      Packet marking
      - Firefly (R&E) dashboard was moved to ESnet and is now at:
        - https://public.stardust.es.net/d/b8dddac0-5b24-4739-9c8d-e88a05c1344f/scientific-network-tags3a-rande-dashboard?orgId=1
         - Waiting for feedback on this
         - This is ready to be deployed/tested on other collectors (Jisc ?)
         - Potential improvements to consider:
              - Translate exp/act IDs to strings so they can be shown in the graphs 
              - Calculate flow durations (from start and end times)
              - Calculate transfer rates (from start/end times and bytes sent/recv) - will be approx.
         - Validation - we have benefit of having just one site, so we could compare UNL internal stats, ESnet UNL and fireflies to see what is our coverage 

      Developments:
      - XRootd support for scitag HTTP headers  has been released (in 5.6.3)
         - https://github.com/xrootd/xrootd/blob/v5.6.3/docs/ReleaseNotes.txt
      - Testing will start on CERN EOS pre-production (fireflies will be sent to ESnet)
      - Waiting on deployment of Scitags support in Rucio, FTS production by ATLAS
       

      Packet pacing
      - Regular meetings moved to this meeting
      - Testbed Google sheet ready - please request access and add nodes that will participate (missing ESnet, Jisc nodes)
        - https://docs.google.com/spreadsheets/d/1U0VXIfWHfpK7bX7k2ucFep4Xo_4KQ5x-7rKD7e4az7Y/edit?usp=sharing
      - Testbed commisioning
        - Actions/changes needed and guides will be sent shortly (BBRv3 support, sysctl settings, etc. ) - mailling list will be created from contacts in the Google sheet
        - Implementation of the changes will be tracked in the Google sheet
      - Tests coordination - looking for test coordinators for each (or multiple) week(s) - first come first served ! - Carmen volunteered and already started some inital testing
