Traffic load in the aggregate class of DiffServ network varies dynamically. However, when the traffic load proportion of different aggregate classes is not equal to the assigned weight proportion in the scheduling algorithm, such as the WFQ algorithm, the packets in different aggregate classes will receive unfair treatment, even though these classes have the same priority. Hence, research on fairness-oriented dynamic bandwidth allocation in DiffServ becomes very important. In this paper, in order to balance the packet loss for fair bandwidth allocation, we propose a traffic load-based dynamic bandwidth allocation approach, which especially considers both the current weight proportion and queue increment proportion for calculating the new weight proportion. Experiment shows the valid of our approach.
