In this paper, we describe its operation and discuss mechanisms that are tailored to the efficient verification of nested-models. Further, we motivate the advantages of N-PAT over traditional model-checking tools through a network security case study.application/pdfen-AU© Springer Nature Switzerland AG 2020202010.1007/978-3-030-51054-1_222022-10-02
