I am doing a project in omnet++. I connected the network to a SDN controller However I like to know how to get subgraphs of routers in a SDN network.

Define Network Topology: First, define your network topology in OMNeT++ using modules to represent routers, switches, SDN controller, and connections between them. You can use the INET Framework in OMNeT++ to create network topologies easily. Identify SDN Controller Connections: Within your network topology, identify the connections between routers and the SDN controller. You can define parameters or attributes in your router modules to indicate whether they are connected to the SDN controller. Traverse the Network Topology: Implement logic in your OMNeT++ simulation model to traverse the network topology and identify routers that are connected to the SDN controller. You can use algorithms like Depth-First Search (DFS) or Breadth-First Search (BFS) to explore the network and identify connected routers. Create Subgraph: As you traverse the network and identify routers connected to the SDN controller, create a subgraph data structure (e.g., a list, vector, or graph data structure) to store these routers. Visualize the Subgraph: If you want to visualize the subgraph of routers connected to the SDN controller, you can use visualization tools in OMNeT++ or export the subgraph data to external visualization tools for better representation. Analyze the Subgraph: Once you have the subgraph of routers connected to the SDN controller, you can perform further analysis or simulations on this subset of the network to study their behavior or performance.
In OMNeT++, you can create a subgraph of routers that are connected to an SDN (Software-Defined Networking) controller in a network topology by implementing the necessary logic in your simulation model. Here are the general steps you can follow to achieve this:
By following these steps and implementing the necessary logic in your OMNeT++ simulation model, you can create a subgraph of routers that are connected to an SDN controller in a network topology and analyze their interactions within the network.
