Supporting 5G service orchestration with formal verification

The 5G communication technology has the ability to create logical networks, called network slices, which are specifically carved serve particular application domains. Due mix of different criticality, it becomes crucial verify if applications? service level agreements met. In this paper, we propose a novel framework for modeling and verifying orchestration, considering simultaneous access admission new requests slices as well virtual function scheduling routing. By combining in userfriendly UML, with UPPAAL model checking satisfiability-modulo-theories based finding, our supports both formal verification orchestration. We demonstrate approach on e-health case study showing how user, no knowledge methods, can system UML that meets its requirements.
