Ultra-high-speed national and research networks (NRENs) in over 100 countries connect thousands of universities, schools, GLAMs and research institutions around the world.
It's like the internet you know, but purpose-built for research and education. It allows researchers worldwide to connect and collaborate on urgent issues like climate change, food security and global pandemics.
This powerful web of nation-to-nation connectivity, collectively, is the Global Research and Education Network (GREN). Australia is connected to the GREN though AARNet, Australia's national research and education network.
