About this network

GARR is Italy's National Research and Education Network (NREN) — the high-speed backbone connecting the country's universities, research institutes, libraries, and cultural institutions.

What it's used for

• Interconnecting Italian academic and research sites and linking them to the pan-European research network GÉANT and the global R&E community.
• Carrying data-intensive science traffic (physics, genomics, supercomputing) that would swamp a commercial consumer ISP.

Notable

• Like Internet2 (US), JANET (UK), or DFN (Germany), GARR is a non-commercial network funded to serve education and research, not the general public.
• Operates its own dark-fibre footprint across Italy.

Interesting

• NRENs such as GARR were among the earliest high-bandwidth networks and often pilot next-generation networking years before commercial ISPs adopt it.
