When you succeed teaching a concept to a person who is not an SME of the subject being taught, then you know the teacher is insanely awesome. Thank you David.
Thank you. I'm a Technical Director looking at this technology for the first time, and found it confusing until this video kicked me in the right direction.
This video is an excellent way to get introduced to the SDN concept,i really appreciate the time that you took to put this presentations together and also to highlight the excellent pace you used on your videos to explain concepts like SDN, your videos have helped me to continue increasing my knowledge of the networks like NFV, SDN, IoT and 5G.
Thanks so much for the detailed feedback! I'm glad you commented on pacing because on a couple of my other videos there are comments that I spoke/went too fast. I was able to compare this video to those and see that in fact I have starting speeding up since this video - and should not have done that ;-). Thanks!
This is a very well executed presentation, David. I tend to be critical of on-line video presentations, as the illustrations and paired audio are either too light on content and abbreviated (revealing a lack of knowledge on the part of the presenter) or too detailed on specifics rather than presenting context and awareness (too convoluted). This was well balanced and professionally delivered!
.... Congratulations on the tutorial, David + 1 like here !! ....Please , one question only, is it possible to change the response when a request is made to a network recursive DNS Server, changing response IP to IP from another machine on the network (redirecting to another gateway, my network intend to put 2 gateway)? ....Thanks alot !! ...
David, your videos on OpenFlow and SDN have been an eye opener for me and are helping me greatly in my graduation paper. Really well put videos, informative and easy to understand. After these its easier to understand the very dry documentation.
Excellent video on SDN. It's a great video David. Thanks for sharing such a valuable information. Exited to see how this will implemented in real world
Thanks for your video, i am newbie and i want to get started on SDN, openswitch your videos make an eye opener for me and get a broader picture. Thanks a lot !!
In less than an hour, you finally made me understand the concept of SDN, introduced me to mininet and showed me the first steps with Openvswitch. Thanks! And well done. You talk very fast. Is this good or bad? I had to pay attention very closely, which is not a bad thing at all, but after that hour I was really tired. Try making a slower video; I will then tell you which is better :)
David, thanks so much for this video. It has helped me a great deal. I hope you make more videos. I have one request: Please speak slower. It's difficult to understand new information, especially when someone speaks fast. But this is still a great video.
Thank you so much David. Subscribed and followed on LinkedIn. Keep it up with this great job of helping most of us. This was simply the best introductory video about SDN. Being a graduate student in Electrical and Computer Engineering with telecommunications and computer networks as my major. My area of interest is SDN and NFV. I wish to commence a major project in SDN to get an in depth knowledge and understanding about the subject but with SDN and NFV technologies evolving rapidly at industrial level as compared to university level, it is not easy to catch up. Can you help me with some good project ideas related to SDN. My key skills include routing and switching protocols, Linux, Bash scripting, C++ and Python. My motive is to simulate a network using open flow protocol which utilizes all the 3 layers you explained (Application, Control and data plane) and could demonstrate the capabilities of SDN, analyze the performance measures of the network (Latency, throughput, delay etc).What controller is best suited for my skills? How to integrate application layer ( supposing I'm a data center or an enterprise) with the control plane? Other recommended software?
Hello Sandeep. Thanks so much for your comments. I really think a great jumping off point is the IEEE article I reference in the video - there are so many ideas and areas covered there - it also discusses a lot of your questions and references a ton of great research so you can see what's been done, what controllers are being used, etc. If you want to discuss more, hit me up on linkedin. arxiv.org/abs/1406.0440
Great video. Concrete example are helpful for me (perhaps others, too). For instance could you name some specific network applications, or specific forwarding devices? For me, such examples help to provide a tangible context, which enhances retention. Once again, thanks for a great vid.
Want to know what is the future of SDN? I don't want to know that this is the future but if anyone can actually tell me is SDN the Next Real Thing and why? Will there be no other technology that can out-stand the concept of this SDN?
Woaaa nice video with simple and clear understanding, thanks for the video ! I have one question for you, have you try to implement this technology (SDN) in a campus network ?
Hello sir Your videos are are very informative. I want to proceed my research with SDN. Want to know that is there any place where SDN is practically used. Thank you

Very kind feedback Kashif, thanks for that!
your 13 min video has explained me the SDN concept. short, precise ...excellent.
Thank you. I'm a Technical Director looking at this technology for the first time, and found it confusing until this video kicked me in the right direction.
Great! That's what I was hoping for with the video, some kind of head start.
This is an excellent presentation. No fluffy nonsense, just straight into the detail. Great.
I dislike fluffy nonsense ;-). Thanks for the comment and feedback!
Easily the best video on SDN I've seen - you cleared up so many points that other videos I've watched failed to cover. Thank you for uploading this.
That's awesome, thanks for taking the time out to comment and give feedback!
Sir you are a living legend. Thanks for your description.
So nice of you

Simplicity is sensibility, nice work David (y)
arpit desai Thanks a lot!
I'm an SDN Controller software engineer. It's helpful. This video has explained SDN concept clearly, precise.
Nice, thank you William! Glad to not get called out by an expert ;-).
After reading and watching a lot of videos, your's was the one i needed to finally understand SDN concept. Thanks!
You're welcome!
Excellent....

Thanks! I've heard that feedback before, it is hard to find a balance but there is some consensus I should slow down a little :-). Will work on it.

Want to know what is the future of SDN?
I don't want to know that this is the future but if anyone can actually tell me is SDN the Next Real Thing and why?
Will there be no other technology that can out-stand the concept of this SDN?
Thanks, well put together !!
