Effective delivery of Virtual Class on Parallel Media Stream Server

Abstract

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 an 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. 1.
