Virtualized services can take benefit of statistical multiplexing across solicitations to yield momentous cost savings to the operator. However, achieving similar benefits with real-time services can be an encounter. In this paper, we pursue to lower a provider’s costs of real-time IPTV amenities through a virtualized IPTV design and through intelligent time shifting of service delivery. We take modernization of the differences in the deadlines supplementary with Live TV versus Video-on-Demand (VoD) to effectively multiplex these services. We provide a generalized framework for computing the amount of resources needed to support multiple services, without missing the deadline for any service. We construct the problem as an optimization formulation that uses a generic cost function. We consider multiple forms for the cost function (e.g., maximum, convex and concave functions) to reflect the different pricing options. The solution to this formulation gives the number of servers needed at different time instants to support these services. We implement a simple mechanism for time-shifting scheduled jobs in a simulator and study the reduction in server load using real traces from an operational IPTV network. We also show that there are interesting open problems in designing mechanisms that allow time-shifting of load in such environments.
