摘要 A great number of video clips can be stored in the optical jukebox in VoDSystems. In this paper a scheduling scheme, called Combined MQL/FCFS (CMF), of short video clips inthe jukebox is proposed. Simulation shows that the proposed scheme balances the efficiency andfairness, and reduces the defection probability and increases the throughput significantly comparedwith MQL and FCFS schemes.
