Lawrence Berkeley National Laboratory

The Energy Sciences Network (ESnet) is the high-performance network user facility for the U.S. Department of Energy (DOE) Office of Science (SC) and delivers highly reliable data transport capabilities optimized for the requirements of data-intensive science. In essence, ESnet is the circulatory system that enables the DOE science mission by connecting all of its laboratories and facilities in the United States and abroad. ESnet is funded and stewarded by the Advanced Scientific Computing Research (ASCR) program and managed and operated by the Scientific Networking Division at Lawrence Berkeley National Laboratory (LBNL). ESnet is widely regarded as a global leader in the research and education networking community. ESnet interconnects DOE National Laboratories, User Facilities, and major experiments so that scientists can use remote instruments and computing resources as well as share data with collaborators, transfer large data sets, and access distributed data repositories. ESnet is specifically built to provide a range of network services tailored to meet the unique requirements of the DOE’s data-intensive science. Following the review held on May 8 and 9, 2019, between ESnet and NP, an interim review was held on September 2, 2020, to update the status of NP-supported scientific programs and facilities that were originally profiled. Preparation for this event included communication with key stakeholders (e.g., program and facility management, research groups, technology providers, and a number of external observers) to seek updates to the case studies that were prepared in 2019. Each group was asked to prepare a verbal or written briefing that updated the current, near-term, and long-term status, expectations, and processes supporting its science going forward.
