Precise time synchronization is becoming increasingly important in modern distributed systems. This talk will explore the key challenges of time synchronization in large-scale deployments. The first topic will introduce challenges of multi-NIC setups, where some of the PHCs will be synchronized, and how one can agree on the valid time across them. The second part introduces the Client Server Precision Time Protocol (CSPTP). Current 1588 profiles pose challenges for large-scale deployments and the new approach allows the servers to operate without keeping clients’ state information. We will then explore the “window of uncertainty” concept and its implications for accuracy and reliability. Additionally, we will discuss methods for achieving fast access to PHC (PTP Hardware Clock) time, enabling low-latency synchronization for time-sensitive applications.
