But owing to the drawbacks of the original Internet best effort design, such network will often be in chaos if we do not employ any QoS mechanism. CAC (call admission control) is one of QoS mechanisms and it maintains performance by limiting system utilization. However, the most conventional CAC algorithms are utilizatoin-based and measurement-based CAC algorithm, both have become important research topics. Among the research work, most of them wants to increase system utilization but not to degrade the quality of service. In this thesis, we propose a call admission control algorithm, which handles longlive and short-live dlows differently. Under such mechanism, we show that not only one can guarantee the quality of each flow, but it is also possible to improve the system utilization. Finally, we employ simulation to valide the effectiveness of this CAC algorithm to support streaming media services. |
