PTP
Precision Time Protocol (PTP) is a network protocol that synchronizes the clocks of devices to a highly accurate time reference, enabling precise coordination across distributed systems.
PTP delivers sub-microsecond time synchronization between networked devices, making it essential for environments requiring high-precision timing, such as industrial automation, telecommunications, financial trading, and broadcasting.
PTP operates using a master-slave architecture, with a Grandmaster clock providing the reference time and slave devices adjusting their clocks accordingly. Two-way communication and specialized clock types (Boundary, Transparent) compensate for network delays and optimize accuracy.
PTP can be implemented in hardware or software, with various profiles tailored to application needs (e.g., IEEE 1588-2008, Power, Telecom). Best practices include careful network configuration, use of dedicated timing hardware, and regular monitoring for drift and accuracy.
