  • Lessons from APAN61 in Dhaka

    Lessons from APAN61 in Dhaka

    Last week, Alexander and I traveled to Dhaka, Bangladesh, for APAN61 (APAN stands for Asia-Pacific Advanced Network). These types of conferences are often viewed from a technical standards and backbone capacity perspective, but our time in Dhaka proved that the most critical infrastructure we build isn’t made of fiber—it’s made of people.

    A Federated Foundation for Global Science

    I was invited by APAN to deliver a keynote titled “Staying Connected: A Federated, Open Foundation for Global Research & Education Collaboration.” Giving a keynote was exciting for me – in a good way – and a personal milestone. But the real value lay in the message: how we, as a global community, can ensure that research and education aren’t siloed by geography, geopolitics, or other obstacles. For that purpose, addressing both the why and the how of the need for a federated global infrastructure. And it was a reminder that our work within NRENs (both at SURF and abroad) feeds into a much larger, global engine of collaboration and progress for Science & Education. 

    Besides the keynote, I also gave an additional presentation representing SURF in a Special Interest Group (SIG) on Science Engagement. At SURF, we often talk about science engagement and how to improve our efforts in that respect but seeing it in practice and discussing with other NRENs how they do it during APAN was very stimulating and useful. 

    Specific Takeaways from the Field

    Beyond the podium, four specific observations stood out to me:

    • Infrastructure in Practice: The Bangladesh Research & Education Network (BdREN) has successfully implemented eduroam in all national airports. Coming from the Netherlands, seeing this level of user-focused service in action was impressive. It’s a standard of accessibility we should all be aiming for. Schiphol & Nationale Spoorwegen, bring it on! 
    • High-Level Science Engagement: I spent time with researchers in oncology and molecular biology. The sophistication of their work is a clear signal: they are driving serious scientific inquiry that requires the kind of international research network connectivity we provide. 
    • Logistical Excellence: Organizing a conference of this scale in a city as complex as Dhaka—a metropolis of over 25 million people—is a massive undertaking. To put it in perspective: the population density there is nearly ten times that of Amsterdam. Moving dozens of international guests through that kind of environment requires serious planning. The hospitality and flawless execution by the BdREN team really showcased the professionalism and dedication of our partner NRENs in the region.
    • The “8th Layer” of the OSI Model: Some of you know that when it comes to networking, I’m a Layer 0-3 kinda girl—they don’t call me the “Dark Fiber Lady” for nothing —but this week was all about the human 8th layer. Whether it was reconnecting with old friends & partners, establishing new partnerships & perspectives on future collaboration, or learning about local history like the Shaheed Minar, these face-to-face meetings are what make the global R&E collaboration possible.

    Looking Ahead

    Collaborating with the Asia-Pacific region isn’t just a “nice-to-have” for SURF; it is essential for a functional and resilient global research ecosystem. We’re bringing back more than just notes—we’re bringing back renewed partnerships, connectivity to enable global research opportunities for our SURF members, and a fresh perspective on what it means to be a partner in this international community.

    A special thanks to Mohammad Tawrit and the entire BdREN team for their hospitality and for showing us the future of R&E in Asia.

  • Highlights from Internet2 TechEx 2025

    Highlights from Internet2 TechEx 2025

    At Internet2 TechEx 2025, global developments in research and education (R&E) network infrastructure were high on the agenda. In a well-attended update, Brenna Meade (International Networks, Indiana University) shared an overview of key steps being taken worldwide to scale capacity, resilience, and automation in federated network services.

    Major capacity upgrades, including transoceanic links

    Meade outlined a broad range of ongoing and planned upgrades across international backbone and exchange infrastructures. This included new 400 Gbps transoceanic links—critical for data-intensive research and collaboration across continents. She also highlighted activity and continued evolution across multiple Global Exchange Points (GXPs), including FUJI-XP, SOE, GOREX, MANLAN, MOXY, NetherLight, and Pacific Wave. Together, these hubs form an important foundation for high-performance global connectivity between R&E networks.

