Protocol for Access Node Control Mechanism in Broadband Networks
2011
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. [STANDARDS-TRACK]
