Abstract

The multiple revenue possibilities provided by the IP based networks stimulate the Internet Service Providers and Telecom Providers to move to ADSL Transport Networks that are entirely IP based. Ethernet/PPP traffic is also attractive because it provides authentication, security and accounting features. These types of traffic can become a common presence in ADSL networks by devising DSLAMs that are able to extract the IP and Ethernet traffic inside the DSLAM itself. The paper propose a DSLAM architecture that can accomodate a large range of deployments and uses advanced learning techniques to optimize its performances. A prototype of this architecture was implemented on a platform based on Intel IXP 2350 network processor and the obtained test results shows that the architecture is ready for a production implementation.
