However, the advantages of network slicing come at the price of higher complexity in operating and managing telecom networks. To cope with such complexity, the ETSI zero-Touch network and service management (ZSM) framework is designed as a next-generation management system that aims to ideally have all operational processes and tasks executed automatically. ETSI has defined a procedure to deploy the network-slice-As-A-service (NSaaS) scenario using the ZSM reference architecture. Two important use-cases for a more ambitious NSaaS model are MANO-As-A-service (MANOaaS) and heterogeneous MANO-As-A-service (H-MANOaaS), where multiple instances of the same (MANOaaS) or different (H-MANOaaS) MANO frameworks are deployed over the same physical substrate. We propose a conceptual model for supporting the never-Addressed H-MANOaaS use-case. We also offer a blueprint to integrate the MANOaaS and H-MANOaaS use-cases into the ZSM procedures and mechanisms. We then validate the H-MANOaaS deployment use-case with a proof-of-concept where our proposed solution is instantiated using a real-world slice-As-A-service platform and some relevant implementations of different MANO frameworks. date: 2024-06 date_type: published publisher: Institute of Electrical and Electronics Engineers (IEEE) official_url: http://dx.doi.org/10.1109/mcomstd.0001.2100088 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2283823 doi: 10.1109/MCOMSTD.0001.2100088 lyricists_name: Clayman, Stuart lyricists_id: SCLAY98 actors_name: Clayman, Stuart actors_id: SCLAY98 actors_role: owner full_text_status: public publication: IEEE Communications Standards Magazine volume: 8 number: 2 pagerange: 4-11 citation: Correa, SL; Contreras, LM; Dias, EV; Furtado, LR; Cunha, KMR; Xavier, RF; Freitas, LA; ...
