Pre-emptive but safe interval caching for real-time multimedia systems
Cashing schemes for multimedia systems proposed 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 effectiveness of a caching scheme for such systems unless hiccup-free service is guaranteed. We evaluate two caching schemes, NIC and PSIC, which make it possible to provide service to additional streams with the saved disk bandwidth.
