System Basics Introduction

PTP Clock Synchronization

The IEEE 1588v2 standard synchronizes the frequency and time from a master clock to one or
more slave clocks over a packet stream. This packet-based synchronization can be over UDP/IP or
Ethernet and can be multicast or unicast. Only IPv4 unicast mode with unicast negotiation is
supported.
As part of the basic synchronization timing computation, a number of event messages are defined
for synchronization messaging between the PTP slave clock and PTP master clock. A one-step or
