SUMMARY:SENSE in Practice: Quantifying the End-to-End Benefits of Intent-B
 ased Bandwidth Reservation for Exascale Science Workflows
DESCRIPTION:Inder Monga (ESnet; Lawrence Berkeley National Laboratory (LBN

 ence Berkeley National Laboratory (LBNL)); Aashay Arora and Diego Davila (

 and Cees De Laat (University of Amsterdam)\n\nThe escalating demands of sc
 ientific collaborations necessitate advanced networking for deterministic,
  secure, and orchestrated services across multiple administrative domains.
  The Software-Defined Network for End-to-end Networked Science at the Exas
 cale (SENSE) paradigm addresses these needs through intent-based networkin
 g and multi-domain orchestration. This paper evaluates SENSE's performance
  on a comprehensive multi-domain testbed, including GNA-G AutoGOLE, the Na
 tional Research Platform (NRP), FABRIC, and production LHC CMS infrastruct
 ure. Our results demonstrate that intent-based service requests are succes
 sfully translated into network configurations, with average provisioning t
 imes of 183 seconds for simple services and 290 seconds for complex multi-
 domain workflows. Performance monitoring confirms that SENSE maintains gua
 ranteed bandwidth allocations, enabling higher-priority data flows to comp
 lete significantly faster than in best-effort scenarios. This capability t
 ransforms the network into a first-class schedulable resource, optimizing 
 scientific workflows by prioritizing data criticality and moving beyond be
 st-effort limitations to achieve predictable and efficient data movement f
 or data-intensive scientific endeavors.\n\nRecording: Livestreamed, Record
