5. How do we continue?  PanDA-XRootD work continuing through US ATLAS funds  What about SDN?  No new external funding for this work  We should organize US ATLAS proposals  There are no fully working end-to-end distributed systems today  We expect systems to start showing up in 1-2 years  ATLAS can benefit from early adoption  US ATLAS planning needed  Realistically, this is a long term project June 29, 2015 Kaushik De 5
