A middleware architecture for QoE provisioning in Mobile Networks

This paper presents the design of the CASPER
¹
middleware architecture that enables the implementation of real-time QoE-driven service management. More in detail, we thoroughly describe the new modules, methods and functionalities that need to be integrated into the network providers' infrastructure, according to CASPER. Based on this architecture, future virtualized networks can provide a closed-loop feedback environment that can act autonomously to maintain high levels of QoE with minimal human intervention. This is achieved via the proposed “QoE orchestrator”, which is responsible for implementing the QoE related logic.
