High-Capacity Users

This chord diagram depicts the volume of data moved across ESnet in calendar 2022 between the top 40 pairs of source and destination organizations. Of Fermi National Accelerator Laboratory’s 199 petabytes sent, 128 PB were associated with the Large Hadron Collider project. Additionally, the 73.5 PB of data moved from University of Chicago to Indiana GigaPOP was entirely attributed to the LHC.

Usage by National Laboratories

This diagram depicts the volume of data moved across ESnet in calendar 2022 between the top 40 pairs of national laboratories. Argonne National Laboratory was the largest producer and consumer of inter-lab data, with a combined 34 petabytes of data movement to and from other labs. Of this, 14 PB of data was sent to Oak Ridge National Laboratory, and 7.65 PB was received from Lawrence Livermore National Laboratory as part of an ESGF Data Replication Effort.

Evolution of ESnet

ESnet Traffic: Historic Usage

ESnet’s network traffic has grown exponentially in the past two decades. In 2022, ESnet carried more than 1.3
exabytes of data to and from the sites it connects. An exabyte is a nearly incomprehensible amount of data, equal to
1,000 petabytes or one billion gigabytes. This torrent of data is spurring ESnet to innovate in multiple areas to
continue to deliver on its mission — and enable DOE scientists to seamlessly move, store, and analyze that data
without drowning in it.
