Latenzbudget (EN)

Definition

The latency budget refers to the maximum allowable delay in a system or network that does not impair the function of time-critical applications. In time synchronization, the latency budget includes the sum of all delays from the time source to the target device. Conscious management of the latency budget is crucial for the reliability of real-time systems. By minimizing the latency budget, you can significantly improve the accuracy of time synchronization.
