Understanding BNG
Broadband Network Gateway (BNG) is the access point for subscribers, through which they connect to the
broadband network. When a connection is established between BNG and Customer Premise Equipment (CPE),
the subscriber can access the broadband services provided by the Network Service Provide (NSP) or Internet
Service Provider (ISP).
BNG establishes and manages subscriber sessions. When a session is active, BNG aggregates traffic from
various subscriber sessions from an access network, and routes it to the network of the service provider.
BNG is deployed by the service provider and is present at the first aggregation point in the network, such as
the edge router. An edge router, like the Cisco ASR 9000 Series Router, needs to be configured to act as the
BNG. Because the subscriber directly connects to the edge router, BNG effectively manages subscriber access,
and subscriber management functions such as:
• Authentication, authorization and accounting of subscriber sessions
• Address assignment
• Security
• Policy management
• Quality of Service (QoS)
