Even a person with no IT background will easily understand this with the way you explain, Eli! Thank you so much 😊

I watched this video yesterday and had a job interview today. The IT manager asked me about "the future of IT" so I gave him a little lesson on SDN, should have seen the look on his face. Thanks ELI!

I was in the military and was trained in an Air Force technical school about all of this back in 2003. The course covered more than you can imagine. This video would have been handy for my exams back then too. Great refresher! Thanks Eli!

I couldn't stand writing a comment here ! --04/21/2018-- Got all my introduction courses in one 1 week from Eli. Great explanation with great real life examples ! Best place to learn networking. Thanks.

This guy is just such a great instructor!!! Thank you man.

exactly, I wish there were more stuff regarding networking from Eli. Well, if you read this message, I kindly ask you to continue this sets of videos regarding networking and put into your playlist. you're a great instructor.

Started looking at it and has been only a couple of days, this was the best explanation I have yet found! Cheers Eli! Awesome work

I'm amazed by how long ago this video was released. Its 2021 and SDN is still considered "bleeding edge tech". And you just made it much easier to conceptualize.

I love the way this guy just repeats the same information over and over again on every video he does.

I was lagging in understanding until he said there's a psycho in the building. Now thats practical teaching.

I actually donno a thing about SDN but you made it so easy for me !!

Awesome video, nice way to introduce SDN with historic references.. loved it!

Over three years since you recorded this and my professor asked me to research about SDNs. This video was a great starting point!

I don't see that option in any of my configurations..?

You are an amazing educator. Thank you for producing these videos!

Great explanation Eli, thank you. For a person working at one of those networking companies you mentioned, your method of explaining SDN provides great clarity on what it is and is not.

Best explanation on KZread about SDNs!

Excellent explanation. This gentlemen made me understand SDN, after several attempts. I salute you Eli.

Great video Eli! One of the best introductions of SDN

Thanks Eli! Wish my university textbook could have been as clear as you were on this.

Thank you so much , you are the BEST ! Its time we have you on a mobile app :)

After 7 years, Still a great video. you Just injected very effectively

So clearly so basically, a great instructor. Thank you

Things enter from eyes and fit into brain really fast !! you explain the best !! best instructor on the internet !!

God! Such a beautiful explanation, Thank you very much! Greetings From Brazil!

While it’s true that Software Defined Networks (SDNs) continue to grow and get the majority of the buzz in the news these days, another technology called Application Defined Networks (ADNs) is starting to make its presence known in the business world as well and it has the potential to really take off. Based on what I know about Application Defined Networks (ADNs) this technology has the ability to fill some of the gaps that Software Defined Networks (SDNs) present. Application Defined Networks (ADNs) and Software Defined Networks (SDNs) are both based on similar concepts but solve separate ends of a complex problem. Application Defined Networks (ADNs) allow enterprises to securely reach and consume economic benefits of cloud services, where Software Defined Networks (SDNs) are resident. Software Defined Networks (SDNs) primary focus is inside the data center to allow for greater dynamic allocation of network resources to deal with spikes in resource demands. Software Defined Networks (SDNs) have not addressed the complex task of facilitating secure access to the cloud data centers faced by multi-site enterprises. Application Defined Networks (ADNs) primary focus is virtualizing the edge of the data center creating secure access to the cloud services. Application Defined Networks (ADNs) focus on the millions of brick and mortar enterprise locations need to resolve the core security, performance, and reliability conflicts that are limiting application expansion to data centers. For the purposes of my comment, an application can basically be defined by a business need and may include things like payment, loyalty, guest access Wi-Fi, point-of-sale support, tank monitoring, etc. In short, an Application Defined Network (ADN) simplifies security by establishing discrete independent networks that do not require complex security rules to partition traffic types. It is designed so that specific security and performance policies can be established at the application level versus the network interface level which allows for applications with contrasting security policy requirements to be completely isolated from one another and facilitated with customized security features. It eliminates the need for new application specific devices to securely petition discrete application networks and eliminates future capital costs. If an Application Defined Network (ADN) is breached by an outside party, the ability of the breach to bleed between applications is virtually eliminated due to each application having customized security and performance policies. After comparing both of these technologies, I feel that Application Defined Networks (ADNs) have an advantage over Software Defined Networks (SDNs) simply because Software Defined Networks (SDNs) have not addressed the complex task of facilitating secure access to the cloud or data centers for multi-site enterprises. Most businesses today have multiple locations over a large geographic area and this is exactly what Application Defined Networks (ADNs) are designed to handle.

Thank you for the explanation , i found that SDN use the mechanism of microsegmentation for high security , i'm a beginner in this subject, i m wondering if i can get your email to contact you concerning this issues,thanks again

I have been searching for a proper explanation of SDN , but each time end up with Bookish terms in other videos. Here you come... Now understood the exact meaning of these 3 letters :) Thank you for sharing the info in such a simpler manner. Clap clap for you....

Thx you kind sir! Your videos are very very good. I recommended them to my last boss. Honestly, you're the only reason why I was able to keep that job. Thank s again for all your hard work

Thank you very much Eli, it is exactly the introduction I was searching for ;)

This was recorded in 2013! Great video, Thank you!!!

Thank you Computer Guy for updating our brains .

You have a cool name btw.

What I like about your videos, is that you give rreal point of view of some one who does a complete different work from me. It's almost every time interesting at least for that sake.

I really appreciate the way you explained this. very clear. Nice work!

It's a cool presentation on SDN introduction. Many thanks Eli !

Some great information in here. Thanks for taking the time to put it together.

Awesome way of explaining.. You are blessed with Teaching skills.. Thanks.

Thank you Eli. Great introduction on Software Defined Networking!

Thanks Eli As always clear description You open the new horizon in my knowledge area

all your videos are really instructfull, thanks for all the work you doing

Thanks Eli. You make a very clear introduction about SDN.

This is a really nice video and the way of explaining things is simply awesome. Thanks Eli.

good job !! my lecturer was rubbish to explain it ! you are always very useful ! Thanks from UK

Thank you for providing vendor neutral information about SDN since everyone else often defines this subject in terms of their own narrow focus and profit motives.

This video is pretty good also. I can definitely see a use for SDNs in the Armed Services. In a Mission Command node, it's very important to allocate the right amount of bandwidth to make sure all the services we use are running smooth. This is actually a very common problem we still have today. If you get a chance, do a quick search for WIN-T and what the DoD is trying to get accomplished by the year 2025. Thanks again.

Wow! Absolutely amazing and brilliant explanation!

What a great explanation. Thank You Eli.

You explained what SDN is, really well. Thanks.👍

Nope... The main concept behind SDN is that you separate the Data Plane from the Control Plane... So that the intelligence resides on "servers" that send instructions down to the Networking equipment...

Well done. Thanks Eli, best I have seen in type of easy to understand the Idea.

Thanks sooooooo much!!! Learned a lot!!! Your speaking is really clearly!! It’s easier for me to get what you said.

It's quite interesting to see how networking is developing ..SDNs will make major shift in the networking model .

thanks again Eli! your the man!

Thanks Eli. You are THE BEST!!!!

Eli, Thanks so much for this video, I really appreciate you sharing your knowledge.
