1588-2002 - IEEE Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems
Replaced by IEC 61588-2004 (SH95292 or SS95292) Dual-logo document Abstract: A protocol to synchronize independent clocks running on separate nodes of a distributed measurement and control system to a high degree of accuracy and precision is specified. The protocol is independent of the networking technology, and the system topology is self-configuring.
1588-2019 - IEEE Approved Draft Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems
This standard defines a protocol that provides precise synchronization of clocks in packet-based networked systems. Synchronization of clocks can be achieved in heterogeneous systems that include clocks of different inherent precision, resolution, and stability. The protocol supports synchronization accuracy and precision in the sub-microsecond range with minimal network and local computing resources. Customization is supported by means of profiles. The protocol includes default profiles that permit simple systems to be installed and operated without the need for user management. Sub-ns time transfer accuracy can be achieved in a properly designed network.
