[GREN Map WG] November Meeting Highlights & Holiday Schedule
by Gustavo Hermínio de Araújo 04 Dec '25

04 Dec '25

Hello everyone, Better late than never! I am writing to share a summary of what was discussed during our GREN Map WG meeting in November. Please find the detailed meeting notes attached to this email. In the attached slides, you will find screenshots and details of two Proof of Concepts (PoCs) we have been working on: * Global Network Advancement Group (GNA-G) Projects: We are replicating the map currently found on the GNA-G website, featuring international connection projects (e.g., AmLight, APOnet, BELLA, etc.) within our dynamic environment. * Reference Source: GNA-G Static Map<https://www.gna-g.net/wp-content/uploads/2024/12/GNA-G-Projects-Global-Map-…> * NRENs Map: A consolidated view of multiple NREN topologies in a single visualization. * Reference Source: GÉANT Compendium Map<https://compendium.geant.org/network-map> [cid:4470cfb6-f564-412c-9c21-f3feee8efa06] We also presented upcoming automation features for collecting and anonymizing data from Netbox to GRENML, which will be published soon. GRENML Repository Launch I am pleased to announce our GRENML repository, which currently hosts topologies for several NRENs. For this initial version ("Version 0"), we utilized data available via the GÉANT Compendium. We invite you to explore it here: https://github.com/grenmap/GRENML-Repository Holiday Schedule Due to agenda conflicts and the holiday season, we will not hold meetings in December or January. We will resume our activities in February 2026. I wish you all a Merry Christmas and a Happy New Year!

Draft Guidelines for WG Topology Data Sharing
by Gustavo Hermínio de Araújo 13 Nov '25

13 Nov '25

Dear Working Group Members, I am writing to request your consultation on the draft "Guidelines for Topology Data Sharing" for our Working Group. The objective is to establish a clear framework for sharing data in a manner that is both secure and effective. We have formulated an initial draft comprising five key principles regarding security and privacy. We would like to consult the group on whether these five items are sufficient for our purposes, or if you would like to add further points. We welcome any feedback on whether these guidelines are comprehensive and clear. Draft Guidelines: 1. Data provided will be public. Do not include any data that should not be public. 2. The geo-position of infrastructure (PoPs, equipment) should be obfuscated. 3. Due to DDoS security concerns, carefully consider if you want to provide link capacity values for core infrastructure. 4. It is not recommended to include capacity on links to end nodes / institutions (due to DDoS security concerns). 5. Consider whether infrastructure details are necessary e.g. multiple routers/switches in one location should be consolidated to a single generic node. Infrastructure details should not include equipment type or vendor name. Following this review period, the guide will be consolidated into a formal document, and I will share the link to the doc once it is finalized. We appreciate your attention to this matter. Sincerely, --- Gustavo Araújo |Coordenador de P&D | R&D Coordinator Gerência de P&D em Ciberinfraestrutura (GCI) | Cyberinfrastructure R&D Management Tel.: +55 61 9 8379-7918 | Teams: gustavo.araujo(a)rnp.br<mailto:gustavo.araujo@rnp.br> www.rnp.br<http://www.rnp.br> [cid:b3d4e361-3285-44fe-9ec1-36ce799564c7]
