Science-Driven Network Requirements for ESnet


The Energy Sciences Network (ESnet) is the primary provider of network connectivity for the US Department of Energy Office of Science, the single largest supporter of basic research in the physical sciences in the United States. In support of the Office of Science programs, ESnet regularly updates and refreshes its understanding of the networking requirements of the instruments, facilities and scientists that it serves. This focus has helped ESnet to be a highly successful enabler of scientific discovery for over 20 years. In August, 2002 the DOE Office of Science organized a workshop to characterize the networking requirements for Office of Science programs. Networking and middleware requirements were solicited from a representative group of science programs. The workshop was summarized in two documents the workshop final report and a set of appendixes. This document updates the networking requirements for ESnet as put forward by the science programs listed in the 2002 workshop report. In addition, three new programs have been added. The information was gathered through interviews with knowledgeable scientists in each particular program or field.
