Hi, Vikas your explanation with animation is really awesome. I wish you all success in your future endeavors!
Can I ask which software you use to create those wonderful animations like SDN?
Awesome explanation
Very knowledgeable content 👍👍👍👍
well explained 👍👍
Very good presentation. Please make a video about policy based security architecture for Sdn.
Very well explained 👍
Thanks for the tutorial. I have a doubt ..What about the reliability of the control plane?
Thank you, this video is clear and concise. Look at that handsome face at the end there doing the instruction. Again, good work thanks.
Very helpful video thanks sir
great explanation
Could you please explain the role of OpenStack in NFV?
Thank you Vikas !!
you are the best
Hi if SDN is down due to some technical problem will the entire network goes down. Please confirm thanks
Awesome
Thanks Sir,
Will decoupling control plane and moving it to centralized location cause a bottle neck or how feasible if network grows large?
For large scale networks , user plane has to sit near to users and control plane has to get centralized , This helps in maintaining robustness , Redundancy and resiliency of control plane nodes
This was more fun than watching avengers endgame. THanks
Thanks for this
Good one
Hello, thanks for this alike... but for everybody, this SDN/NFV is still of hype today and the real benefits much from reality yet.. So to make this happen what you see, we need to study 10x much than what we've used to so far. But one day it may work like they imagined it 10 years ago already now... And it's just hell of complicated! So you be eventually in charge of decision to transition, think it 10x over that you have the business case for it.
We need 5g call flow video related to paco,thanks
Excelent explanation! You have a subtitle of the your video? Obrigado.
You will see it soon
Great video! What application did you use to do your slides?
99% Animation & Content via - MS PowerPoint , Rest 1% Finishing from all Free Tools - Free Video Editor ( Davinci resolve ) - Free Audio Editor (Audacity) , Free Screen Capture (Activepresenter)
would you please turn on Close Caption. Thank you
ggod job
thanks for your NFV and SDN tutorial. It helped me to understand NFV and SDN in 1 hour. Btw, is OPen Flow same concept as Open Stack ?
No, OpenFlow is the standard protocol used between controllers and data plane (switches) in SDN architecture to control the forwarding tables. OpenStack is a cloud operating system to manage the cloud resources (computing, storage ..)
What is song name which is used in start of video?
It's one of Music track by Joakim Karud ... Refer below link

@@TelecomTutorialinfo ......... Congratulations to everyone for the tutorial !! .... One question only, is it possible to change the response when a request is made to a network recursive DNS Server by changing response IP to a another machine on the network (redirecting to another gateway, my network intend to put 2 gateway)? ....Thank you very much !! ...
:) .....
Wouldn’t if the router goes down, the advertisement stops and post the timer runout, the route will be removed from all router ?
I’m still confused why the centralized approach will give advantage over the current one .
I think no need to implement SDN on router. These device are already super intelligent
@@NEERAJKUMAR-eh5rn yes. SDN is good for switches.
In the beginning you have mentioned SDN is separation of brain and control plane.. in the presentation you say that the brain of sdn is control plane and sdn is separation of control and data plane..( which is actually true) i think you need to correct yourself in the beginning
Sir, can you provide your PPT?
pls do video on 4G to 5G evolution.. ONAP
Nice vikas, easy to understand VNF and SDN .. 👌👌👌 .. But I am looking to learn more about SDN suggest me.. Were I can find best information ..
Thanks in advance..
For Learning more on SDN , Try learning Generic & Open SDN controllers : OpenContrail , OpenDaylight , Floodlight etc..Then jump off to Certifications + SDN Products by key OEMs - Cisco (ACI) , Juniper (Contrail) , ALU / Nokia (Nuage) etc..
Kindly make more videos, ur explanations are brilliant :)
You will see lot of things coming soon , Thanks
@@TelecomTutorialinfo you've forget NSX-T, or simply nsx to start with.
can you give me your slide please ?
7:18 you said if D goes bad, A will never come to know. You are wrong. The way EIGRP and OSPF works, every router has the entire network topology. And if any router goes bad, the existing routers will compute new route and broadcast to entire network.
Yes, I agree on that Router are also enough intelligent for routing. There dynamic routing protocol in router which always kept update route. There internal broadcast massages to update the routing table and its also happen in few second. Many more technique ii router and switches to route the packet through best path.
Dynamic routing protocols are
RIP
IGRP
EIGRP
OSPF
Two categories. Per packet. Per flow/session. One offers both and inbound load balancing none other do (patented). Know before you buy.
India spoken
Routers update each other using RIP and OSPF protocol. This protocol will periodically update the routing tables to show the route availability status.

Watch this stuff is totally wasting my time!
