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.
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!
Eli, it is now 2015. How about an update and include Arista Networks in the mix. Also, what software did you use for the whiteboard portion of your youtube video?
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...
Nice, hack the control plane you have the whole network! SDN specific attack worldwide...imagine. 25,000 Linux servers worldwide have been hacked recently even though the Linux community is the most powerful open source community. SDN is will be obliterated by hackers. Cisco IOS always being hacked. Let's just channel smtp traffic a but then funnel it back, hey wait a minute, the control plane will be a way to capture keystrokes! Can you imagine a centralized place to capture all keystrokes of a network....eureka!!! Or will it be not?.....stay tuned.
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.
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!
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
This is much bigger... Such as Cisco and Juniper are building API's so that applications can actually have direct control over the network... At InterOp they were talking about the horror of literally having something Farmville be able to directly control network traffic... Google "Cisco ONE"
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.
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.
seriously u r really cool man, keep on the hard work i've read alot about SDN (didn't really get a thing) almost half way though your video and i got the idea thanks alot dude :)
Hi Eli, How would change control work if the IT manager wants to change config of the network at any time ? ... I have some experience working with centrally configured and managed network which actually can be reconfigured with few clicks. But there is change controls in place to prevent some IT person making a mistake and bringing down the whole network down :-)
So eli are you more in favor of SDN's than parallel networking techniques/methods? What about simple QOS? As of this moment, what is the best solution for huge corporate networks with a hefty need of balancing bandwidth?
When you separate the data and control plane, what about the latency? Much, if not all is nowadays done in hardware, in software it would be too slow. Is the data plane still using the ASIC's? But are programmed by the control plane which is just a collection of software and communication protocols? So in other words, the control plane isn't involved in routing or QoS decisions in real-time. It only reprograms the data plane and thus the ASIC's? Is that correct? Because if all the decision making is done in software, how would that be progress compared to the speed of a pure ASIC implementation?
2) SDN controls the devices in the cloud, it is not for corporatives, so the robber example is out of reality. The delivery problems occur in big networks where the latency and jitter are critical. Some examples are online games, collaborative in engineering where people has to control remote devices, a remote surgery, etc. Another classic example, a virtual store, where people try clothes and be attended by a seller. This kind of example exist today but the experience is not good enough.
This video has many misunderstandings. 1) SDN is a solution for telcos. You will never have the control of the network, unless you would be a telco. The telco will give you the broadband and you or your applications decides which one are more latency sensitive. Today if you configure the parameters of quality of service on your router nothing will happend, because you haven't hired a VPN's service. But it is only for companies. SDN will allow telcos sell this kind of service in a massive way.
I understand the concept of SDN and it is interesting, but nothing new. This is basically how Wireless LAN Controllers work when using lightweight access points. It will be interesting to take this approach with routers and switches. Also, I wasn't too crazy with the SDN example about HiDef video clogging the network. If you were multicasting this video to all of your end-users, 1 or 1000 recipients of the video stream would not clog the network...because it's multicast.
this seems to me to be similar to Cisco software on things like catalyst 6500 series etc where the supervisor is separated and the network is tightly controlled for the network and the Unified Network architecture is this similar or a simpler version for SOHO /SB use? especially some of the newer stuff i have seen in there VOIP stuff (doing same sort of stuff as your angry wife example) thanks for the video
3) In 1999 there were solutions like that, but Cisco bet for a cheaper solution, MPLS, in order to gain market and wait for a better moment. In those day VoIP already existed, also video conferences. I agree SDN separates control from hardware and this will allow run more complex applications over IP networks.
second is i recent reformatted two hard drive to use as back up memory for my gaming system, but for some reason now when i try to plug it into the computer now it wont allow me to open it, it will show in the devices menu but i cant open it. please if you have any idea on a solution i would greatly appreciate it, thanks for your time.
please help ,I am in packet core like ,worked on LTE . but now all things going on Virtualizition ,I am worried now where should I start to catch this transformation ,
You say there is no central view for SDN. But its look like the big IT company’s has put their heads together with opendaylight (look up the website). (juniper, cisco, brocade, Microsoft) So hopefully the basic SDN will be the same. But only vendor specific functions will be differed
Hi Eli, Where SDN gets a bit unclear is around virtualization technology vendors and their involvement in orchestration of network policies to create a single view on both the physical and virtual components of networks. Can you help clarify this?
thats wierd... Khan academy and other accounts have that option. Well, if you have time you should look it up but only if you have time. It's not a crucial feature anyway. Just beneficial. Thank you for your time!
Reminds me of the tourist in France who thinks the local person can understand him if he speaks slowly and more loudly. Probably I should have said Italy because of the hand motions...
first is i need to do a "wipe & reload" on a asus eee pc 100peb, only thing is i dont know how to do it with out a cd drive. have your done a video on this type of situation using a usb?
For Large Networks like telecom you would not want your controllers to be centralized. Any hiccup in that central area and your network is gone. This is going to be mostly for huge data centers and even in the Data Center you would want two controllers atleast.
Eli the Computer Guy Not sure if you've seen this talk on the future of networking and end of protocols The Future of Networking, and the Past of Protocols - Scott Shenker
I never understand SDN, it is kind of centralising stuff. And centralising stuff is never better in large networks. Basically the SDN controller becomes a new bottle neck, single point of failure, ... its like going backwards.
No . SDN controller is for policy or configuration changes. it stores the configuration of network and push relevant configuration to networking equipment (Switches,Router etc) .it does not matter if controller goes down. network will work fine because network equipment already has configuration required for its working (which stores locally i.e. control plane). Redundant controller is recommended for high availability but not required .
Good stuff, thanks Eli! I'm actually looking for a SDN architect to join our team in Omaha, NE. We handled 58 BILLION minutes last year alone and want to deploy an SDN strategy in the very short term. Any questions? Please ask!
🙏🙏🙏 Hats of Eli, really amazing to see the way you explain any concept. The way I want anything to be explained, in a perfect way with ground set strong to actually understand the concept well. Best ever basic video of SDN. Can you do some new videos relevant to today's time. Once again, thank you so much.
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....
Well here we are about a year later and it seems that the forementioned heavy hitters have formed a consortium around OpenDaylight with its Hydrogen release having a Service Abstraction Layer that separates it from the OpenFlow-centric platforms.
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.
Hey Eli, Brilliant video buddy. One question, but before that some background. I've worked as a SDE on many Network and Device management Softwares for THE software giant in the industry. That giant has been increasingly focusing on the management part of the network and the respective devices just like any of the industry players of today. Do you see Openflow being integrated/hooked with the existing applications of various networking companies? Will Openflow evolve into something like that?
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.
Even a person with no IT background will easily understand this with the way you explain, Eli!
Thank you so much 😊
15:49 This took a bit of a dark turn...
U
HAhahahah
murica
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!
Eli, it is now 2015. How about an update and include Arista Networks in the mix.
Also, what software did you use for the whiteboard portion of your youtube video?
The software looked like Microsoft OneNote... I might be wrong.
Duude whiteboard is nice but please try to write in a more readable fashion - but great video
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...
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
Nice, hack the control plane you have the whole network!
SDN specific attack worldwide...imagine.
25,000 Linux servers worldwide have been hacked recently even though the Linux community is the most powerful open source community.
SDN is will be obliterated by hackers.
Cisco IOS always being hacked.
Let's just channel smtp traffic a but then funnel it back, hey wait a minute, the control plane will be a way to capture keystrokes!
Can you imagine a centralized place to capture all keystrokes of a network....eureka!!!
Or will it be not?.....stay tuned.
just my initial thoughts too, ... :-)
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.
because of you it's easy to comprehend a JARGON words.
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!

