Abstract

We study a new design strategy for the implementation of Parallel Media Servers with a predictable behavior. This strategy makes the timing properties and the quality of presentation of a set of media streams predictable. The proposed real-time scheduling approach exploits the performance of parallel environments and seems a promising method that brings the advantages of parallel computation in media servers. The proposed mechanism provides deterministic service for both Constant Bit Rate (CBR) and Variable Bit Rate (VBR) streams. A prototype implementation of the proposed parallel media server illustrates the concepts of server allocation and scheduling of continuous media streams.
