thms are proposed for slice recovery and reconfigura- tion under stochastic demands. This is followed by an in-depth assessment of the failure rate, average load of substrate attainable with the presented algorithm. Finally, a tradeoff between the robustness of slices and the average load of the links is established, which can be efficiently managed and controlled. In Chapter 11, a flexible function split over ethernet for enabling RAN slicing in future networks is described. The chapter starts by introducing Cloud-RAN as one of the enablers of 5G. It then introduces functional split to Cloud-RAN with a more flexible placement of baseband functionality. This is then followed by a description of the fronthaul reliability and slicing when multipath is deployed at the fronthaul. Then the flexible functional split and the multipath packet-based fronthaul for RAN slicing are evaluated via both experimental and numerical results. Chapter 12 discusses service-oriented RAN support of network slicing to meet different key performance indicators (KPIs) for different vertical services. The chapter starts by pre- senting the general concept and principles of service-oriented RAN slicing. The chapter then describes the RAN system deployment scenarios, namely deployments on a single fre- quency band, deployment over multifrequency bands, and hybrid deployment. This chapter also introduces key technologies enabling service-oriented RAN slicing. In Chapter 13, 5G network slicing principles and enabling technologies for the V2X ecosystem are discussed. The chapter introduces the current and future V2X applications and the related requirements, together with the available V2X communication technolo- gies, with a focus on the latest progress in the 3GPP and concerning radio interfaces and architecture design. The emerging segment routing technology is also investigated as further facilitator of network slicing for V2X communications. Furthermore, the chapter summarizes the main lessons learnt from research and development activitie