Keith Richmond awesome man! even in 2017!... I want to save this comment somehow.
"Application Defined Networks (ADNs) allow enterprises to securely reach and consume economic benefits of cloud services" Citation needed
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
Awesome video, nice way to introduce SDN with historic references.. loved it!
Thanks Eli! Wish my university textbook could have been as clear as you were on this.
God! Such a beautiful explanation, Thank you very much!
Greetings From Brazil!
This is much bigger... Such as Cisco and Juniper are building API's so that applications can actually have direct control over the network... At InterOp they were talking about the horror of literally having something Farmville be able to directly control network traffic... Google "Cisco ONE"
I actually donno a thing about SDN but you made it so easy for me !!
Awesome way of explaining.. You are blessed with Teaching skills.. Thanks.
You are an amazing educator. Thank you for producing these videos!
It's quite interesting to see how networking is developing ..SDNs will make major shift in the networking model .
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.
Excellent introduction to SDN. Thank you Eli. Please prepare a video session for "Open Stack" if possible
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.

Thanks again.
all your videos are really instructfull, thanks for all the work you doing
seriously u r really cool man, keep on the hard work
i've read alot about SDN (didn't really get a thing)
almost half way though your video and i got the idea
thanks alot dude :)
I don't see that option in any of my configurations..?
So clearly so basically, a great instructor. Thank you
Thank you so much , you are the BEST ! Its time we have you on a mobile app :)
Hey Eli,
All your videos are great. Many thanks. can you please also explain the Network Virtualization?
Sorry.... What did you say jitter is?
thanks again Eli! your the man!
Thank you Computer Guy for updating our brains .
You have a cool name btw.
Very good Tutorial, provides the fundamentals with clarity. Thanks.
So what is the state of SDN now, that it is 3 years later from the video?
+Grivier2 I would like to know the same. I am wondering if someone here have more information about SDN-present
Hi Eli, How would change control work if the IT manager wants to change config of the network at any time ? ... I have some experience working with centrally configured and managed network which actually can be reconfigured with few clicks.

