Abstract：QoS supports of multiclass data service in IP network includes generally packet delay, throughput and loss rate, while the majority last research focus on either minimizing packet delay and loss or maximizing user throughput. In this paper, an algorithm DPAA (Dynamic Proportional Adaptive Algorithm) for assuring the difference service under traffic vary-time condition in Proportional Differentiated Services(PDS) model is proposed. The scheme takes into account the throughput, delay and loss rate of packets between classes simultaneously. Simulation indicates that the DPAA has a good performance compared to the previous works.
