Аннотация

There’s a need to secure the paradigm of software-defined networks for many reasons, and one of the methods proposed in our research is to use Petri Nets system to model some proposed working topologies for the SDN controllers; those topologies were also proposed in our research to secure some aspects of the SDN paradigm. After modelling the suggested SDN controller topologies, it is possible to imply that modelling in the PIPE software to get simulation results. Those results could be used to derive a security equation to measure the security level of any network that’s based on the SDN structure and leveraging any of the three proposed topologies in our research. In this paper we’ll concentrate on modelling the third and last proposed topology which is the Hybrid topology and compare it with the single-controller already existing topology that we named the Ordinary topology. The comparison will show the feasibility of the Hybrid topology and its advantageous effect over the Ordinary topology. Keywords: Blockchain, GSPN, hydra, Hybrid topology, Petri Nets, RSA, virtual private network.
