. ADSL technology provides us with a very good technical solution of the “last kilometer” access bottleneck. This paper mainly analyses the connection of ADSL broadband with the ordinary individual users through telecommunication and the achievement of establishing a geographically dispersed enterprises internal lane networks technology. At first, it introduces the applicable background and technology characteristics of ADSL technology and DSL technology.
Then, in the relevant operational network technology, it introduces other networks technology and usual equipment, for example, ATM technology, PPPoE, DSLAM, BAS and so on. Finally, it designs and realizes two typical applications of ADSL: PPPoE virtual dial-up and rapid-business. In the design of virtual dial-up, ADSL modern configuration, the authentication of different terminal to RADIUS, authorization, expense counting and Huawei 8825BAS configuration are mainly completed. In the rapid-business, the configuration of Huawei 8825 BAS and Zhongxing8820 DSLAM are completed. The design solves some of the common market demand and it has a certain applicable value.
Keywords: ADSL; DSL; ATM technology; PPPoE virtual dial-up; Rapid-business
