在公用网络上提供专用网服务的技术,已成为当前网络技术研究的热点之一。而构架在公用网络之上的专用网的性能直接取决于宽带数据接入技术。文章对基于ATM方式的ADSL宽带接入技术进行了探讨,分析了该方式开展业务的特点,给出了一种基于ATM方式的ADSL宽带接入技术来构建虚拟专网的实现方案。
The technology of providing private network service on the public network has become one of the hot spots in current network technology research. The performance of a private network based on a public network depends directly on the broadband data access technology. This paper discusses the ADSL broadband access technology based on ATM, analyzes the characteristics of the way to carry out business, and presents a realization scheme of constructing ADSL based on ATM ADSL broadband access technology.
