Abstract
A method of recovering timing information in a packet network, involves detecting quiet periods in the packet network when network packet delay variation (PDV) is low. A frequency prediction unit is trained during the quiet periods to learn output clock variations of a timing recovery unit to permit the frequency prediction unit to predict frequency update values for a local oscillator during non quiet periods taking into account the historical output clock variations during quiet periods. The output of the frequency prediction unit is used as the active frequency update values during non quiet periods.
