Hi,
How do you add flows in the python controller. One way to achieve this is to add using dpctl tool. I want to know if there are some inbuilt functions to call such command in python code? Also, can someone verify my understanding: After starting mininet and NOX controller, I would add initial flows using dpctl tool with a timeout say 120 secs. Now after 120 secs the flow will expire and generate flow removed event. Let us say I installed flowpath between h2 and h3 using dpctl initially. This will expire now. So any packet h2 sends to h3 will now arrive at NOX controller and controller will now decide on the flow. To resume communication between h2 and h3, controller will again set a flow between h2 and h3 again. I can use the dpctl again but is there a way to do it in python code? Regards, Kavitesh.
