Software-defined transport provides the basis for 5G network slicing
5G network slicing empowers communication service providers (CSPs) to offer a new suite of differentiated services featuring on-demand, customer controlled self-service options. A network slice is an end to end, logically separate network partition with unique network performance and latency characteristics to serve a particular use case or enterprise.
To deliver true network slicing, CSPs need a cross-domain network slice orchestration architecture that stitches together domain-level slices to form an end-to-end slice spanning the RAN, edge, transport, and the core network domains. In the architecture implemented by Telefonica iFUSION, the software-defined transport network (SDTN) controller is used to provide the domain-level slice management capability.
