-= About PTP and clock synchronization error events
+= Monitoring PTP clock synchronization with fast event notifications
 
+[role="_abstract"]
 Cloud native applications such as virtual RAN (vRAN) require access to notifications about hardware timing events that are critical to the functioning of the overall network.
 PTP clock synchronization errors can negatively affect the performance and reliability of your low-latency application, for example, a vRAN application running in a distributed unit (DU).

 {product-title} uses the PTP Operator with `linuxptp` and `gpsd` packages for high precision network synchronization.
 The `linuxptp` package provides tools and daemons for PTP timing in networks.
 Cluster hosts with Global Navigation Satellite System (GNSS) capable NICs use `gpsd` to interface with GNSS clock sources.
