if you made it to this point, keep up the good work. stay focused and know that your consistency will pay off for your future career!

Who else is bringing these videos with me and taking notes?

[adanoreyes]

Making the switch from roofing contractor to IT is tough, I gotta rewatch some videos a few times to really get it, but I’m not giving up💪🏽

[Jive-]

AM i the only one that gets side-tracked every 15 seconds watching theese videos and end up watching 5min video for an hour

[OrangeSodaKing]

I'm diving into this with very limited with computer knowledge, so a lot of the content is over my head, but I find it best to watch these videos multiple times a day throughout the day, instead of cramming it all into one single session for a couple hours. That, along with looking up terms I don't know, really helps me start to gradually understand this information

Going through these videos for my COMPTIA A+. Had my first interview for an IT internship today. Wish me luck! 🙏

[AlexMaday]

Very clear and understandable description of the three planes, data control and management.

[kosmokramer]

I gotta say Prof Messer your way of explaining all of it is the best there is out there. Thank you fo rthe refresh!

[ZoltanSzaszBenedek]

I like straight forward lesson, shirt and concise. Good work ! ❤

Hey Professor, really learning a lot from this playlist so far so thank you! Just a quick question: is the network controller in an SDN a physical device or software? And how does it connect to the data layer devices in order to control them?

[OinSonOfGloin]

I need help.
Is NFV required for SDN?
What do you mean by you can separate all of the functions of the switch into individual pieces? Is the the planes, or is it function such as routing all incoming traffic to port 5 to a certain IP?
What are the benefits of SDN? Is it scalability because they are all virtual and you can just add another??
This is a good video but I get tripped up when I get asked questions about it such as: is a switch utilizing SDN virtual?
Any help is appreciated. Currently studying for Net+ 08. I have looked at many online entries on them and I still cannot complete the picture

[KeirArcher]

is the control plane like the brain and the data plane like the muscles? just trying to draw the connection this one is a bit confusing

[definitely_not_a_deepfake]

So if I'm understanding correctly, a good analogy would be like a car that drives itself.

The infrastructure layer is the engine/transmission, brake pads, drive shaft etc

The control layer would be the steering wheel, gear shifter, turn signal, gas pedal etc

And the application layer would be you with your car keys getting in and putting in coordinates, checking the oil periodically, and making sure it doesn't crash into a tree while it drives itself

If I'm too far off the mark please someone let me know! Thank you!

Basically just virtualizing the network allowing you to cut costs and improve maintainability.
