Agile management of 5G core network based on SDN/NFV technology

In the 5G era, radio IP capacity is expected to reach 20 Gbit/s per sector, and ultra-large content traffic will travel across the faster wireless/wireline access network and packet core network. Also massive and mission-critical IoT is the main differentiator of 5G services. These types of real-time and large-bandwidth consuming services require radio latency of less than 1ms, and end-to-end latency of less than a few ms. By distributing 5G core nodes closer to cell sites, backhaul traffic volume and latency can be significantly reduced by having mobile devices downloading content immediately from a closer content server. In this paper, we propose a novel solution based on SDN (Software Defined Network) and NFV (Network Function Virtualization) technology in order to achieve an agile management of distributed 5G core network functionalities and services with PoC implementation targeted for Pyungchang Winter Olympics.
