In this research, two pro-active dynamic quality of service (QoS) control schemes are designed, the dynamic QoS control scheme with delay estimation, and the hybrid dynamic QoS control scheme. The two schemes aim at fulfilling the requested level of QoS while simultaneously achieving high resource utilization. Emphasis is placed upon buffer management via administration schemes of packet loss and packet delay. The results obtained through the simulation models have shown that the two schemes have significantly improved the average delay for different traffic patterns. The proposed scheme can be adopted for multimedia applications to enhance the QoS in terns of better delay and improved resource utilization.
