IEEE 1588TMStandard for 

A Precision Clock Synchronization Protocol for 

Networked Measurement and Control Systems

Sponsored by the Technical Committee on Sensor Technology TC-9

IEEE Instrumentation and Measurement Society


This standard defines a protocol and time-sensitive components enabling precise synchronization of clocks in distributed systems. The protocol is applicable to systems communicating by local area networks including, but not limited to, Ethernet. The protocol enables heterogeneous systems that include clocks of various inherent precision, resolution, and stability to synchronize to a grandmaster clock. The protocol supports system-wide synchronization accuracy in the sub-microsecond range with minimal network and local clock computing resources. The standard specifies how to customize the protocol for specific application domains using a 1588 profile. The technology defined by IEEE 1588 is currently being used in the following industries: telecommunications, power generation and distribution, industrial automation, robotics, data acquisition, test and measurement.

A study group has been authorized to develop a Project Authorization Request (PAR) for the revision of the IEEE 1588-2008 Standard.
