Function Splitting, Isolation, and Placement Trade-Offs in Network Slicing

We model the network slice provisioning as an optimization problem including novel mapping and requirements rising with new radio core function placement policies. propose open-access framework based on MILP formulation that encompasses flexible functional splitting, possibly different splitting for slices subnets, while taking into account sharing policies from 5G specifications. also consider continuity constraints specific to architectures beyond. show by numerical simulations impact of full partial consideration these peculiar technical constraints.
