Broadband Network Gateway (BNG): Overview

Broadband Network Gateway (BNG) provides capabilities that help to improve the service provider's
ability to manage the subscriber's services, and simplify overall network operations. BNG is a
functionality that comprises subscriber management at a logical aggregation point in the netw ork, which
manages the subscriber’s user experience through identification, address assignment, authentication,
authorization, accounting, and various other features such as security, Quality of Service (QoS), and
subscriber forwarding.
BNG represents the subscriber as a session, which is a logical point to enable services for a given
subscriber. A subscriber is usually identified with the protocol that provides the IP address of the
subscriber for address assignment. For example, a subscriber that uses the Point-to-Point Protocol (PPP)
to connect to the network, receives its IP address through the PPP IP Control Protocol (IPCP)
negotiation, and is represented as a PPP session. A subscriber that uses Ethernet to connect to the
network receives its IP address through Dynamic Host Control Protocol (DHCP) and i s repre sent ed a s
an IP session.
The purpose of deploying BNG at the provider edge is to better manage and enrich the subscriber
experience.
BNG separates subscriber access functions from provider services a nd yield s t hese be nefits:
• Comprehensive session management and billing functions are supported by means of
communication with an authentication, authorization, and accounting (AAA) server that is separate
from the BNG.
• Subscribers can obtain services based on their subscriber ID or a combination of their subscriber ID
and access line.
