Our target is to characterize the additional bandwidth that servers must supply to immediately satisfy all requests to watch a given video. We develop an approximate fluid model to compute the required server bandwidth in the sequential delivery case, as well as in controlled nonsequential swarms. Our approach is able to capture several stochastic effects related to peer churn, upload bandwidth heterogeneity, and non-stationary traffic conditions, which have not been documented or analyzed before. Finally, we provide important hints for the design of efficient peer-assisted VoD systems under server capacity constraints. EXISTING SYSTEM: THE efficient distribution of video contents will be one of the main challenges of the future Internet. According to Cisco forecasts, the combination of all forms of video (live streaming, video-on-demand, and P2P file sharing) will be in the range of 80 to 90 percent of global consumer Internet traffic by 2017, posing a tremendous challenge to both content providers and network operators. In particular, Video-On-Demand traffic has been increasing tremendously during the last few years. the wide popularity gained by existing applications, several fundamental questions remain unansweredabout the design of

Indeed, the unpredictable nature of users cooperation, that cannot always guarantee the strict quality-of-service requirements of online video; the added complexity on the control plane due to signalling and chunk scheduling; and the need to provide incentive mechanisms to the users, tend to discourage the content providers to adopt peer-assisted solutions. PRPOPOSED SYSTEM: We have proposed a computationally-efficient methodology to analytically estimate the server bandwidth requested in non-stationary peer-assisted VoD systems. Our approach is highly flexible, and can account for several important effects such as peer upload bandwidth heterogeneity, churning, non-sequential chunk delivery schemes. Finally, we provide important hints for the design of efficient peer-assisted VoD systems under server capacity constraints. CONCLUSION: We have proposed a computationally-efficient methodologyto analytically estimate the server bandwidth requested in non-stationary peer-assisted VoD systems. Our approach is highly flexible, and can account for several important effects such as peer upload bandwidth heterogeneity, churning, non-sequential chunk delivery schemes. We have shown that our analysis provides efficient, accurate predictions of all observed phenomena, providing a useful tool for the design of peer-assisted VoD systems.
