Abstract: As the core of VOD system, video servers need a largestorage capacity. Therefore, a hierachical storage structure is inevitable. Asa result, it's an urgent problem to find a suitable access control algorithm forVOD system based on hierachical storage structure. In this thesis, an unfair access control algorithm based cost factor is discussed. The computer simulation of the performance of this algorithm is shown, and satisfied results are achieved.
