Design and implementation of the parallel multimedia file system based on message distribution
Seung-Ho Park, Si-Yong Park, Gwang Moon Kim, Ki-Dong Chung · 2000
The two-layered distributed clustered server architecture consisting of a control server and a group of storage servers has been widely used to support multimedia file systems. With this kind of the server architecture, it is easy to sustain disk load balancing and scalable disk bandwidth. However, it brings about the communication overhead between the control server and storage servers. Therefore, to reduce such overhead, media data should be transmitted from the storage servers to the users directly without the intervention of the control server. In addition, the file system must support the effective data placement and disk scheduling policies and should be designed to sustain portability and flexibility in any hardware or software environment to cope with rapidly developed hardware and software technologies.
