joint global effort was needed to coordinate the establishment of intercontinental connections, and this gave birth to Global Network Architecture (GNA), later on merged with the Global Lambda Integrated Facility (GLIF) into <a href=\"https:\/\/www.gna-g.net\/about-us\/\" target=\"_blank\" rel=\"noopener\">Global Network Advancement Group (GNA-G)<\/a>.<\/p><p>Around 2012, the time had come for the global R&amp;E Network community to join forces and define a common global architecture for the future R&amp;E network interconnect, a crucial aspect of the GREN.<\/p><p>By then, an innovative forefront of engineers in GLIF had successfully invented, tested, and produced numerous concepts for the R&amp;E infrastructure to enable the transfer of heavy data loads produced by new science facilities like the Large Hadron Collider (LHC), which in this case led to the LHC Optical Private Network (LHCOPN).<\/p><p>These concepts formed a solid foundation for the global NREN community facing their next challenge. Modern science desperately needed the ever-increasing supply of fast and resilient network bandwidth, not just within a country or region, but all over the planet. Hence, the Global Network Architecture movement was established to coordinate and integrate all the different network solutions, to ensure a consistent standard for the future GREN. NORDUnet was one of the instigators and, still today, contributes to further enhancing the intercontinental infrastructure for Research and Education. The major driver for this is that both science, research, and education, have become global endeavors, that require ubiquitous, fast, resilient, and cost-effective connectivity.<\/p><p><span
