Digital Subscriber Line (DSL) technology is widely deployed for Broadband Access for Next Generation Networks. Several documents like Broadband Forum TR-058 [TR-058], Broadband Forum TR-059 [TR-059], and Broadband Forum TR-101 [TR-101] describe possible architectures for these access networks. The scope of these specifications consists of the delivery of voice, video, and data services. The framework defined by this document is targeted at DSL- based access (either by means of ATM/DSL or as Ethernet/DSL). The framework shall be open to other access technologies, such as Passive Optical Networks using DSL technology at the Optical Network Unit (ONU), or wireless technologies like IEEE 802.16. Several use cases such as Access Topology Discovery, Remote Connectivity Test, and Multicast may be applied to these access technologies, but the details of this are outside the scope of this document.

Framework and Requirements for an Access Node Control Mechanism in Broadband Multi-Service Networks
The purpose of this document is to define a framework for an Access Node Control Mechanism between a Network Access Server (NAS) and an Access Node (e.g., a Digital Subscriber Line Access Multiplexer (DSLAM)) in a multi-service reference architecture in order to perform operations related to service, quality of service, and subscribers. The Access Node Control Mechanism will ensure that the transmission of the information does not need to go through distinct element managers but rather uses a direct device-device communication. This allows for performing access-link-related operations within those network elements, while avoiding impact on the existing Operational Support Systems.
This document first identifies a number of use cases for which the Access Node Control Mechanism may be appropriate. It then presents the requirements for the Access Node Control Protocol (ANCP) that must be taken into account during protocol design. Finally, it describes requirements for the network elements that need to support ANCP and the described use cases. These requirements should be seen as guidelines rather than as absolute requirements. RFC 2119 therefore does not apply to the nodal requirements.
