Abstract

A method is disclosed for recovering timing information between master and slave nodes interconnected over a packet network having an underlying time grid with a distinct granularity. A series timing packets are exchanged between said master and slave nodes to measure the time offset of the time grid relative to clocks at the master and slave clocks. This offset is then used to either adjust the local clock at the slave node, or generate the clock using a digital controlled oscillator.
