Access Node Control Protocol (ANCP)

A Layer 2 TCP protocol facilitates communication between access nodes like digital subscriber line access multiplexers (DSLAMs) and Layer 3 subscriber-aware controllers such as broadband remote access servers (BRAS) or network-attached storage (NAS). This protocol is crucial in managing the data flow between these different layers of the network, ensuring efficient and reliable transmission of information. It plays a pivotal role in bridging the gap between physical network hardware and higher-level data handling, making it essential for the smooth functioning of broadband networks.
