We demonstrate first results from our Lambda Station Project, part of the developments towards effective wide-area systems for LHC computing. We are using the DOE UltraScience Net as a resource for this R&D. This work shows managed switching of network flows to meet demand and response over wide area networks for the purposes of data streaming between LHC sites.

The capability we seek to develop can be summarized as being able to do in a dynamic, wide area grid environment for LHC experiments what we have done between workgroups at Fermilab for the Run II experiments. For the LHC systems, host issues, transfer protocols and the model of network provisioning are differs both from on-campus applications, and use of conventional wide area networks. For example, the ingest of data from CERN into production systems at Fermilab for Service Challenge 2, which was sustained at many gigabits per second for several weeks, used a network which is more like a "lightpath" than a conventional packet switched wide area network.
