Abstract
A method can include obtaining, at a physical communication layer integrated with a communication interface, a data packet, detecting, by a detection circuit integrated with the physical communication layer, a portion of data in the data packet corresponding to a marker identifying the data packet, linking, by the physical communication layer based on the marker, a timestamp with the data packet, and transmitting, by the physical communication layer, the data packet linked with the timestamp.
