Transport networks for 5G will be more versatile than today and characterized by the different 5G use cases and different network architectures and also by different kinds of operator networks and different operating models. In addition to reducing latency and increasing capacity and user peak rates of the mobile network to a new level, there is a strong tendency to simplify the mobile backhaul and make it robust against failures and abnormal situations, so that mobile services run uninterrupted over the 5G transport, while minimizing transport operational needs. Security is vital as well as resiliency. With time-sensitive networking, applications rely on a common accurate time base, obtained, for example, by precision timing protocol with a profile defined in IEEE802.1AS. Low latency, ultra-reliability, and resource management with dedicated resources are addressed with specific enhancement.
