Abstract
AbstractA specific feature of the 5G systems is the ability to serve very different industry needs by satisfying their specific requirements in a single network. A wide range of services can be simultaneously offered by the same 5G network, thanks to the deployment logical end‐to‐end network slices on a common infrastructure. All the domains of a telecommunication network, i.e. access, transport and core network, are touched upon by the architectural solution to support end‐to‐end network slicing (of which core and transport are covered in this article). Each of the mentioned domains evolved in the last few years to define and provide the key technologies enablers, described in the article, to reach the level of dynamicity and flexibility promised by 5G network slicing. Management and orchestration layer also needed to evolve in order to support the features necessary to integrate the core and transport network domains to provide a real end‐to‐end architecture.
