Realization of 5G Network Slicing Using Open Source Softwares

With the advent of 5G, billions of devices use the 5G radio access network. Network slicing is a fundamental architecture component of the 5G. End-to-end network slicing leverages the attributes of central virtualization technology in 5G to flexibly address. In this paper we realize the network slicing using OpenStack as a cloud platform, Tacker to manage the required virtual network functions for each service and OpenFlow switch for slice. We also apply OpenFlow Queue command to schedule the priority and proportion of each service. Finally, the actual implementation is carried out via OpenAirInterface and nextEPC. Experimental results show that the network slicing is feasible using open sources and the bandwidth can be assigned using queue. As a result, the QoS is guaranteed for each slice.
