What R&E networks are doing for Big Science?

The session will discuss the services and infrastructure provided by R&E networks, how they support big science users and their needs of large data transfers, and future plans of R&E Networks.

Big science user requirements I

This session will discuss the network capacity requirements of big science users and how these requirements are evolving as scientific research becomes increasingly data-intensive.

Host: Edoardo Martelli (CERN)

• 07_SKA - Rosie Bolton (SKA) '25

The SKA Observatory and the SKA Regional Centres: Operational model and implications for data transfer.

• 08_ITER - Peter Kroul (ITER) '25

• 09_HL-LHC dataflows: An experiment view - Mario Lassnig (CERN)'25

The LHC experiments are facing a ten-fold increase in throughput requirements for the High-Luminosity upgrade. In addition, the
complexity of dataflows is ever evolving, pushing the boundaries of our infrastructure. In this talk, we highlight important use cases shared by the LHC experiments, and delve deeper into the specific needs of the ATLAS Experiment.

• 10_Computing Models for Processing Streaming Data from DOE Science - Graham Heyes (Jefferson Lab) '25

Graham Heyes is the head of the Scientific Computing Department at Jefferson Lab. He was also the lead of the laboratory’s Data Acquisition Support Group. His current research interest is streaming data acquisition and analysis. This talk will explore what that is, and computing models, both hardware and software, that are appropriate for streaming data.

• 11_Integrated Research Infrastructure - A DOE ASCR Initiative to
  Accelerate Science -  Chin Guok (ESnet) '25

DOE ASCR has been championing the Integrate Research Infrastructure initiative, which is to enable highly coordinated, collaborative research and integrating capabilities across DOE’s
world-leading facilities.  This initiative has the potential to drive DOE's funding and direction in the next decade.

Mapping big science requirements to what the R&E Networks are doing

This session will include presentations on the requirements of big science users and how these requirements can be mapped to the services and infrastructure provided by research and education (R&E) networks

Host: Edoardo Martelli (CERN)

• 14_ESCAPE: ‘Large science experiments and networking futures’ - Yan Grange (ASTRON / LOFAR)'20
  Yan will present the work that has been executed on the Scientific Data Lake, a data infrastructure targeted at large-scale data management within a network of heterogeneous storage resources. This work was conducted as part of work package 2 of the ESCAPE project.
