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:
