seeking a potential connection between the mapping effort and RE Topology Report
by Steven Wallace 19 May '26

19 May '26

Greetings, Internet2 and CAIDA are developing a tool to visualize the AS-level topology of the global R&E ecosystem. The tool currently uses pre-policy routing data from Internet2, and we hope to expand it to incorporate pre-policy data from additional R&E networks. We would like to explore how this AS-level topology work might connect with the physical topology mapping being developed by the working group. Brenna Meade and I will be presenting these tools at TNC26. We are also hosting the BoF “Coordinating BGP Policy and Tooling Across the Global R&E Infrastructure” on Thursday from 9:00–10:30 a.m. For working group members attending TNC26, we would welcome the opportunity to discuss how these two efforts might complement one another. We would also like to arrange a time to demonstrate the tool to the working group and get your input. Here are a few links that demonstrate how the tool depicts AS topology for different networks: SURFnet: https://rootbeer.internet2.edu/re-topology-report/#asn=1103&also=112%2C288%… NORDUnet https://rootbeer.internet2.edu/re-topology-report/#asn=2603&also=224%2C239%… University of Hawaii: https://rootbeer.internet2.edu/re-topology-report/#asn=6360&also=3477%2C165… KISTI https://rootbeer.internet2.edu/re-topology-report/#asn=17579&also=1237%2C16… Looking forward to the discussion, steve Steven Wallace Director - Routing Integrity Internet2 ssw(a)internet2.edu Steven Wallace Director - Routing Integrity Internet2 ssw(a)internet2.edu

GNA-G GREN Map Working Group
by Gustavo Hermínio de Araújo 18 May '26

18 May '26

Dear all, I would like to invite you to a pre-TNC GREN Map meeting in June 2026. The meeting will take place at 14:00 UTC (11:00 AM GMT-3). In this meeting, we would like to discuss: * How should we consistently represent the different types of networks and initiatives in our ecosystem? * A sneak peek of our new visualization. Looking forward to seeing you there!

[GREN Map] Request for feedback on GREN Map classification approach and TNC26 preparation
by Lucas Bondan 14 May '26

14 May '26

Hi everyone, Over the past weeks, we’ve been advancing the GREN Map and preparing a demo for TNC26. As the map evolves, one question keeps coming up and we’d really value your input: how should we consistently represent the different types of networks and initiatives in our ecosystem? While working on the current version, we’ve identified some challenges, for example: - How to distinguish between NRENs, regional backbones, and intercontinental connectivity initiatives; - How to better represent initiatives/systems/consortiums like AmLight or BELLA without “breaking” the map structure; - How to reflect the relationships between national, regional, and global infrastructures. As a starting point, we are exploring a simple classification such as: - NRENs (e.g., RNP, GARR, etc.); - Regional/backbone networks (e.g., GÉANT); - Intercontinental connectivity initiatives (e.g., RedCLARA?); - Consortia/projects (e.g., BELLA, AmLight). But this is still work in progress and likely incomplete, that's why we would really appreciate your thoughts: - Does this classification make sense? - What are we missing? - How would you represent initiatives that don’t neatly fit into one category? To help move this forward, we are considering a call in early June (around June 4) to discuss this topic and also share what we are planning to present at TNC26. If you have quick thoughts, feel free to reply directly to this thread. Even brief comments would already be very helpful. Looking forward to your feedback. Best regards, -- Lucas Bondan, Ph.D. R&D Coordinator - RNP<https://www.rnp.br/> Invited Researcher - UnB<https://unb.br/> lbondan.wordpress.com<http://lbondan.wordpress.com>
