This paper presents a probabilistic model of a client/server multimedia system based on the theory of Markov processes. The server provides different qualities of service (hard real-time, soft real-time and best-effort) and is operated using a new scheduling concept based on a hybrid deterministic/probabilistic analysis. The model also provides answers to some fundamental engineering design questions related to disk price/performance tradeoffs.
