Introduction to Precision Time Protocol (PTP) on IBM Z

Tags: Proceedings , SHARE Virtual Experience 2021

Precision Time Protocol, aka PTP, is a newer time synchronization protocol standard that was introduced on IBM z15. PTP as the external time reference for a Server Time Protocol (STP) Coordinated Timing Network allows for customers to achieve more accurate and precise time synchronization, which is a business critical issue for many IBM Z customers, particularly in the finance, banking and payment industries. PTP allows these customers to more easily comply with the ever increasingly stringent government regulations for time synchronization. Going forward PTP will play an increasingly important role for IBM Z and our customers. This session will introduce PTP to IBM Z customers, looking at the regulations, the technology of PTP, and how IBM is implementing PTP on z15. The session will also include insight into the future of PTP and latest developments in the standards. The speaker is IBM Z's time synchronization architect and team leader. He also represents IBM in the time synchronization standards bodies, and has helped write the latest standards.
