The IESG has approved the following document: - 'Framework and Requirements for an Access Node Control Mechanism in Broadband Multi-Service Networks ' <draft-ietf-ancp-framework-12.txt> as an Informational RFC This document is the product of the Access Node Control Protocol Working Group. The IESG contact persons are Ralph Droms and Jari Arkko. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-ancp-framework-12.txt Technical Summary 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 draft lays down a framework for the protocol. It describes the use-cases and likely deployment scenarios as well as outlining the functionality that the protocol will have to provide to support these. The document is INFORMATIONAL and is a product of the ANCP working group. Working Group Summary The origin of the draft can be traced back to the WT-147 "Layer 2 Control Protocol" document from the Broadband Forum. The WG spent some time in revising that draft and fine-tuning use-cases and terminology. A fair bit of WG discussions occurred regarding the scope of the "multicast control use-cases", and how these relate to a policy system architecture. In this, debate mainly focused on the bandwidth admission control functionality aspects of the Access Node and the NAS. So as to arrive at rough consensus a number of options ended up being described in the draft. Document Quality The document is a protocol framework, with the protocol being specified in a separate WG draft (draft-ietf-ancp-protocol). The latter has a number of implementations.