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

thanks for the video
Great video Eli! One of the best introductions of SDN
Finally understood SDN...…. please share the difference between SDN and NFV.
7:54 had me wiping and blowing on that hair for ten seconds
Good video and explanations... example of shooter in the building didn't make sense though. Otherwise, helpful.
3) In 1999 there were solutions like that, but Cisco bet for a cheaper solution, MPLS, in order to gain market and wait for a better moment. In those day VoIP already existed, also video conferences.

but now all things going on Virtualizition ,I am worried now where should I start to catch this transformation ,
Whut

Very good Tutorial, provides the fundamentals with clarity. Thanks
It's freakishly American to use a school shooting as an example for SDN... What a sad and dark indictment
thats wierd... Khan academy and other accounts have that option. Well, if you have time you should look it up but only if you have time. It's not a crucial feature anyway. Just beneficial. Thank you for your time!
Reminds me of the tourist in France who thinks the local person can understand him if he speaks slowly and more loudly. Probably I should have said Italy because of the hand motions...
Hehehe Oh America. 0^0 Casualty mentioning school shootings as a real world every day occurrence.
first is i need to do a "wipe & reload" on a asus eee pc 100peb, only thing is i dont know how to do it with out a cd drive. have your done a video on this type of situation using a usb?

Whoa you were getting into computers in 1999?? You look way younger
Eli the Computer Guy Not sure if you've seen this talk on the future of networking and end of protocols The Future of Networking, and the Past of Protocols - Scott Shenker
Eli, can you please enable the option to increase the playback spped of your future videos once you have the time please? Thank you for your videos.
He says don't worry it wont be deployed in 2-3 years.. in 2013.. its now 2018... Sh*t
Eli..good explanation but the question now is what is going to happen to network engineers and security pros...less need or more need of them?
Great info as usual Eli, but perhaps you can make pre-set slides for your videos...my 4 year old niece writes better than that. Just saying
Can u help me pls? I have a modem huawei smartax 882 and i want to create a ts3 server but i cant because i have to open ports forwarding
Eli i don't know .... I have modern Belkin router. In the QoS profile i have the Auto QoS. So its the same like SDN thing
Really Helpful.. Thanks a lot!!
why does he talk like that.... is he ok? ...eli...try to enunciate a little harder..you don't look ridiculous enough.
SDN will also improve dynamic routing ( the choice to chose the best route to get to the destination faster)
I was lagging in understanding until he said there's a psycho in the building. Now thats practical teaching.
Very succinctly put.. Thanks for the information..
Awesome idea, but doesn't it make it easier to hack the infrustructure?
Nice introduction , but a question , what is the present of SDN now ?? i mean it is been three years has anything changed ?
Juniper already have the control and data planes systems architecture. SRX and M and T series.
I truly hope that this is not a real world example of why SDN is valuable.
So UDP based protocols where the solutions for RTC at 6:00
I am not an IT person but this short video is awesome. Would appreciate an update soon?
I never understand SDN, it is kind of centralising stuff. And centralising stuff is never better in large networks. Basically the SDN controller becomes a new bottle neck, single point of failure, ... its like going backwards.

Redundant controller is recommended for high availability but not required .
I am an IT student that wants to do a big project on SDN. Any ideas on how to go about that?
CAN YOU PLEASE HAVE A CLASS ON MICROSOFT MANAGEMENT CONSOLE (MMC)..
Good stuff, thanks Eli! I'm actually looking for a SDN architect to join our team in Omaha, NE. We handled 58 BILLION minutes last year alone and want to deploy an SDN strategy in the very short term. Any questions? Please ask!
🙏🙏🙏 Hats of Eli, really amazing to see the way you explain any concept. The way I want anything to be explained, in a perfect way with ground set strong to actually understand the concept well. Best ever basic video of SDN. Can you do some new videos relevant to today's time. Once again, thank you so much.
Why can't we do this type of on the fly QoS with current hardware?
Couple his jaw with a dynamo and you get infinite power.
can we implement VLAN using SDN????
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....
Awesome video on SDNs. Now I'm pretty clear what SDN is.. Thanks Eli..
Nice discussion on SDN. Thanks for it.
But it was hard for me to ignore the fact that Eli looks more like Jason Statham :)
Don't you Eli? ;-)
Thanks for the explanation
Absolutely awesome explain on software defined networking. Good start for me!!! Thanks
good job !! my lecturer was rubbish to explain it ! you are always very useful ! Thanks from UK
what are the different services (like firewall) which is referred in the video?
Well here we are about a year later and it seems that the forementioned heavy hitters have formed a consortium around OpenDaylight with its Hydrogen release having a Service Abstraction Layer that separates it from the OpenFlow-centric platforms.
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.
thank you very mmuch for your video.. this help me a lot understanding SDN. wish me luck to my interview :D
Thanks for the explanation, it was perfect
Hey Eli, Brilliant video buddy. One question, but before that some background. I've worked as a SDE on many Network and Device management Softwares for THE software giant in the industry. That giant has been increasingly focusing on the management part of the network and the respective devices just like any of the industry players of today. Do you see Openflow being integrated/hooked with the existing applications of various networking companies? Will Openflow evolve into something like that?
This was recorded in 2013! Great video, Thank you!!!
