5G/6G network slicing is identified as key enabler technology for allowing a diversity of sustainable applications while satisfying user’s requirements. A major problem of the traditional networking technologies is the use of the ”one size fits all” approach that handles all types of services. In this work, we focus on drawing a new architecture born of the need of a multi-level services’ orchestration for seeking flexible intelligent management of the new generation use-cases such as massively deployed cloud and edge-cloud based IoT applications for (i) environment monitoring, (ii) Agriculture development, (iii) and new generation Augmented Reality applications in medicine or e-learning.Thispaperproposesanovelmulti-levelDelegationArchitecture for Network Slicing Orchestration (DANSO). DANSO proposes a multi-level delegation for slices management and optimization framework for resources allocation. Our proposal is based on three pillars: (i) definition of levels to fulfill support of network slicing deployment and management via delegated decisions (ii) split of orchestrator, manager and control roles and (iii) placement-independence of entities in (ii). DANSO has the following advantages. First, it provides an optimization mechanism for the deployment of network slices. second, it takes into consideration a negotiation process for the requested slice. Third, it manages the life-cycle not only for the Virtual Network Function (VNF) level but also for the dynamic deployment and suppression of the whole slices. last, it considers network slicing over several administrative domains. |
