IEEE 1588-2088 perspectives and opportunities

摘要

The revised precision time protocol presents opportunities and some real-life challenges. The PTP (Precision Time Protocol), which the IEEE defined under 1588-2008, represents a step change in the distribution of time and frequency across WANs (wide-area networks). The telecommunications industry is, in parallel, evolving to packet-transport systems, isolating services and systems from their clock sources. As a result, the mobile sector, in particular, represents the first large-scale opportunity for IEEE 1588.
