Several cashing schemes for realtime multimedia systems have been proposed but they only concentrate on the hit ratio as the performance metric without providing any means to utilize the disk bandwidth gained through cache hits. A high cache hit ratio alone does not capture the eeectiveness of a caching scheme for such systems unless hiccup-free service is guaranteed. We evaluate three caching ...
