Target: The Access & Transport Architecture (ATA) Work Area maintains primary architectural work of the Broadband Forum. The group delivers scalable, dynamic, and flexible architectures to support highly resilient connectivity for the next-generation of responsive services and applications. ATA’s focus includes specifying frameworks and real-time tools to deliver predictive connectivity and service performance.
Progress: The group’s work on quality and performance measurements continues with discussions on service metrics, QED in multicast environments, and QED measurement formats.
The publication of TR-390 Issue 2 Amendment 1 has laid the foundations for performance measurement using STAMP in access networks. This has helped enable a new Open Broadband project: OB-STAMP for improved Quality of Experience.
The group has made considerable progress on the architecture of ‘Subscriber Session Steering’ WT-474. Alongside this, the Open Broadband Subscriber Session Steering (OB-STEER) project has been proposed for automation delivery, greater efficiency, and traffic optimization.
‘IP Capacity Metrics and Measurement’ WT-471 Issue 4 was sent to Straw Ballot, ‘Control and User Plane Separation for a disaggregated BNG’ WT-459 Issue 3 has completed Straw Ballot resolution, and ‘Wi-Fi Authentication’ WT-497 has proceeded to Final Ballot.
A new project on ‘Security Considerations for IPv6 Broadband Networks’ has been approved, with a new project on ‘Multicast delegation for Live TV streaming’ discussed. The latter would enable video providers to leverage network multicast capabilities and assure an end-to-end digital supply chain.
