• Steve Guendert Ph.D. - IBM Z Timing Hardware Systems Architect, IBM

The latest generation of IBM Z Systems family of mainframes is used by over 90% of the worlds 100 largest global banks as the computing platform they run their businesses on. The IBM Z also is heavily used by governments, and in other financial, insurance, and retail companies worldwide to the point where it is often said that the world's economy runs on IBM mainframes. This session will discuss the time synchronization regulatory changes that led to IBM studying the IEEE 1588 Precision Time Protocol (PTP), and what IBM is doing with PTP on the mainframe. It also will discuss ideas IBM has on highly resilient time synchronization networks to improve availability and security of this mission critical cyber infrastructure.
