Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
P1588a
Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems Amendment: Enhancements for Best Master Clock Algorithm (BMCA) Mechanisms
This amendment: a)tEnhances existing mechanisms and creates new ones that contain information about the time accuracy to support execution of BMCAs, while maintaining backward compatibility, or assist in the development of alternate BMCAs; b)tProvides informative text to explain the execution of the BMCA; c)tProvides informative text to guide the creation of alternate BMCAs; d)tProvides an optional mechanism for managing Announce timeout; and e)tCorrects errors in the text and clarifies passages that are unclear.
P1588b
IEEE Draft Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems - Amendment: Addition of Precision Time Protocol (PTP) mapping for transport over Optical Transport Network (OTN)
This draft standard is an amendment of IEEE Std 1588™-2019. This amendment: a) Adds a normative annex that specifies the mapping of PTP to OTN; b) Adds an enumeration value to the network Protocol table (Table 3, in 7.4.1); c) Corrects errors in the text and clarifies unclear passages.
P1588c
Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems Amendment: Clarification of Terminology
This amendment will improve the terminology in the standard, and more completely specify the behavior of the protocol, in the following ways: u2022tClarification of the term u201cretransmitu201d u2022tElaboration of how type-length-value (TLV) message extensions are handled by Boundary Clocks and Transparent Clocks u2022tFix editorial errors and clarify unclear statements.
P1588d
Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems Amendment: Guidelines for selecting and operating a Key Management System
This amendment enhances the security option of the IEEE 1588-2019 in the following ways: u2022 Add guidelines on the selection and operation of specific key management technologies to Annex P. This involves the currently considered key management options and may also leverage additional key management approaches like Network Time Security (NTS). u2022 Make changes to the standard necessary to support automated key management mechanisms u2022 Fix errors and clarify unclear statements .
P1588e
Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems Amendment: MIB and YANG Data Models
This amendment specifies MIB data models and YANG data models for all data sets of IEEE Std 1588-2019, and other possible amendments to IEEE Std 1588-2019. The amendment uses the MIB and YANG standards as specified by the Internet Engineering Task Force (IETF). The amendment does not specify notifications, only configuration and state for data sets. In addition to introductory text and other normative text, the amendment produces module files that specify the MIB and YANG data models. The module files produced by the amendment are located on a public repository, and the content of each module file is not listed in the IEEE Std 1588 amendment document. The amendment will include the references to each module file. This amendment corrects errors in the text and clarifies unclear passages.
P1588g
Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems Amendment: Master-slave optional alternative terminology
This amendment adds an optional alternative suitable and inclusive terminology to the terms u201cmasteru201d and u201cslaveu201d but it does not replace the terms u201cmasteru201d and u201cslaveu201d In addition, the amendment fixes errors in the standard and clarifies unclear passages.
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
1588-2019
IEEE Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems
In this standard, a protocol is defined 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-nanosecond time transfer accuracy can be achieved in a properly designed network.
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
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.
1588-2008
IEEE Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems
This standard defines a protocol enabling precise synchronization of clocks in measurement and control systems implemented with technologies such as network communication, local computing and distributed objects. The protocol is applicable to systems communicating by local area networks supporting multicast messaging 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 default behavior of the protocol allows simple systems to be installed and operated without requiring the administrative attention of users. The standard includes mappings to UDP/IP, DeviceNet and a layer-2 Ethernet implementation. An Interpretation is available at http://standards.ieee.org/reading/ieee/interp/1588-2008.html
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
