There is always a trade-off between system profits and the Quality of Service (QoS) in service-oriented systems. Especially in the case of grid-based large-scale multimedia services systems which serve more classes of requests with different significance, the larger number of the requests admitted doesn't necessarily lead to a higher profit rate. This paper presents a novel layered threshold-based admission control strategy for such system. This strategy provides more guarantees to higher-priority requests by assigning them more resources reservation. Meanwhile, by the layered setting of the resources, the service system can also keep the agility of the admission control procedure and achieve higher profits. Theoretical evaluation and simulations are carried out to demonstrate the effectiveness and flexibility of the proposed strategy.
