Open-source Virtual Broadband Network Gateway (vBNG) as a Software for Open Networking in the Cloud (SONiC) app for ISPs

Traditional BNG deployments often rely on proprietary and hardware-dependent solutions, leading to vendor lock-in, limited scalability, and challenges in adapting to evolving network requirements. The project addresses these issues by leveraging SONIC NOS and its open-source nature to develop a virtual BNG solution that is hardware-agnostic, scalable, and flexible.

The primary objective is to create a virtual BNG solution that decouples the software from hardware specifics, allowing it to run on various hardware platforms and switch ASICs supported by SONIC NOS. This hardware independence promotes vendor choice, scalability, and the ability to leverage new hardware innovations without disruption. Then design and develop a vBNG architecture that can scale seamlessly based on network demands. By leveraging the capabilities of SONIC NOS and its integration with the SAI interface, the vBNG solution can efficiently handle a large number of subscribers, adapt to changing network conditions, and support dynamic service provisioning.

integrate the vBNG software seamlessly with SONIC NOS, utilizing the SAI interface to interact with switch ASICs. This integration enables the vBNG to control and manage the underlying hardware components, including packet forwarding, QoS policies, and other hardware-specific operations.

The project seeks to implement robust subscriber management functionalities, including authentication, authorization, and accounting (AAA), as well as service provisioning and policy enforcement. The vBNG solution will support various authentication methods, handle subscriber sessions, enforce policies, and provide network services to connected subscribers.

Performance Optimization and Efficiency: The objective is to optimize the performance and efficiency of the vBNG solution by leveraging hardware acceleration, intelligent traffic management, and QoS mechanisms. By efficiently utilizing the capabilities of switch ASICs and the SAI interface, the vBNG can deliver high throughput, low latency, and effective resource utilization.

The project promotes collaboration and community engagement within the SONIC ecosystem. It aims to contribute back to the SONIC open-source community by sharing enhancements, best practices, and experiences gained during the development of the vBNG solution. This collaboration fosters innovation, knowledge exchange, and community-driven improvements.
