Load sharing based on popularity in distributed video on demand systems

In recent years, there has been an increasing interest in video on demand (VoD) systems. We study a distributed VoD system in which the videos are replicated according to their popularity. We present an algorithm to share the load in such a system efficiently and an analytical model that captures the performance of this algorithm, which we validate through simulations. This research shows that popularity is an essential parameter which can save storage without reducing performance by just replicating a few popular videos in all the servers.
