Abstract

Timekeeping and highly accurate, precise time synchronization are key requirements for modern information technology systems. While true for several industries, this is especially true for industries involved in transaction processing such as the financial industry. As such, the IBM Z Sysplex needs highly accurate timing/timekeeping and synchronization technology to ensure data integrity, and to also provide the ability to reconstruct a database based upon logs. Recently enacted changes and new regulatory requirements, both in Europe and the United States, have brought increasing attention to time synchronization accuracy. These regulations spurred an interest, both from IBM Z and from our IBM Z clients, in the IEEE 1588 Precision Time Protocol (PTP) being implemented in IBM Z. This article explains the history of PTP, PTP technology, the regulations that led IBM to introduce PTP to IBM Z, PTP's implementation on IBM Z, and IBM's involvement and leadership in the development of the PTP technology and standards going forward.

基于IEEE 1588精确时间协议(PTP)的Sysplex时间同步

计时和高度准确、精确的时间同步是现代信息技术系统的关键要求。虽然一些行业是如此，但金融业等涉及交易处理的行业尤其如此。因此，IBM Z Sysplex需要高度准确的计时/计时和同步技术，以确保数据的完整性，并提供基于日志重建数据库的能力。欧洲和美国最近颁布的变化和新的监管要求越来越引起人们对时间同步准确性的关注。这些规定激发了IBM Z和我们的IBM Z客户对在IBM Z中实现的IEEE 1588精确时间协议（PTP）的兴趣。本文解释了PTP的历史，PTP技术，导致IBM将PTP引入IBM Z的规定，PTP在IBM Z上的实现，以及IBM在PTP技术和标准发展方面的参与和领导。
