Broadband Area Community Meetup Berlin, May 2022

I recently returned from an invigorating and productive set of open broadband community meetings in Berlin, where it was absolutely wonderful to see everyone again.  We didn’t know what the appetite would be for gathering in person, but the event was oversubscribed and we had a great turnout. 

It had been 3 years since the last broadband meetup. In fact, it had been so long that there were over a dozen people that I had only gotten to know over zoom during the last few years. There were even a number of individuals who had switched companies while remaining active in the community (which I would say is a sign of a pretty vibrant ecosystem)!

On day 1 we kicked off with a smaller broadband area leadership workshop with those companies most active in the ONF broadband community. Our purpose was to explore the formulations of a new leadership structure for the newly formed Broadband Area of the ONF.

We had strong community participation from DT, Radisys, Zyxel, Intel, Reply, Bell Canada, APS, Telefonica, Adtran
(and TIM and Vodafone - not captured in photo)

The energy of getting back together was palpable.  I had almost forgotten how much more can be communicated and accomplished in person, over dinner and with informal side conversations.

It was agreed that this new broadband area would focus on 4 projects and workstreams, each of which received enthusiastic backing from the leadership for continued investment, including:

  • VOLTHA – the disaggregated white box PON (OLT+ONU) solution currently in deployment with three tier 1 operators worldwide.
  • SEBA – the Reference Design (architecture) for building open disaggregated broadband solutions. The group identified a desire to see SEBA expanded to further cover BNG functionality.
  • SD-BNG – open source BNG (broadband network gateway) functionality, including flexibility for different hardware implementations (x86, P4, DPU/IPU) and converged mobile user planes (BNG + UPF, or AGF).
  • Alignment with Broadband Forum (BBF) – providing APIs for plugging VOLTHA into a BBF Cloud-CO framework.

The first day ended with a social and dinner, which brought together all 40+ community members attending the event. We had a great turnout, and the energy of getting together created what I can only describe as a buzz in the air.  On numerous occasions I saw faces light up as people recognized colleagues that they have only seen on zoom over the past few years. It’s just too bad that nobody stopped to capture any pictures because we were all so engrossed.

Then on the second and main day of the event, the full community gathered to share all the activity and updates from across the ecosystem. There was lots of great content, and at the end of this blog you’ll find links to presentations from the event (but sorry - no video recordings).

A highlight from me was hearing for the first time from Jio – India’s largest operator.  Jio has standardized on VOLTHA for their broadband deployments.  Check out the “Jio Whitebox OLT” called out in one of their slides:

DT has a VOLTHA community lab (shown) in Berlin Lab tours were offered during the event.

This meetup served as the kickoff for a number of upcoming activities. We’ll update everyone as we establish and launch the new Broadband Area Governing Board. This new board, working in collaboration with the project TSTs, will be aligning on and publishing a vision and roadmap for the area in the coming months. Stay tuned, this is poised to be a really exciting year for the ONF’s new Broadband Area.
