Abstract:
Management and orchestration functionalities are crucial activities in 5G slicing systems. Essentially, the basis is the integrated framework Management and Orchestration (MANO), of The European Telecommunications Standards Institute but enriched, in order to cope with slicing. In particular, supporting technologies like Network Function Virtualization and Software Defined Networks are considered, to deliver functional components, cooperating for 5G slicing management and orchestration. The multi-tenant, multi-domain, multi-operator, end-to-end features of the 5G slicing determine a high complexity for management and orchestration. Consequently, many different architectural variants have been already proposed, studied and developed in recent studies, standards and projects. This study is useful because, despite many efforts (spent in the last five years), much heterogeneity and different solutions still exist, even at the management and orchestration architectural level. However, the MANO is considered as a base starting point architecture. This paper is an extension of a previous study. It analyzes in more depth the existing common parts, differences and heterogeneity of several management and orchestration 5G slicing architectures, identifying the similar functionalities and also the factors leading to heterogeneity.
