Session Abstract

[Kian-Tat Lim, SLAC via VIDEO]
The Large Synoptic Survey Telescope will take 6 GB of uncompressed image data every 18 seconds on a mountaintop in Chile, transferring it within 5 seconds to the main processing compute cluster at NCSA in Illinois. But this is just one of several large flows required to extract science from the LSST data. Besides describing these "feeds and speeds", this talk will also discuss flow characteristics that are somewhat unusual for science: guaranteed-bandwidth virtual circuits that can employ a modified TCP congestion control algorithm, time-domain multiplexing of flows over networks rather than pure packet multiplexing, and "bring your own bandwidth" connections for large data customers.
