Verification of Network Time Synchronization Using PTP - Real-World Challenges and Solutions

Explore the intricacies of network time synchronization in this 43-minute conference talk by Johannes Zink from Pengutronix e.K. Dive into the world of Precision Time Protocol (PTP) and its ability to provide clock synchronization down to the nanosecond range. Learn about hardware timestamping of PTP packets and the Linux kernel's PTP hardwareclock infrastructure. Discover the challenges in configuring components and setting up PTP daemons and hardware. After a brief introduction to PTP and synchronization of PTP hardware clocks, examine various methods for measuring clock synchronization, comparing their pros and cons. Through real-world project examples, identify common pitfalls when initiating new PTP projects and learn how to avoid them. Gain insights into debugging issues such as misleading software debug outputs and time jumping back and forth. Perfect for those working with realtime network applications requiring tight time synchronization between network nodes.
