Open Broadband network gateway (open bng) software speeds up internet connection speeds by managing the bandwidth of a local area network. It is a piece of software that manages the bandwidth in a small area, such as an office building or apartment block, providing faster internet for users. 

With the increased demand for faster Internet connectivity and its widespread usage, there is an increased need for Open BNG software to manage bandwidth efficiently in densely populated areas where there are numerous users sharing one ISP connection.

Users are now opting for fast internet services like fiber optic, cable, and LTE with upload and download speeds that have gone up tremendously. But these upgraded connections put additional strain on existing routers and switches that can’t handle so much data at once. This blog will tell you everything you need to know about Open BNG.

What is Open BNG?

Open bng was created as a result of a collaboration between Telefónica, Deutsche Telekom, BT, and Vodafone with large scale fiber-to-the-home (FTTH) networks as part of the Telecom Infra Project (TIP). In the past, carrier routing systems have been delivered as monolithic systems with integrated hardware and software. It is difficult to automate legacy systems, and carriers are locked into different platforms for each service they provide. Open BNG proposes the separation of hardware and software, as well as open interfaces that are simpler to control from external systems.

The goal of open bng is to develop solutions that resolve some of the most significant problems operators are currently facing when deploying fixed access services to a wide range of customers.  Disaggregated solutions are contributing to the development of open bng, allowing for faster network transformation and greater connectivity. Costs will be reduced, while revenues will rise, and efficiency will be improved.

How does it work?

Open networking is one of the underlying drivers for BNG disaggregation;  separating BNG control and data planes will help operators centralize management, enhance performance, and achieve greater flexibility in operations, including real-time scaling.

Due to the Open BNG’s distributed architecture, access nodes are directly connected to business customer edge nodes as well as mobile backhaul. Open BNG will normally handle VLANs on the access network, but it will also need to be able to act as a full router on the mobile backhaul and, of course, the aggregate network, which is why the Provider Edge SW packages are required. It is also used for enterprise VPN services, which is why the Open BNG package also includes the PE SW package.  If a Master Clock device is located above the open bng, the access node must satisfy the same synchronization requirements as the MBH. Furthermore, this standard requires following the SDN concepts. 

BNG is less distributed and does not form an integral part of the aggregation network, rather it serves as a service node that is connected to the aggregation network. Using a “Service Node” approach puts much more emphasis on terminating subscribers within a tunnel of some sort. There is a requirement for router and PE functionality, but there is also the option to deploy separate BNG for enterprise (with routing and PE functionality) and consumer (without PE functionality). As this type of BNG must aggregate between 32k and 128k subscribers, it is not critical that it supports time/phase synchronization for mobile backhaul, as this can instead be handled through the aggregation network. This case is also suitable for a pure software BNG 2 that employs a general purpose computer.

The Open BNG node is made up of commercial off-the-shelf hardware (bare metal switches) and open software (Network Operating System – NOS) and interfaces (solutions that use software forwarding rather than bare metal switches may also be appropriate in the ‘Service BNG’ case).  In this context, disaggregation in this specification refers to the separation of hardware and software. More vertical separation of the software stack is strongly encouraged for improved programmability and SDN support.

Central Offices will be the only places where the Open BNG hardware platform will be deployed. Installed racks will typically be 600 mm wide, 800 mm deep, and 600 mm  or 800 mm wide. Typically, OpenBNG hardware will have a 2U form factor. In order to increase scalability, platform stacking could be considered. The equipment must meet, or exceed, the requirements of ETSI standard ETS 300 019-1-3 (Class 3.1), in particular with respect to temperature (from -5°C to +45°C). Additionally, the equipment must conform to all applicable standards regarding mechanical, electrical, and safety conditions, as well as all directives and certifications required in the country where it will be used.

The Benefits of Open BNG

  1. Through open bng, updated features and services are made available to customers through the network.  Thus, the delivery of new products and services is faster, as well as offering customers a wider array of options.
  1. Vendor lock-in will not be an issue. A more diverse ecosystem of suppliers can be accessed by operators after ye
  1. Broadband network operators can choose from a variety of hardware and software functions with open bng.
  1. By allowing deployment methods such as centralized, distributed, or standalone BNG, as well as BNG with a router, lower total cost of ownership results in a cheaper per-subscriber cost and less reliance on monolithic providers.

Conclusion

By developing modern, secure, and open technologies based on open, standardized interfaces, OpenBNG is helping to fill this gap in the market. A wide range of suppliers will be able to provide these new technologies, improving supply chain diversity and unlocking new business opportunities across the fixed-line and wireless value chains.

It is a collective endeavor to define industry standards that enable interconnection, competition, and global supply chains that have helped drive the telecommunications industry to its strength. As a result, the TCO of service providers will improve, and higher value services can be tailored for their customers. With an open disaggregated architecture, TIP has had a huge impact on service providers.
