A research on VNF-enabled radio access network for UDN using low-cost compute node

The Network architecture using the deployment of VNF (Virtual Network Function) based on NFV (Network Functions Virtualization) enables to provide fast service to the user, since it has flexible structure in mobile traffic. In this paper, we propose the network configuration scheme capable of VNF deployment through low-cost compute node for the small cell such as 5G UDN (Ultra Dense Network). In addition to, we describe the network architecture without the special settings and connection. By using resource utilization test, we demonstrate an ability of the proposed network architecture.
