            Abstract : 
A virtual class delivers most of its content through multimedia learning objects. To support such multimedia learning objects, its multimedia data service system should have a capacity to serve the growing number of clients and new data. A streaming server transfers multimedia files to clients from a repository of files in real time. The server must guarantee concurrent and uninterrupted delivery of each video stream requested by clients. To provide efficient services, many stream servers adopt multi-processors, sufficient memory, and RAID or SAN in their systems. In this paper, we propose a Linux-based parallel media streaming server. This system uses a unique striping policy to distribute multimedia files into the parallel storage nodes. If a service request occurs, each storage node transmits striped files concurrently to the client. Its performance is better than the existing single media streaming service.
