SDN-based architecture to support Synchronization in a 5G framework

Network synchronization is expected to be one of the key aspects in 5G. This article presents an application of the SDN (Software Defined Networking) and NFV (Network Function Virtualization) principles to the area of the network synchronization, enabling to offer synchronization as a service. The approach is based on defining a harmonization layer that allows orchestrating radio and heterogeneous transport domains.
