Abstract

The Data Movement Manager (DMM) is a prototype interface that connects CERN's data management software, Rucio, with the Sofware-Defined Networking (SDN) service SENSE by ESNet. It enables SDN-enabled high-energy physics data flows using the existing worldwide LHC computing grid infrastructure. A key feature of DMM is transfer priority-based bandwidth allocation, optimizing network usage. Additionally, it provides fine-grained monitoring of underperforming flows by leveraging end-to-end data flow monitoring. This is achieved through access to host-level (network interface) throughput metrics and transfer-tool (FTS) data transfer job-level metrics. This paper details the design and implementation of DMM.
