In a video server environment, some video objects (e.g., movies) are very large and are read sequentially. Hence it is not economical to cache the entire object. However, caching random fractious of a multimedia object is not beneficial. Therefore, traditional cache management policies such as LRU are not effective. The sequential access of pages can be exploited by caching only the intervals between two successive streams on the same object, i.e., by retaining the pages brought in by a stream for reuse by a closely following ...
