Executive summary
The 5G-PPP vision towards the next-generation networks & services, offering ubiquitous and performant access in line with the different service needs, comes with a set of requirements that span across the infrastructure and management domains, including performance, dynamicity, and programmability. In this context, management and orchestration become very important features for enabling the correct support for verticals. Different classes of 5G services must be orchestrated on top of 5G infrastructures that come with different capabilities and different exported network functions, while considering concepts such as virtualization and software driven, programmable capabilities. Rather than setting up and managing services in network domains separately and manually, the expectation of 5G networks is that cross-domain E2E services will be provisioned, deployed, managed, and retired in a DevOps manner, with minimal manual intervention. In addition, where slicing capabilities are exposed by network domains, those E2E services will be deployable on network slices and managed accordingly.
