About ESnet

Our Mission

ESnet provides the high-bandwidth, reliable connections that link scientists at national laboratories, universities and other research institutions, enabling them to collaborate on some of the world's most important scientific challenges including energy, climate science, and the origins of the universe. Funded by the DOE Office of Science, and managed and operated by the ESnet team at Lawrence Berkeley National Laboratory, ESnet provides scientists with access to unique DOE research facilities and computing resources. 

As computational tools such as simulation and visualization become more fine-tuned and sophisticated, they also require the processing and management of greater amounts of data. The sheer volume of data generated by international scientific collaborations and the increasingly distributed nature of large data flows, as well as the development of real time cloud computing, is creating a staggering volume of network traffic. Since 1990, ESnet's average traffic has grown by a factor of 10 every 47 months. This growth trend is only accelerating as international scientific collaborations involving programs such as the Large Hadron Collider, climate research, and ITER, generate and exchange massive amounts of data. ESnet provides a scalable and efficient network infrastructure that enables scientists to optimize their resources and conduct ambitious, world-class research.

ESnet has a strong ethos of leadership in networking innovation. Our team is constantly improving the network and services to create a more versatile and robust network to serve the emerging needs of scientific researchers. We work closely with the international technical community to develop open source software and collaborative technical projects. Our programs, as well as our collaborations with other research and education networks around the world demonstrate our commitment to push network research forward so we will be able to anticipate and flawlessly serve the needs of DOE scientists.

Network Research and Development

ESnet is also pioneering network research and development programs, including:

  • OSCARS. The On Demand Secure Circuits and Reservation System software developed at ESnet, and now open-sourced to the community, creates multi-domain, virtual circuits guaranteeing end-to-end data transfer performance on the network.
  • perfSONAR. A test and measurement framework that provides end-to-end monitoring of multi-domain network performance. ESnet is a key member of the international perfSONAR collaboration.
  • 100G Testbed. The ESnet 100G testbed provides network researchers with a realistic environment for testing 100G application / middleware  experiments.
