Abstract: A method, apparatus and computer program product receive, at a network node of a communication network, information about an accumulated packet delay in the communication network. The method, apparatus and computer program product estimate next hop transport delay and estimate or measure a processing delay of the network node. The method, apparatus and computer program product update the accumulated packet delay by adding the next hop transport delay and the processing delay to the accumulated packet delay. The method, apparatus and computer program product cause transmission of information about the accumulated packet delay in a header of a packet carrying user data or a control packet in the communication network to a next hop node of the communication network.
