Virtual BNG on Public Cloud for Disaster Recovery and Capacity on Demand (2023)

By Jim Huang, Amazon Web Services; Juan Luis Esteban, Ciena; Christopher Adigun, Amazon Web Services

Broadband Network Gateway (BNG) is a critical network component in broadband and Internet Service Provider networks. Its primary function is to manage and control the delivery of broadband services, such as internet access, to subscribers. The BNG technology has been evolving over the past two decades from specialized hardware devices to virtual BNG (vBNG) and further to disaggregated BNG (DBNG) with control plane and user plane separation (CUPS) as specified by Broadband Forum Technical Report TR-459[1]. The vBNG technology was driven by the need for more flexible solutions and higher operation efficiency through virtualizing BNG functions and running them as software on industry-standard hardware or virtual machines. The DBNG technology allows service providers to select and deploy individual components, instead of relying on monolithic integrated solutions. It enables service providers to optimize their network architecture and scale each component independently based on demand, allocating resources where they are needed the most and avoiding overprovisioning. This paper presents BNG cloudification – a broadband technology frontier built on vBNG and DBNG.Today, public cloud has been widely adopted by enterprises and industry verticals including telecommunications due to its economies of scale and capabilities for gaining operation efficiency, enabling business agility, as well as providing a wealth of latest technology services. The BNG cloudificationpresented in this paper is about running vBNG control plane and vBNG user plane in the public cloud.
