Abstract
Methods and apparatus for synchronizing a first clock of a transmit node and a second clock of receive node in a packet network are provided. Consecutive intervals of time-stamped packets transferred from the transmit node to the receive node are selected. The consecutive intervals have a difference in delay noise within a defined acceptance window. A correction factor is determined for the second clock in accordance with transmit and receive time stamps of transferred time-stamped packets bounding the consecutive intervals. The correction factor is applied to the second clock to synchronize the second clock of the receive node with the first clock of the transmit node.
