Effects of Traffic Reshaping on Distributed Video-on-Demand Systems

In this paper we analyze the effect of reshaping traffic using various network service disciplines on Videoon-Demand (VoD) applications. Using a client centric approach we develop a methodology based on a realtime producer-consumer framework. We present an anlytical model of client buffer requirements in presence of network delay bounds and delay jitter bounds. We show through numerical analysis that controlling delay jitter not only reduces buffer requirements but also provides the option of accomodating heterogenous clients with different buffer sizes for the same server transmission schedule.
