The resources placement problem in a 5G hierarchical SDN control plane

Abstract

In this paper, we address the SDN Controllers and Virtual Network Functions (VNFs) placement problem in 5G networks. To this aim, we propose an architecture for the 5G Control Plane and a method to determine the optimal placement of controllers and VNFs. The placement is determined according not only to latency and capacity requirements but also to type of Network Function (NF).
