FNAL input

• The satisfaction of the US HEP community is very
  important to Fermilab.
• The CMS T1 center at Fermilab is the only center
  in the hemisphere. There are many presentations
  were all T1's are of equal capacity. These sorts
  of presentations understates what is required
  in the US.
• US CMS view the weight of the FNAL at 2-3 times a
  nominal T1.
• Fermilab has the experience and potential to
  ingest and serve all the data if needed as a
  permanent or temporary contingency.
• Do not under-estimate the technical contingency
  well-provisioned networking will provide the LHC
  project during shake down.
• Inadequate Transatlantic network would have to be
  mitigated by more storage, acceptance of delays
  and more planning.

Discussion

• Mnay cricitized the TDR network requirements as
  characterizing part of the problem, leaving out
  other parts of the problem.
• Funding for Esnet plans is TDB.
• Abiliene futures were quite tentative.
