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
