BISv2 and SMPv2 Reliability Studies

Tuesday 16 Dec 2025, 15:30 → 17:00 Europe/Zurich

30/6-019 (CERN)

15:30 → 15:40 BISv2 deployment and testing for North Area, SPS ring & SPS to LHC extraction/injection

o Overview of installations
o Overview of testing strategy (how often BIS in test mode, how often user connections are checked,…)

Speaker: Ivan Romera Ramirez (CERN)

15:40 → 15:55 BISv2 Reliability studies for North Area, SPS ring & SPS to LHC extraction/injection

Overview of model and method
Results for the three installations
Discussion - BISv2 (users) testing strategies (should we do similar monitoring as we do for SPS injection BIS; can we leverage ACCTesting to test the whole chain including users)

Speaker: Lukas Felsberger (CERN)

16:00 → 16:15 SMPv2 data transmission via White Rabbit

Overview (what is done by SMP and what by WR, how and where does SMP inject data in WR network, comparison with GMT, testing done so far)

Speaker: Raffaello Secondo (CERN)

16:15 → 16:30 Reliability Analysis of SMPv2 data transmission via White Rabbit

o Methodology
o Explaining PROFIsafe – which we take as reference
o Results for SMP via WR analysis using eliminative argument (and PROFIsafe as reference)
o Discussion on – baseline of CRC, sequence check, timeout enough or do we need latency check; how can we test against failure cases covered by latency check vs. timeout

Speaker: Lukas Felsberger (CERN)

16:35 → 16:45 SMPv2 Hazard Chain update for North Area

Speaker: Lukas Felsberger (CERN)
