WebApr 7, 2024 · gPTP ingress timestamping in C. I have been trying to implement ingress timestamping of gPTP event messages (SYNC and/or FOLLOW_UP) messages. Basically, there are two Time Sensitive Network (TSN) .ie. device-side and network-side, which are implemented in a 5GS. So gPTP packets flows from the NWTT-->DSTT. WebThe file gPTP.cfg (available in configs folder of Linux PTP source) specified by the -f option contains the configuration options to required to run ptp4l in gPTP mode while the -i option specifies the network interface this instance of ptp4l is controlling. The --step_threshold is set so ptp4l converges faster when “time jumps” occur (more on this later).

WebThe Precision Time Protocol ( PTP) is a protocol used to synchronize clocks in a network. When used in conjunction with hardware support, PTP is capable of sub-microsecond accuracy, which is far better than is normally obtainable with NTP. PTP support is divided between the kernel and user space.
