The general multi-tiered admission control strategies restrict the system throughput for two reasons.Firstly there is no consideration on the dependency between every tier, and secondly the strategies have the delay characteristic.In this paper, a 2-level fuzzy admission control algorithm is proposed to solve this problem.The first level named load controller judges the load situation of each tier by the resource consumption and requests delay.The second level named admission controller decides the admission rate of the current session by probability statistics.The experiments show that the algorithm can overcome the limitation of general admission control strategies and improve the system throughput.