    NSI reaches production readiness

    A key milestone highlighted in the session: NSI (Network Service Interface) has reached production readiness. NSI enables interoperable, automated service provisioning across network domains. In practice, this supports standardized ways for organizations and networks to request, set up, and manage end-to-end services across multiple administrative boundaries.

    For NRENs, this aligns closely with the push toward scalable, federated connectivity: less manual coordination, faster delivery of services, and more reusable interfaces and operational agreements between domains. Reaching production readiness is therefore a concrete step toward more automated and dependable international network service ecosystems.

    Technology—and the community behind it

    Beyond the technical program, TechEx continues to stand out as a strong community meeting point. Informal conversations between sessions, sharing experiences across very different operating contexts, and social traditions such as the 5K fun run all reinforce the trust and relationships that are essential to building and operating resilient infrastructure.

    In summary: TechEx 2025 underscored how global R&E networks are moving forward on both capacity and automation—with NSI marking a notable step toward interoperable, federated service delivery.

  • SURF at the 6th Global Research Platform: Building the Future of International Research Networking

    SURF at the 6th Global Research Platform: Building the Future of International Research Networking

    Chicago, September – At the 6th Global Research Platform (GRP), SURF joined peers from around the world to share progress, exchange insights, and strengthen collaboration in global research networking.

    In my presentation, I highlighted SURF’s next steps:

    • Updates on SURFnet Infinity and NetherLight
    • Terabit trials with CERN and the LUMI supercomputer
    • Explorations in quantum-secure networking and fiber sensing

    A recurring theme at GRP was the importance of the federated approach: each NREN serves its own members, but together we form a global infrastructure that supports research at scale. This balance of local autonomy and international collaboration is vital to the community’s success.

    Many thanks to Joe Mambretti, Maxine Brown, and the GRP community for fostering an open, collaborative environment. SURF looks forward to continuing this work and helping shape the future of international research & education networking.

  • Celebrating 20 Years of LHCOPN & Looking Ahead to the Future of Scientific Data Infrastructure

    Celebrating 20 Years of LHCOPN & Looking Ahead to the Future of Scientific Data Infrastructure

    This week in Manchester, SURF participated in the 54th LHCOPN-LHCONE meeting, where global experts gathered to discuss the evolution of research networking. It was a special occasion as we celebrated 20 years since the first LHCOPN meeting, reflecting on how far we’ve come in enabling high-speed data transfer from CERN’s Large Hadron Collider (LHC) to researchers worldwide.

    At the heart of it all, we organize IT infrastructure to make science happen—to help researchers probe the fundamental nature of the universe. Whether it’s LHC physicists searching for the building blocks of matter or SKA astronomers listening to the faintest signals from the early universe, both fields generate massive amounts of data that push the limits of computing and networking.

    Sessions on LHC’s evolving network infrastructure highlighted valuable lessons as we discuss how to develop the SKA Observatory’s data systems. While the scale and patterns of data movement may differ, exploring synergies between NREN-based networks for LHC and SKA was particularly insightful.

    Of course, no meeting is complete without spirited debates—this time on the broader challenges of expanding network capabilities for large-scale scientific projects. The conversation naturally raised questions of trust, Acceptable Use Policies (AUP), and the impact on existing communities. The balance between openness and security, integration and specialization, is a fine one. And as history has shown, discussions on centralized vs. federated models tend to resurface over time—sometimes wrapped in new proposals, sometimes in a familiar shade of red.

    As always in these meetings, technical discussions mixed with broader questions of policy, trust, and governance—some unfolding over structured sessions, others in those classic last-minute deep dives when time was running short. Because in research networking, the big questions are never just about technology.

    Grateful for the engaging discussions, the shared knowledge, and the beautiful opening trip down memory lane. Plenty to reflect on and even more to explore—let’s keep the momentum going!
