Abstract:
1. A method, comprising: receiving in a network element a packet, which comprises a delay field that indicates an overall time delay accumulated by the packet until arriving at the network element; upon receiving the packet, substituting in the delay field an interim value, which is indicative of a difference between the overall time delay and an arrival time of the packet at the network element; before sending the packet from the network element, updating the overall time delay in the delay field based on the interim value and on a departure time at which the packet is to exit the network element; and transmitting the packet, comprising the updated overall time delay, from the network element; wherein substitution of the interim value is performed at an ingress port at which the packet enters the network element, and wherein updating of the overall time delay is performed at an egress port at which the packet exits the network element.
