Considerations for Deploying IEEE 1588 V2 in Network-Centric Data Acquisition and Telemetry Systems

Abstract

Network-centric architectures continue to gain acceptance in data acquisition and telemetry systems. Though networks by nature impose non-deterministic transit time of data through a given link, the IEEE 1588 standard provides a means to remove this jitter by distributing time messages to the data acquisition units themselves. But like all standards, they evolve over time. The same is true with IEEE 1588, which is releasing its second version later this year. This paper discusses the challenges of the first version of the IEEE 1588 standard that Version 2 set out to address, potential challenges with Version 2, and interoperability issues that may arise when incorporating a mixture of Version 1 and Version 2 devices.
