Broadband Forum Releases Open Broadband-Broadband Access Abstraction (OB-BAA) Code

The Broadband Forum has taken a step toward establishing norms and standards in the cloud with the first code release and documentation of its Open Broadband-Broadband Access Abstraction (OB-BAA) project. The highly technical work aims to ease what today are difficult business and planning decisions.

The OB-BAA is aimed at enabling co-existence among an ever-increasing variety of software-defined access models. “OB-BAA enables operators to optimize their decision-making process for introducing new infrastructure based on user demand and acceptance instead of being forced into a total replacement strategy,” Broadband Forum CEO Robin Mersh in a press release. “By reducing planning, risks and execution time, investment in new systems and services can be incremental.”

OB-BAA specifies northbound and southbound interfaces and core components for functions used by virtualized access devices. Its standardized layered approach is customized for SDN automation. The key is that it decouples device and software implementation choices from business and market decisions. This eases what previous were difficult planning steps.

The OB-BAA will be integrated into the Broadband Forum’s CloudCO Architectural Framework (TR-384) and will complement industry work at ONF and elsewhere. “The first release of OB-BAA marks a major milestone for the industry,” Tim Carey, Lead Technology Strategist at Nokia and Chair of the Broadband Forum’s BAA project said in the press release. “It delivers an open reference implementation based on standards-compliant interfaces, that operators and vendors worldwide can use to develop and deploy interoperable cloud-based access networks more easily and quickly.”

Companies involved in the project include Broadcom, BT, Calix, CenturyLink, China Telecom, Huawei, Nokia, Telecom Italia, Tibit, ZTE and the University of New Hampshire InterOperability Lab (UNH-IOL).

More releases, consisting of code and documentation, are planned. The data is available at The Broadband Forum has published an OB-BAA overview paper and will hold a webinar on August 29 describing OB-BAA featuring service providers and vendors.
