Abstract:
Management and Orchestration (M&O) are essential activities in 5G slicing systems. Essentially, the integrated M&O based on The European Telecommunications Standards Institute (ETSI) Management and Orchestration (MANO) is the basis, but enriched, in order to cope with slicing. In particular, supporting technologies like Network Function Virtualization (NFV) and Software Defined Networks (SDN) are considered, to deliver functional components for 5G slicing M&O. The multi-tenant, multi-domain, multi-operator, end-to-end (E2E) features of the 5G slicing determine a high complexity for M&O. Consequently, many different architectural variants have been already proposed, studied and developed in recent studies, standards and projects. The study in this paper is useful because, despite many efforts, (spent in the last five years) much heterogeneity and different solutions still exist, even at the M&O architectural level. This paper analyzes the existing common parts and differences between several 5G slicing architectures, in an attempt to identify a degree of “convergence”, while considering the MANO as a base architecture.
