Reinforcement Learning for Slicing in a 5G Flexible RAN Open
Network slicing enables an infrastructure provider (InP) to support heterogeneous 5G services over a common platform (i.e., by creating a customized slice for each service). Once in operation, slices can be dynamically scaled up/down to ma…

Dynamic Slicing Approach for Multi-Tenant 5G Transport Networks [Invited] Open
Software defined networking allows network providers to share their physical network (PN) among multiple tenants by means of network slicing, where several virtual networks (VNs) are provisioned on top of the physical one. In this scenario…
