8th White Rabbit Workshop We have learned a lot about..... Customs Plug Fest Our WR gear was stuck in customs - If you bring it yourself → 24h later you get it. - If you send it → You don't get it Cesar Prados, GSI 8th White Rabbit Workshop

8th White Rabbit Workshop White Rabbit in the Plug Fest and Goals Plug Fest OK Correctness of Pdelay sync mechanism in PPSI OK WR P2P Transparent Clock with minor issues OK Performance of new non-WR PPSI servo OK IPv4 with minor issues OK PTP Domains ? WRPTP over SyncE switch Cesar Prados, GSI 8th White Rabbit Workshop

8th White Rabbit Workshop Best Paper Award: Conference “Using a multi-source NTP watchdog to increase the robustness of PTPv2 in Financial Industry networks” Interesting Papers: “Precise Clock Parameter Estimation and Ground Truth Capture for Clock Error Measurements using FPGAs” “Experimental verification of the egress and ingress latency correction in PTP clocks” “PPSi – A Free Software PTP Implementation” Cesar Prados, GSI 8th White Rabbit Workshop

8th White Rabbit Workshop Notes Best Paper Award: Al single point of failure in the PTP protocol that affects its robustness, and ongoing regulatory requirements In finance markets using a multi-source NTP watchdog Conference Interesting Papers: 1)propose a mechanism to estimate clock parameters between two clocks using TDC. Simultaneously, we have proposed a ground truth capture methodology for clock error measurements. 2) present a measurement setup that enables the direct measurement of both the ingress and egress latencies of a PTP clock.
