Optimal Slice Allocation in 5G Core Networks

Network slicing is the key to providing flexible, scalable and on-demand solutions for the vast array of applications in 5G networks. Two key challenges of 5G networks are the network slicing and guaranteeing end-to-end delay for a slice. In this paper, we address the question of optimal allocation of a slice in 5G core networks. We adopt and extend the work by D. Dietrich et al. [1] to create a model that satisfies constraints on end-to-end delay as well as isolation between components of a slice for reliability. Our work takes into consideration Service Level Agreement and performance parameters. Our results show the impact of varying parameters on the utilization of the system.
