KREONET International Network
Overview
In 2005, the Global Ring Network for Advanced Applications Development (GLORIAD) project was initiated to enable global collaborative research in large-scale scientific fields such as high-energy physics, astronomy and space science, climate science, and nuclear fusion. With the participation of research networks from 15 countries—including the United States, China, Russia, Canada, and the Netherlands—the project established 10 Gbps interconnections worldwide.
* GLORIAD: Global Ring Network for Advanced Applications Development
Since 2023, the KREONet2, KREONET International Network, has evolved into a global 100 Gbps ring, connecting (Amsterdam) - Asia (Singapore, Hong Kong) - South Korea (Daejeon) - North America (Chicago, Seattle) - Europe (Amsterdam), providing an essential backbone for global scientific research collaboration.
Infrastructure
- 100 Gbps international backbone circuits: Hong Kong – Daejeon, Singapore – Daejeon, Daejeon – Chicago, Daejeon – Seattle, Chicago – Amsterdam, Amsterdam – Singapore
- 6 International Points of Presence (PoP): Singapore, Hong Kong (China), Daejeon (Korea), Chicago and Seattle (USA), Amsterdam (Netherlands)
* The infrastructure is composed of optical transport equipment, high-performance switches and routers, and performance measurement servers.
