Monday 12th September 2022

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

The 9th meeting of the SIG will be held hybrid, face-to-face location in Reykjavik, Iceland - Harpa, Austurbakka 2, 101 Reykjavik, Iceland - co-located with the NORDUnet Conference 2022. If you want to participate to the conference please register directly on their website and if you would only like to join the SIG-NGN meeting then you don't need to register extra for the conference.

"How do we handle the next leap in traffic level?"

With a full-day meeting, we will focus on presentations and discussion on future network architectures that R&E networking will need to manage the next leap in capacity requirements from next-generation Research Infrastructures (HL-LHC, SKA, LSST, and more). We will address technologies such as spectrum sharing, underlay and overlay networking, L2 packet inspection, P4, and more, and discuss ideas for how these technologies can be used by R&E networks to do traffic engineering, capacity management, and support for demanding research applications.
