Penetration of Digital Subscriber Line (DSL) broadband access has significantly increased over the last few years. Acceptance of DSL access is not only related to high speed Internet access that DSL technologies enable, but also to other services that can be offered over DSL lines, such as voice telephony, television broadcast and video-on-demand. Simultaneous offer of voice, video and data services over broadband access is commonly called “triple-play”. As triple-play services migrate to IP bearer, DSL providers are looking for ways of deploying IP based DSL access networks. Implementation of Quality of Service (QoS) mechanisms in IP based DSL access networks has become a prerequisite for assurance of quality delivery of real-time triple-play services. High bandwidth needs require an optimization of transport functions for triple-play services within DSL network. This article proposes cost optimized architecture for IP based DSL access network. It deals with principles that ensure quality delivery of real-time and delay sensitive triple-play services carried over IP. Solutions for bandwidth efficient and reliable transport functions in DSL access network are discussed, using Ethernet and SDH protocols. |
