This paper focuses on the design of a Service-BasedManagement Architecture (SBMA) that enables intelligent, crossdomain,and sustainable orchestration. SBMA adopts a servicebasedparadigm to abstract domain heterogeneity, integratesdistributed AI-driven control, and provides a foundation forachieving unified management. The proposed architecture isillustrated by mapping specific domains (such as the radioaccess (RAN), transport, and core networks) to the architecture,demonstrating how domain-specific orchestration aligns withSBMA principles and interfaces. A representative experimentvalidates the architecture’s capabilities, and the results showrapid recovery times for redeploying RAN, core, and transportcomponents, highlighting the resilience and agility of the proposedapproach.
