Network Requirements Gathering
Network Requirements for Science
The Energy Sciences Network (ESnet) is a facility of the Department of Energy's Office of Science (DOE SC) and provides network connectivity and services for DOE SC Labs to communicate with science collaborators around the world. ESnet also provides networking for the Labs and sites of other DOE offices. To support this mission, ESnet regularly collects requirements from a variety of sources, including network observation and monitoring, the National Laboratory Chief Information Officers (CIOs) and DOE SC program managers, and by directly interacting with the scientists that use the network.
ESnet routinely monitors the volume and aggregate characteristics of the traffic traversing the network. This provides ESnet staff with historical usage information and allows us to make predictions based on past trends. Some examples of the network observation data used by ESnet are linked below:
Laboratory CIOs and Program Managers
ESnet receives input from the CIOs of the DOE National Laboratories, as well as from program managers in the DOE Office of Science. These interactions provide ESnet with high-level direction as to the business needs of the Laboratories and the strategic needs of the program offices.
ESnet collects network requirements from ESnet sites through meetings with site representatives at the ESnet Site Coordinators Committee (ESCC). ESnet Site Coordinators are encouraged to collect requirements from their instruments, facilities and key staff (such as principal investigators on large projects), especially when the requirements come from work that is not funded by DOE SC.
Users, Scientists, and Program Requirements Reviews
ESnet conducts regular program requirements reviews to determine the current and future science networking requirements for each of the six DOE SC program offices. The reviews elicit information from program managers and key scientists about the current and future network requirements of the science conducted by the particular program office. Each review has a final report, which is published on the ESnet web site.
More information on the reviews is available on the ESnet Network Requirements Reviews page. There is also a FAQ page to assist case study authors when preparing case studies for requirements reviews.
DOE Office of Science - Network Requirements for Science Programs ESnet conducts bi-annual network requirements reviews to determine the current and future science networking requirements for the six DOE Office of Science program offices. The purpose of these reviews is to accurately characterize the near-term, medium-term and long-term network requirements of the science conducted by each… Read More
ESnet regularly collaborates with multiple organizations and entities outside of the DOE complex for the purpose of supporting science and research on a global scale. Gathering network requirements from researchers at universities and collaborating organizations around the world is key to building and supporting the infrastructure researchers rely upon to advance their rates of discovery. Just as… Read More
General Questions Why does ESnet collect networking requirements? ESnet collects networking requirements from its constituents to facilitate planning for capacity, technology and services. Given that the funding and construction cycles for upgrades to national network infrastructure can amount to several years, we must plan for changes several years in advance. Who does ESnet ask… Read More
