The prototype of continuous media file system, CrownFS

Currently, many multimedia or continuous media server system is under development on top of either workstations or high-end PCs clustered with high speed networking facilities. In this paper we introduce Crown, a continuous media server on clustered high performance PCs with Myrinet, fast network switching equipment, and then address CrownFS, a file system on top of Crown, to offer continuous media streams to many subscribers at the same time. For easy and rapid tuning of the performance of CrownFS, we prototyped it. Prototyping requires less efforts and costs than direct implementation. Also, more reliable system optimization is obtainable rather than simulation. By using the prototype, we measured the scalability of CrownFS according to disk access strategies
