Abstract: New international academic collaborations are generating daily data sets in the order of terabytes in size. Often these data sets need to be moved in real-time to a central location to be processed, archived and then shared. In the field of astronomy, data sets are usually created in remote locations, often away from the processing facilities. To send data sets to processing facilities, high bandwidth network infrastructures need to be provided to transport these data sets across very long distances, relying on multiple network operators. Creating an end-to-end path involving multiple network operators, technologies and interconnections often adds conditions that make the real-time movement of big data sets challenging. The Large Synoptic Survey Telescope (LSST) is an example of an astronomical application imposing new challenges on multi-domain network provisioning activities. This paper introduces an ongoing effort to guarantee an efficient network configuration capable of handling LSST data transfers across multiple network operators from South America to North America.
