Broadband Access Networks are composed of a wide variety of access technologies and transport protocols hindering end-to-end Quality of Service (QoS) provisioning. Protocol diversity could be overcome by defining appropriate internetworking protocols, but access technology diversity is more difficult to tackle. This problem could be mitigated by obtaining diagnostic information of each specific access technology in order to react upon events on each access link. Moreover, centralizing this information into an automated Operational Support System (OSS) would ease the management of the access network resources. Thereby, an appropriate framework for QoS control could be created. This paper presents a novel method to enable end-to-end QoS in Digital Subscriber Line (DSL) based access networks by integrating the DSL line information from the monitoring and diagnostic tools together with the resource management function of an automated OSS. With such a network architecture global end-to-end QoS can be established to support critical services like Internet Protocol Television (IPTV) and Voice over IP (VoIP). 1
