Abstract
A device, system, and method determines a forwarding delay through a networking device. The method is performed at the networking device including a transceiver and an always running timer (ART). The method includes generating a first timestamp using a first clock of the transceiver when a packet to be forwarded has been received. The method includes capturing a first ART time corresponding to the first timestamp. The method includes generating a second timestamp using a second clock of the transceiver when the packet to be forwarded has been transmitted. The method includes capturing a second ART time corresponding to the second timestamp. The method includes determining a forwarding delay based on the first and second timestamps and the first and second ART times.
