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 ATA Work Area published the ‘Public Wi-Fi User Authentication and Data Local Forwarding Technical Requirements’ TR-497 which will enable Wi-Fi devices developed by device manufacturers to be uniformly authenticated by an Access Controller, but with data being forwarded locally.
A new project on ‘Application of L4S to Broadband Networks’ has been approved, to define how to implement L4S capability into a broadband network. This will allow service providers to offer services that can support the requirements of latency sensitive applications at the same time as the throughput sensitive applications.
Work has begun on ‘Security Considerations for IPv6 Broadband Networks’ WT-515, which aims to provide development considerations and enhance IPv6 security measures for the communication of multiple devices over a network.
Progress was made on a number of projects, with ‘IP Capacity Metrics and Measurement’ WT-471 Issue 4 entering Final Ballot and ‘Control and User Plane Separation for a disaggregated BNG’ WT-459 Issue 3 expected to complete Straw Ballot imminently.
The work area has also continued to make progress on the architecture of ‘Subscriber Session Steering’ WT-474. Joint sessions were held with the SDN/NFV Work Area to review WT-474 and WT-459 in the context of the CloudCO architecture.
The Performance, Experience, and Application Testing (PEAT) Project Stream worked on In-Situ OAM in the QED framework (WT-452), which will enable greater insights of the latency at intermediate points of the network.
