9th and 10th October 2025

SIG-NGN is the Special Interest Group on Next Generation Networks.

The 15th SIG-NGN will take place on the 9th and 10th October 2025, co-located with the LHCOPN and LHCONE meeting at KIT in Karlsruhe, Germany.  This will be an in-person meeting over two half-days with possibility for remote participation.

Theme: Networking for AI and AI for Networking.

One half-day will be spent exploring how we build networks for new upcoming demands, such as ‘AI,’ and we hope to include presentations on Ultra Ethernet, beyond 1T (or even 10T) networking, and “ultra large networks.”  The second half day will be spent looking at how AI (or machine learning) can help us build and operate the networks.  In this we hope to have a couple of (suitably prepared) vendor presentations, plus community presentations on how the technology might enable troubleshooting and workflow management.
