When the controller receives FTQ, how does it calculate the path? Is it the Dijkstra algorithm?

When I switched to the directory _/examples / SDN / conttoller_ and executed the make instruction, an error occurred.

Does this project have anything to do with μSDN mentioned in this article?

Hi,
Do the green lines specify the control flow and blue lines the data flow?
The problem is that the green lines are always pointed to node 1. Can't we have multiple controllers? Can the controller be any node other than node 1?

Hello!

I had a question as I have been consulting both repositories about uSDN, and it is not clear to me. It would be great if you could give me some guidance on this 😄

From what I've been seeing there are two uSDN repositories:

• This one, which has the uSDN source code base and has Contiki support.
• This other one, which is being progressively ported from the uSDN source code base to Contiki-NG.

Is this correct? Thank you!
