Abstract
Which enrichments are required for the DSL architecture to transform the DSL access network from a vehicle for best effort Internet access to a multiservice platform enabling added value conversational and data services? This article details an architecture for DSL access facilitating IP service guarantees leveraging the available QoS mechanisms in the transport-technology-specific data plane, while extending the control plane. Enhanced resource and information control, policy enforcement, and advanced IP connection establishment mechanisms are key elements for the network access provider to enter the value chain for delivery of IP services.
