About ESnet

A Platform for Accelerating Science Discovery

The Energy Sciences Network (ESnet) is a high-performance, unclassified network built to support scientific research. Funded by the U.S. Department of Energy’s Office of Science (SC) and stewarded by Lawrence Berkeley National Laboratory, ESnet provides advanced networking services to more than 50 DOE research sites, including the entire national laboratory system, its supercomputing facilities, and its major scientific instruments. ESnet also connects to more than 270 research and commercial networks, permitting DOE-funded scientists to collaborate quickly and productively with global partners.

ESnet's nationwide high-speed network connects scientists around the nation and the globe. »Download the most recent ESnet network map.

A Robust Network for Next-Gen Science

Spurred by the growth of large international collaborations in high energy physics, climate science, and genomics, the research community’s needs to manage and transfer large quantities of data are exploding in scope and complexity. Currently, ESnet carries around 20 petabytes of data monthly. Every four years, ESnet's average network traffic increases by a factor of 10. This growth is propelled by the rising tide of data produced by more powerful supercomputers, global collaborations that can involve thousands of researchers, and specialized facilities like the Large Hadron Collider and digital sky surveys.

ESnet6, the most recent generation network, features multiple 100-400Gbps optical channels for over 46 Terabits-per-second of bandwidth and intelligent network services to support the unique data-intensive needs of scientific research.
