IEEE Transactions on Wireless Communications.1536-1276https://hdl.handle.net/10016/31399In Press / En PrensaNetwork Slicing is expected to become a game changer in the upcoming 5G networks and beyond, enlarging the telecom business ecosystem through still-unexplored vertical industry profits. This implies that heterogeneous service level agreements (SLAs) must be guaranteed per slice given the multitude of predefined requirements. In this paper, we pioneer a novel radio slicing orchestration solution that simultaneously provides latency and throughput guarantees in a multi-tenancy environment. Leveraging on a solid mathematical framework, we exploit the exploration-vs-exploitation paradigm by means of a multi-armed-bandit-based (MAB) orchestrator, LACO, that makes adaptive resource slicing decisions with no prior knowledge on the traffic demand or channel quality statistics. As opposed to traditional MAB methods that are blind to the underlying system, LACO relies on system structure information to expedite decisions. After a preliminary simulations campaign empirically proving the validness of our solution, we provide a robust implementation of LACO using off-the-shelf equipment to fully emulate realistic network conditions: near-optimal results within affordable computational time are measured when LACO is in place.15engThis article is an open access article distributed under the terms and conditions of the Creative Commons Attribution (CC BY) license.Atribución 3.0 España5G and beyondVirtualizationMABLatency controlNetwork slicingResource managementresearch articleTelecomunicacioneshttps://doi.org/10.1109/TWC.2020.3027963open accessIEEE Transactions on Wireless Communications
