Introduction

The DOCA Firefly service enables time syncing services based on PTP4L. It can also enable PPS if the used DPU supports this capability.

PTP

The 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 (Network Time Protocol). PTP support is divided between the kernel and user space. The ptp4l program implements the PTP boundary clock and ordinary clock. With hardware time stamping, it is used to synchronize the PTP hardware clock to the master clock.
