Abstract
According to example embodiments of the present invention, predetermined patterns are inserted into data streams and exchanged between a master node and a slave node. By recognizing the patterns near the underlying interface of the physical layer, the master node and slave node can generate timestamps that exactly identify when the respective messages leaves and/or arrives at the physical layer. The slave clock can be synchronized to the master clock based on such timestamps.
