%T Multi-Domain Orchestration for the Deployment and Management of Services on a Slice Enabled NFVI

%X This paper presents a unique and new scenario  where services are deployed across distributed domains, and  each domain MANO (for VNF Management and Orchestration)  requests and creates an on-demand Data Center slice to run  those service elements. Whilst each domain has its own MANO,  the MANOs are configured in a north-south way creating a  hierarchy of service provision capabilities, rather than configured  in the more common peer-to-peer approach. This approach works  particularly well where each domain, from the mobile edge, to the  core DC, can be managed independently of the others, but needs  to be combined to form slices. End-to-end slices across the whole  infrastructure provide a more effective resource management and  also better support the customers’ mobility requirements. The  details of the architecture to support this scenario are described.
