I. Introduction
Fifth generation mobile networks (5G) are being explored to serve diverse traffic domains. The complex network traffic demands are leveraged by cloud and edge computing. 5G proposed three application scenarios: ultra-high reliability and ultra-low latency communication (URLLC), enhanced mobile broadband (eMBB) and massive machine-type communication (mMTC). Software Defined Networking (SDN) and Network Function Virtualization (NFV) is used by 5G networks to meet growing on-demand network services. SDN and NFV reduces the operational costs of the network operators with the programmability of the existing network infrastructure. High spectral requirement is strigent criteria for eMBB, uRLLC is dependent on high reliability and low latency. The broadband service of 4G is extended as eMBB. It supports high data rate with stable connection for large payload. It provides moderate reliability with error rate in the order of [1]. For less payload mMTC can be used with which supports large collections of Internet of Things (IoT) devices. URLLC also referred as mission critical communication that accepts low latency and high reliability for smaller payloads.
