A Dynamic Bandwidth Allocation and Call Admission Control Method for Quality of Service Control of VBR Video Traffic

초록

In this paper, we have proposed a dynamic bandwidth allocation and call admission control method, which can support users QoS requirements in terms of loss ratio and average delay very well and at the same time can achieve high utilization. The proposed mechanism dynamically adjusts the necessary bandwidth by the networks based on the provided quality of service satisfaction degree of each connection in respect to the users requirements. Some simulation results show that our proposed dynamic approach can provide efficient resource management and desired level of quality of service. Our future research in this area may involve more robust call admission scheme and the QoS control for maximum transfer delay, which is considered very important QoS parameter for real time videos.
