I have a setup with 3 PC’s where PC 1 sends data to PC 3 trough PC 2 (all connected trough switch). Im measuring latency for some data packets using Wireshark and to keep all pcs system time in sync Im using PTP (PTPD where PC 2 is master). On PC1 I’m getting outputs similar to this this:
2022-05-26 20:02:03.136338, slv, 901b0efffef3035e(unknown)/1,
0.000112484, -0.000039671, 0.000103942, 0.000065891, 15172.497079102, S, 0.000112582, 1680, 0.000003502, 65813, 15152, 184, 0.000065891, 0.000103942
On PC3:
2022-05-26 20:02:32.131987, slv, 901b0efffef3035e(unknown)/1,
0.000046498, -0.000002006, 0.000046235, 0.000044993, -1369.228802734, D, 0.000046042, 126, 0.000001405, 2067, -1341, 13, 0.000044993, 0.000046235
How can I estimate my latency error? Is it correct just to average Offset From Master output values?
