Abstract:
In a method of recovering timing information over packet networks, raw network delays are measured using timing packets sent between a transmitter and receiver. The expected delay is predicted using a minimum statistics adaptive filter to track local minima of measured time delays over a smoothing window. Only those incoming timing packets which meet a particular criterion relative to the expected delay within a smoothing window are selected, and a local clock is adjusted based on the measured timing delays from the selected timing packets.
