IEEE 1588-2008, also known as PTP Version 2, is not backward compatible with the 2002 version. IEEE 1588-2019 was published in November 2019 and includes backward-compatible improvements to the 2008 publication. IEEE 1588-2008 includes a profile concept defining PTP operating parameters and options.

IEEE 1588 is a protocol designed to synchronize real-time clocks in the nodes of a distributed system that communicate using a network. Hardware? IEEE 1588: Target is groups of relatively stable components, locally networked (a few subnets), cooperating on a set of well defined tasks. NTP: (Network Time Protocol, RFC 1305).

Jun 16, 2020 · Sub-nanosecond time transfer accuracy can be achieved in a properly designed network. Scope: This standard defines a network protocol, the Precision Time Protocol (PTP), enabling accurate and precise synchronization of the real-time clocks of devices in networked distributed systems.

Nov 16, 2024 · 1588v2是网络测量和控制系统的精密时间同步协议标准，也可称为PTPv2（Precision Time Protocol Version 2，精密时间协议V2版本）。 1588v2是由IEEE标准组织发布的业界标准，用于实现设备之间的高精度时间同步，也可以用来进行设备之间的频率同步。 借助于硬件记录时戳的优势，1588v2相对于 NTP （Network Time Protocol，网络时间协议），可以达到亚微秒级的时间同步精度，能够满足无线基站的时间同步需求。 相比于传统GPS高精度 …

Synchronous Ethernet (SyncE—ITU-T Rec. G.8261) and 1588 (IEEE 1588-2008 or version 2) are technologies used for distribution of frequency and time of day (ToD). The architecture and features of SyncE are very similar to those found in SDH/SONET networks.

Apr 11, 2024 · IEEE 1588v2, also known as Precision Time Protocol Version 2 (PTPv2), is a precision clock synchronization protocol designed for networked measurement and control systems. It is an industry standard released by IEEE to achieve high-precision time and frequency synchronization between devices.

Nov 25, 2024 · 1588v2, also called Precision Time Protocol Version 2 (PTPv2), is a precision clock synchronization protocol for networked measurement and control systems. 1588v2 is an industry standard released by IEEE for high-precision time synchronization and frequency synchronization between devices.

“The purpose of a PTP profile is to allow organizations to specify specific selections of attribute values and optional features of PTP that, when using the same transport protocol, inter-work and achieve a performance that meets the requirements of a particular application.”

It enables standard Ethernet terminal devices to synchronize time and frequency from a clock source. 1588 includes 1588v1 and 1588v2. 1588v1 provides sub-millisecond precision time synchronization, and 1588v2 provides sub-microsecond precision time synchronization. 1588v2 is a time synchronization protocol.

Abstract: IEEE 1588 is a standard for a precision clock synchronization protocol for networked measurement and control systems. IEEE 1588 protocol can provide sub-microsecond accuracy. However, most synchronous systems generate timestamps using software-generated methods or proprietary chips.
