ABSTRACT:
A method for calibrating a propagation delay in a network trunk includes the step of calculating a time period Ti in a first network switch between sending a marker and receiving a trunk package acknowledgement marker from the second network switch, and a time period Tt in the second switch between receiving the trunk package and the marker and transmitting an acknowledgement marker containing the trunk package back to the first switch, the second switch appending the time period Tt to the acknowledgement marker before sending it back to the first switch. The time gap is read and a time delay caused by sending the trunk package on each channel is calculated. The second switch decodes the received trunk package and calibrates the propagation delay based on the time delay to determine a time gap between the packages in the same channel.
