In this paper, we propose a novel VOD server architecture and a dynamic prefetch buffer allocation algorithm based on popularity. This can drastically improve the maximum number of streams a drive can support, with a small startup latencies. The primary design goal is to guarantee glitch free operation for maximum number of users. Detailed simulation is carried out and compared with the performance parameters of the static allocation algorithm.
