3. Introduction to SDN (Software defined network) - SDN and Openflow Architecture

[@changweihsu]

I've been watching videos of SDN for a while and this is obviously the best one. Very good structure and easy to understand. Thanks and thumbs up!

[@mathew729]

FINALLY! Someone that understands how to explain the SDN concept for people that don't already understand it! Terrific overview...it finally clicked for me! Thanks!

[@Switchbladejohny]

Great overview crammed into 18 minutes - nicely done!

[@manasi1962]

Thanks a lot for explaining NFV and SDN concepts in such a simplified way. Both SDN & NFV content or coverage is really wonderful!! Thank you once again.

God bless you Sir for sharing information of software

[@renjithmp777]

supper :-) , most of the "What is SD-WAN" is marketing related video from vendors. your simplified and detailed explanation is awesome.

Watched the entire series! Really helpful. Good work

[@bilalaslan5047]

Great video, thanks for your time and effort

[@faizali3895]

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.

[@NEERAJKUMAR-eh5rn]

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

[@bshimekit]

A quick and easy one. It's Awesome.

[@parishuangelsworld2207]

its very intresting and explained with very simple manner. we are expecting more videos on Cloud

[@arunarora81]

thanks vikas, for coming up something so well explained, with animation crisp audio, excellent to the point information. wish you success in your all endeavour

[@sanjeetbajwa5026]

very clearly explained. Since am not from telecom domain but still got a hang of things. Great job!

[@jimdozer999]

Thank you, this video is clear and concise. Look at that handsome face at the end there doing the instruction. Again, good work thanks.

[@arjunraghav007]

Will decoupling control plane and moving it to centralized location cause a bottle neck or how feasible if network grows large?

[@TelecomTutorialinfo]

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

[@shrirama1150]

Thank you very much for this tutorials, truly helped me to understand the basics very clearly as i'm beginner. Thank you again.

[@PankajKumar-sm7ee]

Very knowledgeable content 👍👍👍👍

[@CanYoCan]

Great lecture, I like the way you have explained the concepts, Thanks a lot. Keep it up

[@Sathyaanarayanan]

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 .

[@NEERAJKUMAR-eh5rn]

I think no need to implement SDN on router. These device are already super intelligent

[@Sathyaanarayanan]

@@NEERAJKUMAR-eh5rn yes. SDN is good for switches.

[@utkarshshukla1735]

Many applause for this effort. 🙏🏼 Thank you.

[@emreyavuz4706]

Thx Vikas very clear and basic explanation. Impressed the key differences very well. Also documenting is great.

@@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 !! ... :) .....

[@sandappan]

Well articulated. Many thanks.

Very good presentation. Please make a video about policy based security architecture for Sdn.

[@vishals9353]

Simply Excellent

[@abhijitkarkare]

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

[@mamidalaradhakrishna8738]

Hi if SDN is down due to some technical problem will the entire network goes down. Please confirm thanks

[@CloudBatais]

well explained 👍👍

[@rafaelperezdelacalle1526]

Hi Vikas, great work!! congrats!!

Great and clear explanation for SDN~ I got the initial image on that and try to go deep, Thx for video👍👍

[@neytan55510]

This is great! Thank you

[@peterg91]

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.

great explanation

[@manikantpedapati]

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..

[@TelecomTutorialinfo]

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..

[@pulkitgargpec]

Kindly make more videos, ur explanations are brilliant :)

[@TelecomTutorialinfo]

You will see lot of things coming soon , Thanks

pls do video on 4G to 5G evolution.. ONAP

[@arsulaksono881]

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 ?

[@ibrahemmhmd2521]

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 ..)

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?

[@skippwhipple6632]

Two categories. Per packet. Per flow/session. One offers both and inbound load balancing none other do (patented). Know before you buy.

Routers update each other using RIP and OSPF protocol. This protocol will periodically update the routing tables to show the route availability status.
