The latency and flexible requirements of the 5G network are challenging telecommunication operators to have a more flexible, scalable, faster and programmable architecture. To solve this problem, this paper proposes a hybrid hierarchical set of Software Defined Networks (SDN) controllers as the control plane for 5G networks. The architecture is based on a federation of hierarchically-superior controllers which use Data Distribution Service (DDS) to communicate among each other and coordinate multiple sub-network controllers.
