Abstract
Buffer space and disk bandwidth resources in a continuous media server are continuously re-allocated in order to optimize the number of continuous media requests which may be concurrently serviced at guaranteed transfer rates using on demand paging. Disk scheduling is provided to ensure that whenever an admitted request references a page of data, the page is available in a buffer for transfer to a client. Data for continuous media data files are stored on disk or held in the buffer to eliminate disk bandwidth limitations associated with concurrently servicing any number or combination of requests, provided buffer space is sufficient. Multiple requests for continuous media data files are selectively included in groups for servicing in order to provide that buffer and disk bandwidth requirements are maintained at a minimum and within available resource capabilities.
