Abstract

In this work, we investigate cache placement strategies for layered video content. We consider a library of video files that can be requested in different quality levels, according to a specific distribution. The study involves formulating and solving two distinct optimization problems to determine the most effective approach to cache placement. Our aim is to compare the following strategies: placement strategy which reduces congestion on the backhaul link by minimizing the number of transmissions necessary to meet user requests, and placement strategy which maximizes the probability of users being fully served from cached content. As shown in the solutions, these two performance metrics lead to different solutions for content that needs to be cached.
