The Broadband Network Gateway (BNG) is a subscriber management system that provides the means by which residential wireline subscribers connect tobroadband services provided either by the wireline broadband network operator (retail services) or through an Internet Service Provider (wholesale services).
Ericsson’s BNG is supported on the SSR 8000 edge router and the recent introduction of the router 8801. The BNG establishes and manages subscriber sessions, aggregates subscriber traffic and routes it to the network of the service provider. The BNG provides the following functions:
- Establish secure subscriber sessions between the Customer Premise Equipment (CPE) and the broadband services
- Authentication, Authorization and Accounting (AAA) of subscriber sessions through the AAA server
- IP address assignment through the DHCP server or local IP pools
- Policy management
- Quality of Service (QoS)
- High Availability providing both intra and inter-chassis redundancy
A service provider’s revenue comes from the edge of the network. The BNG is a key network component that ensures such revenue. Ericsson is an established leader in subscriber management chosen by 75% of the leading operators and by over 360 customers worldwide.
