      Joe remonds there is the call for demos with deadline the May 17th
      Edoardo says that CERN will nor repeat the NOTED demo of the last two years. But if there are new ideas, CERN will contribute.
      Harvey states the need for Gen5 DTN servers at CERN to demonstrate the capability  to fill the transatlantic 400G links. 
      Edoardo says that CERN is ready to host them, but there is no much budget to buy. 
      Marian and Edoardo will talk to the CERM storage team to understand if there id any server that could be used.
      Tom says FAB has mulltiple servers at CERN, but none with 400G interfaces. Tom will check if it is possible to increase the connection between FAB and the ESnet router at CERN. 
      Joe will ask Frederic Luoi if they have a DTN at CERN.

      For a SciTags demo, Tristan proposes to compare scitags with hop-by-hop headers to the flowlabel version. 
      Jim Chen: Starlight is also interested in participating in this demo.
      Marian can support the demo.
