چکیده
Advances in networking and storage technologie.; have made it possible to build multimedia on-demand servers that provide service similar to those of neighhorhood videotape rental stores. In this work. we p p o s e a speciaiized high-perforniance programmable multiprocessor architecture which allows continuous playback of mediastreams to large number of clients, a critical factor in multimedia servers. This architecture supports dynamic phase shifts in media distrihution which i s particularly useful i n a distributed environment. We introduce dlgorithnis for inaximiiin concurrency extraction and to avoid task rnigration in thr pi-esence of dynamically changinp dernand. We show th:ir our solution perforins an order of n ~ ~ ~ r ~ i t u d e better than other known solutionh.

متن کاملAdaptive Load Sharing in Video-On-Demand Distributed Multimedia System Using Parallel Servers
This Video data is stored in a video server for delivery to multiple receivers over a communications network in a traditional video-on-demand system. The hardware in this video server has the following limitations: 1) the maximum storage capacity, and 2) the maximum number of video sessions that can simultaneously be delivered. We propose a novel Adaptive-Multiple-VIdeo-Server -Architecture (AM...
