 note = {We investigated how the arrangement of two packet scheduling algorithms (WFQ and FIFO) affects the application—level QoS of an audio—video streaming service over IP networks (typified by IPTV). We ran two computer simulations: (i) only the packet scheduling algorithms were applied, and (ii) both the packet scheduling algorithms and a media synchronization control were applied. Results showed that in case (i), a high application—level QoS with a relatively low delay was achieved when the WFQ was applied to congested nodes and to the node next to the media senders. In case (ii), a high QoS was achieved independently of the arrangement of WFQ nodes only if the bandwidth requirement was satisfied at the congested nodes., application/pdf},
