An Active Queue Management Algorithm Based on DiffServ Model

Abstract

DiffServ model is a main model that guarantees QoS in modern-Large-scale network., On the basis of RIO-C, the paper introduces an Active Queue Management algorithm -- PFRIO that is suitable for DiffServ model. The algorithm increases the fair for bandwidth allocation and the network’s capacity to hand of sudden data flow, and improves the overall performance of DiffServ model effectively.
