Description
Given the increased amount of data expected during the HL-LHC and the escalation of data transfers that this implies, it becomes of paramount importance to have control over the available network bandwidth and the ability to allocate this bandwidth for high-priority and time sensitive data flows.
The Rucio/SENSE integration project intends to provide Rucio with Software Defined Networking capabilities to create bandwidth guaranteed network circuits on-demand for desired data flows. CMS has been the initial use case focus and this has now expanded to the ATLAS workflow. In this work we talked about the experience of the first two ATLAS sites that have joined this effort. Having different security constraints, on each of them, we have adopted different approaches on these two deployments. On NET2/UMass we have full access to their network infrastructure which has allowed us to experiment with different configurations and focus on maximizing throughput. On the other hand, in UChicago we have faced a more restrictive scenario with no network access, hence giving us the opportunity to try-out our software-router solution.
