NP Requirements Review 2023

Quick Links


The primary purpose of an ESnet Requirements Review is to discuss and analyze current and planned science use cases and anticipated data output of a particular program, user facility, or project to inform ESnet’s strategic planning, including network operations, capacity upgrades, and other service investments. The goal of this particular review is to accurately characterize the networking requirements of science funded by the NP Program Office. These requirements will serve as input to the ESnet architecture and planning processes, and will help ensure that ESnet continues to provide world-class support for scientific discovery for DOE scientists and their collaborators. The tangible outcome of the review will be a document that includes both the network requirements and a supporting narrative. 

The Requirements Review is an in-person event. By design a highly conversational process through which all participants gain shared insight into the salient data management challenges of the subject program/facility/project. The ESnet Science Engagement Team organizes, convenes, and executes the Review in close coordination with the ESnet Program Manager and one or more leads from the subject program/project/facility.

ESnet will focus the Review to deliver the following outcomes:

  • Identification and analysis of any data management gaps and/or network bottlenecks that are barriers to achieving the scientific goals.
  • A forecast of capacity/bandwidth needs by area of science, particularly in geographic regions where data production/consumption is anticipated to increase or decrease. 
  • Development of a shared understanding of the data management needs, challenges, and capability gaps that could inform strategic investments in solutions.

Review Objectives, Outcomes, and Artifacts

  • Through a cases study methodology, the Review provides ESnet with information about:
  • Existing and planned data intensive science experiments and/or user facilities, including the geographical locations of experimental site(s), computing resource(s), data storage, and research collaborator(s). 
  • For each experiment/facility project, a description of the “process of science,” including the goals of the project, how experiments are performed and/or how the facility is used. This description includes information on the systems and tools used to analyze, transfer, and store the data that is produced. 
  • Current and anticipated data output on near and long term time scales.
  • Timeline(s) for building, operating, and decommissioning of experiments, to the degree these are known.

  • Existing and planned network resources, usage, “pain points” or bottlenecks in transferring or productively using data the science produces.


The review will be a 2-day event. This includes all day Tuesday, Oct 31st 2023 and Wednesday Nov 1st 2023.  Please plan travel to coincide with the expected event times.

Review Registration

The review is by invitation only. Please RSVP by emailing Jason Zurawski ( zurawski @  es . net ).  If you require a hotel reservation, please follow the hotel registration link below:

Review Report

This review will generate a network requirements document for the NP Program Office. This document will be composed of the network requirements input from the workshop attendees.

Review attendees should review the case study template document and other background materials on the documents page. Please also review the pages on the ESnet public web site. Please then use the background materials in combination with your own knowledge and experience, as well as input from representatives from your facility and laboratory, to generate a narrative describing your scientific research, instrument, facility or other scientific endeavor. Examples of science narratives with their accompanying requirements matrices can be found in the reports from previous reviews. Case studies (both the narrative and the corresponding data table) must be submitted to the review organizers (Jason Zurawski ( zurawski @ ), Eli Dart ( dart @ es . net ), Andrew Wiedlea ( awiedlea @ es . net ), Ken Miller (ken @ es . net), & Nathan Miller ( nmiller @ es . net)) by Friday October 13, 2023.

At the review we will review the documents and speak with the attendees to ensure that we understand the science being done insofar as it has an impact on networking. We will also make sure that we capture the timelines for upgrades, new facilities, changing collaborations, and other coming events that will change the way in which the network is used.

The review format is much closer to a round-table discussion rather than a series of PowerPoint presentations. If you feel that you really need to give a formal presentation we can accommodate that by providing a suggested template, but we have found that these review are more productive if there is a simple discussion and exchange of ideas rather than a formal presentation format.


The review will be held at the following hotel:

Hilton Washington DC/Rockville Hotel & Executive Meeting Ctr
1750 Rockville Pike,
Rockville, MD 20852-1699

A block of rooms has been reserved for review participants using this link:

The rate is $193 USD per night, this rate is still below the government per-diem for the region and time of year.  The hotel cut-off is currently 11:59pm on October 9th. Please make your room reservation as soon as possible.  Whether you are a local or traveling attendee it is imperative that you email Jason Zurawski ( zurawski @  es . net ).


The hotel has parking for guests and day-visitors.  Check in with the meeting organizers when you arrive and note you parked.  

Airport Info

There are two airports in Washington DC area, both are ~30miles from the venue:

  • Ronald Reagan Washington National Airport (DCA)
  • Washington Dulles International Airport (IAD)

Ground Transportation

The hotel does not offer shuttle service.  You can reach the venue using methods such as local taxis, and Lyfts/Ubers.

The hotel is < 0.5 mile from the Twinbrook stop on the WMATA's Red Line. WMATA directly serves DCA airport (Blue/Yellow line, Transfer to Red Line), and is an option from IAD airport (Silver Line, transfer to Red Line).

Please let us know if you have any questions about travel logistics - we look forward to seeing you all at the event.
