Fuzzy Logic Based Admission Control on Video Servers

A novel fuzzy logic based admission control algorithm on VBR videos is proposed. By the on-line adjust- ment of scheduling period, residual system resources such as disk I/O bandwidth and buffer space are in a dynamic balance state, which enhances greatly the integrated utilization of system resources. The result of simulation shows the algorithm can increase admission rate by about 30% than that of optimal fixed period algorithm. The algorithm al- so can increase admission rate by 8% than that of former algorithm with dynamic scheduling period, and its availabili- ty is strengthened obviously.
