Below are two options that you can explore for modelling the networking components of your system in Simulink:
- "SimEvents" is an add-on for Simulink that allows you to model discrete-event systems, including networks, queues, and communication channels. You can model components like routers, switches, and network delays using this. “SimEvents” does not have explicit “firewall” blocks, but you can build custom logic to simulate firewall behaviour (e.g., blocking or allowing packets based on some rules)
- You can also create your own firewall or router models using basic Simulink blocks such as the ‘Function Blocks’
