Title
Optimal Content Delivery With Network Coding
Abstract
We present a unified linear program formulation for optimal content delivery in content delivery networks (CDNs), taking into account various costs and constraints associated with content dissemination from the origin server to storage nodes, data storage, and the eventual fetching of content from storage nodes by end users. Our formulation can be used to achieve a variety of performance goals and system behavior, including the bounding of fetch delay, load balancing, and robustness against node and are failures. Simulation results suggest that our formulation performs significantly better than the traditional minimum k-median formulation for the delivery of multi I pie content, even under modest circumstances (small network, few objects, low storage budget, low dissemination costs).
