What is GN4-3N?

GÉANT Intercontinental Connectivity map

The GN4 Phase 3 Network project (GN4-3N) is the most significant refresh of the GÉANT network in a decade, aimed at supporting the rapidly growing needs of Europe's research and education community for the next 15 years.

Making the most of new technologies, and opportunities presented by a changing landscape of network procurement, GN4-3N will provide improved performance, increased flexibility, and reduced expense alongside long-term platform stability.

It will enable fairly priced, high-capacity connectivity across all of Europe, where a gigabit of capacity will cost virtually the same across the network and in turn bring consistent and predictable pricing for the benefit of NRENs and their customers.

GN4-3N is therefore not ‘just’ a network project: it is helping to narrow the digital divide, stimulating the market in cross-border communications, and supporting greener ICT.

And with an average annualised increase in network traffic of 30% per annum for each of the past five years, it is essential to our NREN partners and their research and education communities.
