SDN based operator assisted offloading platform for multi-controller 5G networks

This paper presents an operator-assisted data offloading platform for 5G mobile networks by using Software Defined Networking (SDN). By enabling lateral communication between multiple SDN controllers, operators are able to perform the offloading process without the intervention of the user. Moreover, the offloading decision of proposed platform is based on accurate real time network conditions. The proposed mechanism is implemented on a testbed to verify feasibility and performance.
