Multi-access broadband network gateway (BNG)

Deliver a seamless broadband experience everywhere

The Nokia multi-access broadband network gateway (BNG) lets you converge wireline and fixed-wireless access so you can deliver an affordable, reliable and seamless broadband experience to every customer.

What is a multi-access broadband network gateway?  

Broadband access is essential for enabling people to connect with each other and the cloud. But many homes and offices are underserved because no single access technology can cover all their connectivity needs. How can broadband service providers overcome this digital divide?

The BNG plays an essential role in delivering residential broadband services by managing and controlling network access policies for subscribers and connected user devices. Over the years, it has evolved from broadband remote access servers for dial-up internet and digital subscriber lines (DSL) to a versatile multi-access gateway that can aggregate a wide range of wireline and fixed-wireless access technologies.  

With our multi-access BNG, you can cost-efficiently expand connectivity and coverage for gigabit internet, IPTV, HD video streaming and conferencing, social media, online gaming, virtual team collaboration, and low-latency compute and storage in the multi-access edge cloud

The leading edge for the best broadband experience  

The multi-access BNG solution is based on our market-leading 7750 Service Router (SR) family, which is powered by our breakthrough FP network processor technology and proven Service Router Operating System (SR OS).  

The 7750 SR and SR-s edge routers use FP4 and FP5 silicon to support ultra-scalable subscriber management, granular bandwidth management and line-rate DDoS filtering. With these capabilities, your residential broadband customers can enjoy HD video content without glitches and play online games without lag spikes or disconnects. Telecommuters can access the cloud and conduct video conferences without hiccups. Everyone wins with a great broadband experience.

You can personalize and differentiate your broadband offer by deploying service appliances in the form of integrated line cards (ISA) or externally connected devices (ESA). Service appliances enhance the BNG user plane with value-added service functions such as network address and port translation (NAT), video quality monitoring (VQM), deep packet inspection (DPI) for assuring over-the-top applications, and stateful firewall services to restrict access to mature, malicious and unlawful web content.

How can you personalize and optimize your BNG? 

A flexible SR OS software licensing scheme lets you tailor BNG system features and functions to your specific access needs, service mix and deployment requirements. Model-driven APIs and Python scripting give you extensive programmability to customize service behavior and ensure that the BNG can interwork with back-end operations support systems.

The solution lets you choose integrated deployment on Nokia 7750 SR or virtualized service routers or disaggregated BNG deployment. The disaggregated BNG model adds operational flexibility by separating control and user plane functions based on open interface standards defined in Broadband Forum TR-459. This allows you to optimize bandwidth capacity and latency by distributing BNG user plane functions, and to virtualize and independently scale out control plane functions in a data center.
