Many network applications like motion control or precise monitoring of machines need precise knowledge about the time synchronization accuracy. But time synchronization accuracy depends on the performance of PTP nodes, network topology, environmental conditions and various other factors. This makes the determination of synchronization accuracy a complex task. A mechanism for determining the worst...
Various applications require or can benefit from high accuracy of synchronization between networked elements. The White Rabbit (WR) project includes enhancements to the now widespread IEEE1588 Precision Time Protocol (PTP) to support supplying synchronization in the sub-nanosecond level.
The IEEE1588-2008 (precision time protocol, PTP) is being deployed in various application domains including domains requiring specified synchronization performance. Deploying appropriately defined monitoring functions will support the continuous operation of synchronization networks at the required synchronization quality. The paper addresses the field of synchronization monitoring, first introducing...
