GÉANT is the pan-European data network for the research and education community. It interconnects national research and education networks (NRENs) across Europe, enabling collaboration on projects ranging from biological science to earth observation and arts & culture. The GÉANT project combines a high-bandwidth, high-capacity 50,000 km network with a growing range of services. These allow researchers to collaborate, working together wherever they are located. Services include identity and trust, multi-domain monitoring perfSONAR MDM, dynamic circuits and roaming via the eduroam service. Together with European NRENs, GÉANT connects 50 million users in over 10,000 institutions. Through links to research networks in other regions (such as Internet2 and ESnet in the USA, AfricaConnect in Africa, TEIN in Asia-Pacific and RedCLARA in Latin America), GÉANT enables collaboration between researchers in over half the world’s countries. Co-funded by the European Commission and Europe’s NRENs, the GÉANT network was built and is operated by DANTE. The GÉANT project is a collaboration between 41 partners: 38 European NRENs, DANTE, TERENA[10] and NORDUnet[11] (representing the five Nordic countries), and 30 Open Call project partners.
