Popularity and prefix aware interval caching for multimedia streaming servers
Oh‐Hoon Kwon, Hyokyung Bahn, Kern Koh · 2008
With the recent proliferation of video-on-demand services, caching in a multimedia streaming server is becoming increasingly important. Previous studies have shown that request interval based caching and its extension for considering different video popularity performs well for various streaming environments. In this paper, we show that the incorporation of prefix-aware caching into the existing schemes can further improve the performance of streaming servers. Trace driven simulations with real world VOD traces have shown that the proposed scheme improves the performance of multimedia streaming servers significantly in terms of the cache miss rate and the startup latency.
