Abstract:
Multi-domain and end-to-end (E2E) capabilities are major objectives in 5G slicing. A split is needed of the multi-domain slice capabilities between several technological and/or administrative domains while still preserving their individual independency. Admission control is also necessary when a new multi-domain slice is requested by an user/tenant, i.e., during the slice preparation and instantiation phase or at run-time when slice instances scaling is needed. The above tasks are solved by the Management and Orchestration (M&O) system for services, slices and resources (physical or virtual). The M&O is performed at two scopes (global and local in each domain) and can be organized using several layers depending on the business model (actors) considered. This paper contribution consists in the proposal and analysis of several architectural solutions to organize the domain-level management for a network segment of a multi-domain slice. In particular, the functions splitting and interactions among the layers of the domain management are studied in the context of Network Function Virtualization (NFV) and Software Defined Networks (SDN), technologies used in the system architecture.
