Overview
The Energy Sciences Network (ESnet) is a facility of the DOE Office of Science (SC) whose mission is to enable those aspects of the DOE/SC mission that depend on wide area networking for success. To this end ESnet provides network connectivity and services for DOE/SC Labs to ensure that the labs have robust communication with all of their science collaborators world-wide. ESnet also provides networking for the Labs and sites of other DOE offices.

In support of ESnet's mission, ESnet regularly collects requirements from a variety of sources, including network observation and monitoring, the National Laboratory CIOs and DOE/SC program managers, and through direct interaction with the scientists that use the network.

Network Observation
ESnet routinely monitors the volume and aggregate characteristics of the traffic traversing the network. This provides us with historical information and allows us to make predictions based on past trends.

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 other needs of the program offices.

Users, Scientists, and Program Office Workshops
ESnet conducts regular network requirements workshops for each of the six DOE/SC program offices. The workshops elicit information from program managers and key scientists about the current and future network requirements of the science conducted by the particular program office. More information on the workshops is available on the network requirements workshop page. There is also a FAQ page to assist case study authors.

ESnet Sites
ESnet collects network requirements from ESnet sites through meetings with site representatives at the ESnet Coordinating Committee (ESCC) meetings. 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.
