[Linuxptp-users] Question about delay estimation and offset

2023-05-12 Thread Víctor Vázquez Rodríguez
Hi all, We are doing some research based on ptp4l and I noticed that it doesn’t perform delay estimation and offset estimation on the same cycle. That is, the client updates only the estimated delay when it receives a DELAY_RESP and then updates the offset estimation (and corrects the clock) wh
