Abstract:	Many modern telecommunications systems rely on strict timing and synchronization requirements. Synchronous Ethernet (SyncE) and Precision Time Protocol (PTP) are widely used to provide frequency and phase synchronization in current 4G and future 5G backhaul and core networks. This paper describes how the synchronization capabilities provided by these two technologies can be managed as a service following the SDN/NFV paradigm, thus opening the way for a virtualized syncronization control plane in 5G core and access networks.
