Protocol for Access Node Control Mechanism in Broadband Networks
Abstract
This document describes the Access Node Control Protocol (ANCP).
ANCP operates 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 Quality of Service, service, and subscribers. Use cases
for ANCP are documented in RFC 5851. As well as describing the base
ANCP protocol, this document specifies capabilities for Digital
Subscriber Line (DSL) topology discovery, line configuration, and
remote line connectivity testing. The design of ANCP allows for
protocol extensions in other documents if they are needed to support
other use cases and other access technologies.
ANCP is based on the General Switch Management Protocol version 3
(GSMPv3) described in RFC 3292, but with many modifications and
extensions, to the point that the two protocols are not
interoperable. For this reason, ANCP was assigned a separate version
number to distinguish it.
