Interactive multimedia applications over multihop cell or packet-switched networks have strict bounds on delay, loss, and jitter. Much research has focused on how to best handle the networking issues related to supporting the Quality of Service (QoS) contracts without compromising network efficiency, i.e. improving network utilisation, and reducing connection packet loss and late delivery. This paper describes our novel technique, Network Constrained Smoothing, for smoothing video traffic into a server-side transmission schedule.Our approach combines QoS metrics about video connections together with network loading information in an algorithm that divides the schedule into equalsized intervals of constant bit-rate. We evaluate performance by simulation and compare with an existing smoothing technique, optimal smoothing. We show the benefits of using Network Constrained Smoothing to synchronise independent multimedia streams. The results show reductions in network loading at peak times and provide manageable information for routers about currentlysupported multimedia traffic.
