Monday 8th April - Tuesday 9th April 2024

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

This meeting of the 14th meeting of the SIG will be held as Hybrid Meeting in Catania IT.


Following a fruitful co-location of meetings in Prague in April 2023, SIG-NGN and the LHC networking group will once again co-locate face-to-face meetings this coming spring. This time we are adding networking for the Square Kilometre Array to the mix.

The 14th SIG-NGN will take place on 8-9 April 2024 at INFN in Catania, Sicily, Italy. The agenda will be finished over the coming weeks, and will focus on technologies for sharing of existing physical networks (overlays, underlays, spectrum sharing) and how they enable mission-specific network services, as well as on network architecture for intercontinental connectivity, including policies and technologies for links sharing as well as the evolution of  intercontinental R&E connectivity.

As the meeting is co-located with LHC and SKA, the SIG-NGN meeting topics will be framed for enabling networking for large, global science communities.

SIG-NGN will be held over two half days - afternoon of April 8 and morning of April 9 - followed by two days on networking for SKA and LHC. Mark your calendar now; we hope to see you in Catania for 4 exciting days on research networking.

Transportation to and from the venue

Bus: ask for BRT1 bus in via Etnea: from the venue  BRT1 is aimed to Piazza Stesicoro in Via Etnea, where it turns to go back to our venue. You have to get out at the stop Cittadella Universitaria Ovest. To go back in Via Etnea you have to go to bus stop Cittadella Est. Tickets cost 1.00 euro each, and they are sell in several places in Via Etnea.

Metro: near piazza Stesicoro you can find a metro station. You have to stop at stazione Milo, where you can catch a shuttle going to Cittadella Universitaria. Going to the venue, the metro shuttle stops at the same stop than BRT1, Cittadella Unversitaria Ovest. To go back there is a metro shuttle stop 50 meteres away from the venue to go at Stazione Milo, where you can catch the metro to Stazione Stesicoro. At the metro stations there are ticketing machines; tickets cost 1.00 euro each.
the distance from piazza Stesicoro to the venue is about 3.5 km, slightly uphill (DFA is about 150 metres high)
