urther support multi-radio access, the network architecture was required to pro- vision a unified authentication framework. The support of stateless NFs, where the compute resource elements are decoupled from the storage resource elements, is intended to create a disaggregated architecture. To support low-latency services and access to local data net- works, the user-plane functions (UPFs) can be deployed close to the edge of the AN which further requires support of capability exposure and concurrent access to local and central- ized services. The combination of SDN and functional virtualization enables dynamic, flexible deployment, and on-demand scaling of NFs, which are necessary for the development of 5G mobile packet core networks. 5G network design requires a common core net- work associated with one or more ANs to be part of a network slice (e.g., fixed and mobile access within the same network slice). A network slice may include control- plane functions associated with one or more UPFs, and/or service or service-category- specific control-plane and user-plane functional pairs (e.g., user-specific multimedia application session). A device may connect to more than one slice. When a device accesses multiple network slices simultaneously, a control-plane function or a set of control-plane functions should be in common and shared among multiple network slices, and their associated resources. In order to enable different data services and requirements, the elements of the 5GC, also called NFs, have been further simplified with most of them being software-based SO that they can be adapted and scaled on a need basis. Today's static measurements of network and application performance are neither extensi- ble to the dynamic nature of SDN/NFV-based 5G networks and functionalities, nor capa- ble of creating any form of automation to create self-adapting behavior. The pace at which these environments change requires sophisticated analysis of real-time measure- ments, telemetry data, flow-based information, etc., in com
