Caching in Flat Mobile Networks: Design and Experimental Analysis

Mobile network operators are aiming at strategies to accommodate the expected huge traffic growth with limited impact on the core network load. Enhancing the mobile architecture, along with deploying content delivery networks, represent promising areas where operators are putting their efforts to reduce costs while meeting the service guarantees. In this article we present a novel mobile architecture for 5G networks which benefits from the joint design of distributed mobility management and mobile video content delivery networks. We first discuss the architectural aspects of this combination and then present our validation and performance results from a real Linux-based prototype implementation.
