"Framework and Requirements for an Access Node Control Mechanism in Broadband Multi-Service Networks", Sven Ooghe, Norbert Voigt, Michel Platnic, Thomas Haag, Sanjay Wadhwa, 27-Jul-09. ( bytes)

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 QoS-related, service-related and Subscriber-related operations. The Access Node Control Mechanism will ensure that the transmission of the information does not need to go through distinct element managers but rather using 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 (OSSes). 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 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.

"Security Threats and Security Requirements for the Access Node Control Protocol (ANCP)", Hassnaa Moustafa, Hannes Tschofenig, Stefaan De Cnodder, 9-Jul-09. ( bytes)

The Access Node Control Protocol (ANCP) aims to communicate QoS- related, service-related and subscriber-related configurations and operations between a Network Access Server (NAS) and an Access Node (e.g., a Digital Subscriber Line Access Multiplexer (DSLAM)). The main goal of this protocol is to allow the NAS to configure, manage and control access equipments including the ability for the access nodes to report information to the NAS. The present document investigates security threats that all ANCP nodes could encounter. This document develops a threat model for ANCP security aiming to decide which security functions are required. Based on this, security requirements regarding the Access Node Control Protocol are defined.

"Protocol for Access Node Control Mechanism in Broadband Networks", Sanjay Wadhwa, Jerome Moisand, Swami Subramanian, Thomas Haag, Norber Voigt, Roberta Maglione, 13-Jul-09. ( bytes)

This document describes proposed extensions to the GSMPv3 protocol to allow its use in a broadband environment, as a control plane between Access Nodes (e.g. DSLAM) and Broadband Network Gateways (e.g. NAS). These proposed extensions are required to realize a protocol for "Access Node Control" mechanism as described in [ANCP-FRAMEWORK]. The resulting protocol with the proposed extensions to GSMPv3 [RFC3292] is referred to as "Access Node Control Protocol" (ANCP). This document currently focuses on specific use cases of access node control mechanism for topology discovery, line configuration, and OAM as described in ANCP framework document [ANCP-FRAMEWORK]. It is intended to be augmented by additional protocol specification for future use cases considered in scope by the ANCP charter. ANCP framework document [ANCP-FRAMEWORK] describes the ANCP use-cases in detail. Illustrative text for the use-cases is included here to help the protocol implementer understand the greater context of ANCP protocol interactions.

"Access Node Control Protocol (ANCP) MIB module for Access Nodes", Stefaan De Cnodder, Moti Morgenstern, 31-Jul-09. ( bytes)

This memo defines a portion of the Management Information Base (MIB) for use with network management protocols. In particular it defines objects for managing access nodes that are using the Access Node Control Protocol (ANCP).

"Additional Multicast Control Extensions for ANCP", Francois Le Faucheur, Roberta Maglione, Tom Taylor, 6-Jul-09. ( bytes)

This document specifies the extensions to the Access Node Control Protocol required for support of the multicast use cases defined in the Access Node Control Protocol framework document.
