The Precision Time Protocol (PTP) is a protocol for clock synchronization throughout a computer network with relatively high precision and therefore potentially high accuracy. In a local area network (LAN), accuracy can be sub-microsecond – making it suitable for measurement and control systems. [1] .

Precision Time Protocol (PTP) is a protocol to synchronize clocks in a computer network, similar to Network Time Protocol (NTP). NTP is accurate, under ten milliseconds. PTP, however, is …

Jun 20, 2022 · Precision Time Protocol (PTP) is a protocol that promotes the synchronization of clocks throughout a computer network. This protocol is used to synchronize clocks of different types of devices. PTP was led by John Edison in 1588 for the standardization and was published in the year 2002.

Apr 2, 2024 · Precision Time Protocol (PTP), defined in the IEEE 1588 standard, offers a solution for precisely synchronizing clocks throughout a computer network. Unlike NTP (Network Time Protocol), which aims for millisecond-level accuracy, PTP achieves synchronization to the sub-microsecond level.

PTP (Precision Time Protocol) is basically used for the clock synchronization throughout a computer network. PTP clock accuracy is in the sub-microsecond range.

PTP is used to synchronize the clock of a network client with a server (similar to NTP). However, PTP is mainly used in LANs, with much higher precision than NTP (usually 10's of microseconds to 10's of nanoseconds).

PTP comes in different flavors (Profiles), depending on the environment it shall be used in. Profiles define communication medium mappings (Ethernet, Profinet, etc.), message rates, the delay mechanisms, default values of datasets and sometimes much more:

Mar 18, 2025 · Precision Time Protocol (PTP) is a time synchronization protocol that synchronizes clocks throughout a computer network as defined in the IEEE 1588 standard, Precision Clock Synchronization Protocol for Networked Measurement and Control Systems. PTP clock synchronization in packet-based network infrastructure includes distributed internal device …

Precision Time Protocol (PTP) enables server time synchronization with sub-microsecond to nanosecond precision, surpassing the previous technology, Network Time Protocol (NTP), which only provides millisecond precision.

Jan 19, 2024 · PTP, or precision time protocol, is a powerful and flexible protocol that offers high-performance time synchronization for various applications that require precise and consistent timing across different devices and networks.
