Clustering system is getting popular in various application areas because of its cost-effectiveness. In this paper, we introduce the CROWN (Clustering Resources on Workstations’ Network) system that consists of several PCs interconnected with the Myrinet. In order to provide multimedia-on-demand services, especially V oD, we have developed the CrownFS as a continuous media file system over the Linux operating system. The CrownFS is a userlevel file system. Because the clustering technology is based on offthe-shelf commodities, user-level design and implementation can be natural in clustering system and has a great benefit in portability. The architecture of CrownFS and its usage for VoD service are presented in this paper. As the result of the field test, the VoD server built up with four nodes prototype system of CrownFS can provide 150 MPEG-1 streams concurrently. CrownFS can also be extended to support discrete media file system and to provide over thousands multimedia strea...
