Claim 0:
1. A method for synchronizing a computing device to a master device comprising:
receiving a master timing reference from an intermediate device to the computing device over a dedicated data channel, wherein the master timing reference is generated by the master device; and
synchronizing a slave timing reference of the computing device to the master timing reference to a resolution within one tick of the master timing reference using a snapshot of the master timing reference transmitted over the dedicated data channel and a fixed known delay for a data packet containing the snapshot to be transmitted between the master device and the computing device via the intermediate device, the fixed known delay including an internal processing delay at the master device and transit time between the master device and the computing device, wherein the transmit time includes a constant retransmission processing delay for each hop between the master device and the computing device and a number of hops between the master device and the computing device.
