(EN)Data streams are transmitted from a node (BS) towards a receiver in a communication network in the form of data packets for play out via a reproduction buffer at the receiver. The data packets are arranged in a scheduling queue (SQ) and dropped from the scheduling queue (SQ) if their sojourn time (t) in the queue (SQ) exceeds a given drop deadline (d). The reproduction buffer (B) is emulated at the node (BS) in order to determine respective playout values (po) for the data packets which are indicative of expected playout instants (p) for the data packets by the reproduction buffer at the receiver. The drop deadlines (d) are assigned to the data packets as a function of the respective play out values (po) determined via the reproduction buffer as emulated at the node (BS).
