SC23 status:
- DTNs: Starlight (ready/have access), KIT (in prep), CERN (ready - connection TBD), UVic (in prep ?),
- Collectors: ESnet (ready) - will need access from CERN; need to check if firefly netlink data will work (Andy)
- Dashboards: CERN (in prep) - Grafana/Prometheus to be configured (Marian);
Got access to the InMon dashboard, can try to test it with linux agent (network sflow exports will need to be configured by SCinet)
- High-touch: visualisation (in prep) - python workbook to be shared (Yatish)
RNTWG packet marking - list of activities:
- Collectors developments (needed):
. - flowd extension to send netlink data (if only in state:"end" firefly then we also need to research ways to compress time series data)
- access to GEANT data source to check if we could show utilisation + fireflies side by side
- determine if we could plot data side by side with WLCG network monitoring
. - dashboard to show netlink data coming from flowd
- forwarding fireflies to another collector
- Storage and transfers developments
- dCache (needs testing)
- Rucio
- FTS/gfal2 (progressing)
- flowd in EPEL
- R&D
- Use HBH option (instead of flow label)
- Extension header reachability/drop rate study needed
- Find ways how to implement HBH in Linux and eBPF
- Others:
- CHEP2023 paper submitted (we should update scitags.org with publications)
RNTWG packet pacing - meeting next week (https://indico.cern.ch/event/1329666/) - BBRv3
