摘要： It is disclosed a method for updating a cumulative residence time of a synchronization packet received at a node of a packet-switched communication network. The cumulative residence time is equal to a cumulative sum of residence times of the packet at nodes interposed between a further node which has generated the packet and the node. The node comprises an ingress circuit and an egress circuit. The method comprises: receiving the packet at the egress circuit from the ingress circuit; at a timestamp generator of the egress circuit, generating a timestamp; at the egress circuit, calculating a virtual timestamp based on the timestamp and on an estimated variable delay that will be undergone by the packet due to buffering in a buffer located downstream the timestamp generator; and, at the egress circuit, using the virtual timestamp for updating the cumulative residence time, before transmitting the packet to a still further node.
