I. Introduction
Network Slicing concept was first conceived by a standardization body, NGMN [5] later that considered being the key enablers in the next fifth-generation (5G) networking. NFV has emerged with possible approaches to support for an open network [1], it allows service providers to become more flexible. The NFV architecture supports bottom-up hierarchy to support vertical services and the combination of SDN, NFV enables trends for the network softwarization [2]. 5G networks aim to achieve various QoS in a possible network scenario in terms of latency and throughput [3].
