Abstract
A network component comprising a processor configured to implement a method comprising promoting transmission of a first frame comprising a first timestamp associated with a transmission time of the first frame, recognizing a reception of a second frame having a reception time, wherein the second frame comprises a second timestamp comprising a downstream node delay associated with a downstream node, measuring a total delay between the transmission time of the first frame and the reception time of the second frame, and calculating a transport delay using the total delay and the downstream node delay. Also disclosed is a clock synchronization method comprising receiving a first frame comprising a first timestamp associated with an upstream clock at a reception time, sending a second frame at a transmission time, and measuring a downstream node delay between the reception time and the transmission time, wherein the second frame comprises the downstream node delay.
