Description

This is a weekly Thursday meeting, except for the third Thursday of the month, and provides a venue to discuss network monitoring, measurement, analytics, alerting and alarming for OSG-LHC, NRP, OSG-PATh, IRIS-HEP and others interested in the topics being discussed.

Our agendas and meeting notes are available in this Google Folder  (Please request edit access if you need it)

We use Zoom https://umich.zoom.us/j/99139520450?pwd=RmlrYjhLdTlCRkdQUGFTY0J5OG9xUT09

        • a) Multi-modal Transport for Integrated Research Infrastructure

          Data Acquisition (DAQ) workloads form an important class of scientific network traffic that by its nature (1) flows across different research infrastructure, including remote instruments and supercomputer clusters, (2) has ever-increasing throughput demands, and (3) has ever-increasing integration demands—for example, observations at one instrument could trigger a reconfiguration of another instrument.

          This talk describes ongoing work on developing specialized transport protocols for DAQ workloads. It introduces a new transport feature for this kind of elephant flow: multi-modality involves the network actively configuring the transport protocol to change how DAQ flows are processed across different underlying networks that connect scientific
          research infrastructure. This idea takes advantage of programmable network hardware that is increasingly being deployed in scientific research infrastructure. The talk describes an initial evaluation through a pilot study on a hardware testbed and using data from a particle detector.
