SlicedRAN: Service-Aware Network Slicing Framework for 5G Radio Access Networks

5G mobile networks are envisioned to substantiate new vertical services with diverse performance requirements. Slicing in the radio access network (RAN) promises an efficient solution for these diversified needs of networks, which foresees separation base station functionality between central unit (CU) and distributed remote heads. In this article, we formulate a mixed integer programming (MIP) framework that maximizes throughput by jointly selecting optimal functional split routing path from connected user equipment CU, while satisfying agreed service level agreements (SLAs) each service. Furthermore, propose effective heuristic, SlicedRAN, creates isolated RAN slices premised on requirements through fronthaul/backhaul (FH/BH) obtains near-optimal solutions short computing time compared MIP framework. Our results show there is tradeoff architecture FH/BH minimum SLA slice, provides efficiently design virtualized infrastructure. According results, SlicedRAN outperforms existing state-of-the-art up 112% gain throughput. Results shown close loss below 5%.
