ESnet and GÉANT upgrade European research network to 200Gbps

To ensure that data reaches scientists around the world quickly, the U.S. Department of Energy’s Energy Sciences Network (ESnet) and HUGE, a pan-European data network for the research and education community, recently teamed up to increase the capacity of ESnet’s network loop in Western Europe to 200 Gigabits per second (Gbps).

This enhanced network connects to ESnet’s 400 Gbps transatlantic network capacity, enabling researchers on both continents to collaborate at the speed of science.

Chris Cummings, a network engineer at ESnet said: “This upgrade to 200G is an important milestone for ESnet as it provides increased bandwidth, network reliability and flexibility at a time when the demands of high-energy physics experiments and other scientific instruments are rapidly increasing. increasing.’

Cummings also notes that this milestone will allow ESnet engineers to perform maintenance and upgrades with less overall impact on the network. This is especially important as ESnet will roll out its next-generation ESnet6 network architecture in Europe in 2023.

The ESnet and HUGE networks support researchers around the world by helping to deliver data and support collaboration between academic institutions. These networks support groundbreaking research projects such as the Large Hadron Collider (LHC), enabling the discovery of the Higgs boson. But the technology also supports future research such as the Hi-Luminosity LHC experiments will begin in 2027. As the complexity of these scientific challenges increases, so do data requirements and the need to share data with teams of researchers.

Kate Mace, Project Director of ESnet6 states: “ESnet6 increases the amount of data we can transfer across our network and then around the world. In its simplest terms, we are increasing the size of the “tubes” that carry the data to accommodate the growing data sets generated by scientific instruments and experiments around the world. That, and the need for innovative network technologies to route the data, is what drives Research & Education networks to upgrade.”

Tom Fryer of GÉANT, Head of International Relations, said: “The decades-old collaboration between global R&E networks such as ESnet and GÉANT is very valuable as we share the common goal of making science successful and supporting the needs of global research. This common goal will only become more important as scientific discoveries increasingly depend on global collaboration.’
