Take the right road to open access networks

I’ve written before on our blog about the growing importance of open source and getting the balance right between open and standardization. Now the Broadband Forum (BBF) has taken a bold step in the right direction. And Nokia is right at the heart of it. This August BBF published the first official release of the Open Broadband-Broadband Access Abstraction (OB-BAA) project with Nokia as a leading contributor. This project increases operator confidence in multivendor innovation at the device and network service layers to create open broadband access networks.Tune in for the upcoming BBF webinar and get introduced to the project by the leaders of the BAA team.

OB-BAA combines open source practices with the BBF’s goal of developing large-scale standardized solutions for the industry. It defines a functional view of access nodes, abstracting device-specific implementations and exposing common northbound interfaces to an Software-Defined Networking (SDN) management and control layer. This abstraction increases the management interoperability between solutions and does away with development costs associated with implementing different interfaces for different system implementations.

With OB-BAA, for example, a service for a fiber-to-the-home subscriber can be configured without needing to know the Optical Line Terminal (OLT) and Optical Network Unit (ONU) hardware designs, or even the specific Passive Optical Network (PON) technology deployed.

OB-BAA reduces:

  • the cost of system engineering and system integration by suppliers and service providers.
  • the cost of operations with a standardized interface for SDN management and control.
  • the risks of deploying gigabit access by utilizing Open Broadband for testing and staging.

At Nokia, we believe this is an opportunity and incentive for innovation. That’s why we’ve contributed more than 140,000 lines of code to this project. With a reference open source implementation, we can focus on innovation in the service layer that brings the most value to operators. Equipment vendors and service providers can use and extend the software platform to build management and control layers independent from the hardware platform.

Nokia already has the Nokia Altiplano solution, a scalable commercial framework that is built to leverage exactly the type of open source software represented by OB-BAA. Altiplano reduces the risk of introducing new technologies and allows investment in new systems and services to be incremental.

nbn is a leading example of taking the open road. We’re working with nbn to show how Nokia’s Software Defined Access Network (SDAN) solutions, which has Altiplano as a core component, can help them scale operations across all devices in the field and roll out services more quickly.

OB-BAA is a great next step down the open road and it goes a long way to establishing a reference case for open source.
