Hi all, I am a student who's interested in learning Opendaylight controller development, specifically, I just want to create a very simple controller that acts as a demo for Software Defined Networking. (can be any functions, the more basic the function, the better) I have downloaded the VM from sdnhub and followed their tutorial. However, I don't feel like this is the best environment for an absolute beginner and for my purpose stated above, as they have some sample code written. (like a learning switch?)

Any suggestions for how I should approach my task and how to set up my work environment?

Thank you!!
