Abstract
In this paper, a stream service strategy based on the adaptive buffer sharing and prefetching policy for the continuous media stream service is proposed. In the proposed caching policy, a stream is given one of the three service modes- direct, shared or object- with its requested object’s access patterns and frequency. With direct mode, a stream is serviced directly from disk using its own read-ahead buffer, which is necessary to buffer the speed discrepancy between disk’s transfer rate and user’s playback rate for the requested stream. In shared mode, the interval between two consecutive streams accessing the same object is cached whereas in object mode, which could be set when the access frequency of the requested object exceeds a given threshold; an object is cached in its entirety. The service mode of each object could be changed dynamically with its access frequency.
