GN4-3N – the next generation of the GÉANT network – network.geant.org
In response to the H2020 call H2020-SGA-INFRA-GEANT-2018 Topic , GÉANT is proposing the most significant refresh of the GÉANT network in a decade, with a major project designed to support the needs of Europe's research and education community for the next 15 years.
The GN4 Phase 3 Network (GN4-3N) project will involve restructuring the GÉANT backbone network through exploration and procurement of long-term Indefeasible Rights of Use (IRUs), leased lines and associated equipment, serving the GÉANT partner NRENs and providing interconnectivity to the global research and education community.
A market study was undertaken on availability and pricing for connections that are either fibre, spectrum on fibre, or (multiple) 100 Gbps connections, and the proposed work will substantially increase the number of fibre-connected countries to provide a more-level network experience for all partners. This will also enable higher minimum-capacity thresholds, ease of access to clouds and other services, and the highest levels of security.
Building the network based on long-term
fibre leases creates a stable,
yet flexible, infrastructure
Building the network based on long-term fibre leases creates a stable, yet flexible, infrastructure. The Open Line System provides a similarly stable layer on top of that infrastructure so that the technological evolutions in transponder technology can be easily and affordably integrated. This creates a more future-proof environment.
Through this proposed work, the GÉANT Association, together with its National Research and Education Network (NREN) partners will provide future-proof capacity and enhanced service capability to support the planned and anticipated growth in demand across Europe.
