Abstract

Abstract— This document is a solution for the Video On Demand Case Study in order to determine the number of servers to attend all requests per hour in a VOD center. This paper models requests on a Video on Demand (VOD) Center in order to minimize the cost function of weighted number of servers of each type with some constrains such as the availability of bandwidth, total available servers for the VOD service, the cost of turning on and off a server, and the total number of servers on or off at the beginning of the ith hour. Once the model is developed and Service Level is established in order to add complexity to the model, a simulation is run to verify assumptions and sensitivity of the objective function.

Index Terms—video on demand centre, simulation, requests on data centres, modelling data centres, energy conservation.
