 orkloads form an important class of scientific network traffic that by its
  nature (1) flows across different research infrastructure\, including rem
 ote instruments and supercomputer clusters\, (2) has ever-increasing throu
 ghput demands\, and (3) has ever-increasing integration demands—for exam
 ple\, observations at one instrument could trigger a reconfiguration of an
 other instrument.\n\nThis talk describes ongoing work on developing specia
 lized transport protocols for DAQ workloads. It introduces a new transport
  feature for this kind of elephant flow: multi-modality involves the netwo
 rk actively configuring the transport protocol to change how DAQ flows are
  processed across different underlying networks that connect scientific re
 search infrastructure. This idea takes advantage of programmable network h
 ardware that is increasingly being deployed in scientific research infrast
 ructure. The talk describes an initial evaluation through a pilot study on
  a hardware testbed and using data from a particle detector.\n\nBio: Nik S
 ultana is an assistant professor of Computer Science at Illinois Institute
 \nof Technology. He develops networking techniques to improve cybersecurit
 y and\nresearch infrastructure. Before joining Illinois Tech\, he was a po
 st-doc at\nUPenn after completing his PhD at Cambridge University. In 2024
  and 2023 he\nreceived VSP awards from the Universities Research Associati
 on\, and in 2022 he\nreceived a Google Research Award.\n
