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.
The BNG effectively manages subscriber access, and subscriber management functions such as:
• Authentication, authorization and accounting of subscriber sessions
• Address assignment
• Policy management
• Quality of Service (QoS)
This talk will go through some of the design considerations when deploying a BNG function to a network.
