It’s been a while, isn’t? As I have nothing better to share with you guys and I have not posted for a long, I decided to put something here that may guide you, if you are new in SDN or it may also be used as a shortcut for elemental documets for people who are already working on SDN.
So, that’s all,
(Unfortunately, I don’t have nothing better to post here, right now. 😦 )
