Actuation Framework for 5G-Enabled Network Slices with QoE/QoS Guarantees

Network slicing is identified as the enabling technology for efficient service delivery in future 5G networks. Moreover, a key aspect in 5G network slicing relates to the delivery and maintenance of QoS/QoE guarantees for the provisioned slices. This paper discusses an overall framework for coordinating and orchestrating the proper actuations to restore the provisioned end-to-end network slices requirements. In particular, a policy-based actuation system is adopted, where a policy framework applies policies tied to specific behaviours. Such policies, that may trigger configurations in the different segments of the infrastructure, are aimed to maintain or restore the QoS/QoE requirements of the slice.
