UDP doesn't suck! It's the BEST L4 protocol for THESE types of applications...

[@PracticalNetworking]

📺🧩 TCP Masterclass: kzbin.info/aero/PLIFyRwBY_4bS-PQZoF0UySdG0sH9VA0bn 🚨📢 Announcement: *I'm creating a full Networking course!* Details --> pracnet.net/networking 📺🕸 Module 1 of the course is *free* : kzbin.info/aero/PLIFyRwBY_4bRLmKfP1KnZA6rZbRHtxmXi But what about the TCP Masterclass? I have about 10-12 lessons scoped out for a comprehensive TCP Masterclass, and I'd love to create it at some point. When I released the first three lessons, I offered a challenge: If any one video garnered 100k views in the first 6 months, I would create the full TCP Masterclass. Unfortunately, we didn't meet that goal, so I had to prioritize other projects. But I haven't given up hope! *If you are interested in seeing the full TCP Masterclass developed, then the best way to bring that to fruition is to spread the word about this content*. Doing so will help others fully understand TCP and UDP and bring me closer to committing to creating the full series... Plus, think of all the Internet Points you can get for sharing this series (likes, karma, follows, etc) 😉 If you share this series, please use this link: kzbin.info/aero/PLIFyRwBY_4bS-PQZoF0UySdG0sH9VA0bn Otherwise, I genuinely hope you got a lot out of the first three lessons. Thank you for all the encouraging words in the comments. =)

[@anilaxsus6376]

how is the Network course coming along ?

[@EstebanDuPlantiers]

Ed Harmoush is the Absolute Olympian of explaining the theory of Computer Networking, the practical details, the logic, the subtleties, the preconceptions, the errors. Everything. Wonderful, mesmerizing work, congratulations! ❤

[@PracticalNetworking]

Thank you for the kind words, Esteban. Cheers.

[@NeurosesGamer]

It's not much Ed, but I'm glad to have found you at the beginning of my career into Networking and Cybersecurity. Additionally, I'm sure, that in the future after I hopefully and eventually land my first job and beyond, I will be sharing with others how great of a teacher this Ed Harmoush guy on KZbin is lol. Keep making these videos, they are amazing!

[@Abdirahmaann]

Good luck Neuroses

Ed., you're a bundle of blessings. I can't thank you enough for all you give. You carry the burden of making these technicalities meaningful without being asked. I don't even know how to describe you. You're simply awesome. This production is always getting better; I feel like there's no limits to your resourcefulness. Beyond the technologies, your visuals and audio blends are just just just beautiful. Thank you.

[@Abdirahmaann]

These two protocols tcp / udp played a very important role in technology last 40 years

[@dpi3]

only tutorial series that justifies the "masterclass" tag, it truly is! 💥

[@PracticalNetworking]

[@NeurosesGamer]

Ed I have been consuming your content religiously, thank you so much for your time. I had just watched your TCP video a couple days back, and you dropped this at the perfect time 😆

[@PawanKumar-Ravish]

Thanks Ed , Your content is awesome , i can't believe this all can be explained in such a easy way .

[@cyantarek5457]

This is the best video ever or TCP vs UDP with live examples and visual explanation. You earned a sub!

[@zvonimirlevacic1531]

Many thanks for the excellent content, Ed!

[@PracticalNetworking]

Thank you for supportin the channel, Zvonimir. You are helping direclty contribute to the production of more training content for everyone else. Thank you again. Cheers!

[@dypsking3414]

Hi, I just want you to know that after watching one of your video i was so satisfied. I visited your channel, subscribed, browsed through all your contents and downloaded all the videos in 'Networking Fundamentals'... You did a very good job. BTW thanks for all that. 💯💥

[@scottspa74]

Apparently I really need to see what you come up with for a QUIC lesson, because despite looking into it a bit, and looking at the structure and fields of QUIC, I still understood it to be a L4 protocol unto itself (even though it utilizes UDP); nothing I read led me to understand QUIC as an application layer protocol. So apparently I need to re-investigate. One of your breakdowns with illustrations will certainly shed more light, if you get a chance and are so inclined. 😄 Thanks for the great content! It really makes such a difference !

[@SaumyaAgarwal-j5g]

I watched the complete playlist of Networking Fundamentals. You explained so well. Thankyou😊

[@rghazzi]

Thanks!

[@PracticalNetworking]

Hi Rghazzi! Thank you so much for supporting the channel with your super thanks. You are directly funding the continued creation of content like this =). Much appreciated, thank you again! ... and you're very welcome =)

[@khanget]

The only video I have seen that explains UDP how it should be explained .... Thanks a Ton you have done an amazing job

[@riggle74]

Ed, more excellent content! I work on the OT side and UDP has several good applications. First, UDP works perfectly for historical process data that needs to go through a data diode. Second, real-time control data that relies on

[@0eieiei]

I had never thought about this concept. Thanks for the knowledge!

[@pbrigham]

Almost everything will be migrating to QUIC, you should make a video on that, love yours channel, please keep up.

[@utkarsh_s28]

Amazing content. Gripping as a thriller movie! Please keep on posting such tutorial videos.

[@MvrouaneCissp]

i want to tank you for this series of video is great thing you colect all this information of networking fundementals in just 16 video + others .i repeat a video when i don't understand somthing in The basic networking and in futur if i forgot this informition i will rewatch your videos . Good content man keep going and Allah bless you❤🙏

[@k.alipardhan6957]

unlike other videos which were recap of the basic are studied in highschool days haha, this is actully helpful... I'm prepping for SDE 3

[@PracticalNetworking]

Good luck with the SDE3 interviews =)

[@pcbona]

Not that im not interested in a TCP masterclass, but there is already alot of information about TCP and UDP out there. It would be great to do a quic masterclass, as there is not alot of deep dive (like your TLS course that i enjoyed very much) on that topic yet.

[@pepeshopping]

It’s all out there. Don’t wait for a KZbinr if you want to learn something.

[@pcbona]

@@pepeshopping do you have any? I tried getting a quic masterclass, but there is only a wireshak deepdive for it that does not cover all topics on it (no conguestion control for example)

[@wwolfram33]

Another fantastic learning session. Thanks!

[@PracticalNetworking]

You're very welcome. Thank you for supporting the channel.

[@mgpindian5083]

Excellent explanation around the UDP. Thanks mate❤

[@dustcore]

Great explanation and video Ed, be cool to see a video on Quic in the future as well.

[@burnzism]

Great explanation, clear and consice.

[@cslb38]

Very nice Job Ed, I have learned more UDP today and I know the gaming world wld suck if not for UDP, it simply allows the live gaming all across the globe and a few packet burst here and there isn't a big deal. I'm still blasting your links every single chance I get on Reddit especcially when mentioned subnetting as you were a godsend for myself and I wish to tell everyone possible.

[@steposka]

I think another good candidate for example that works better with UDP is VPN. Thanks to your videos I understand why WireGuard uses UDP. Because it essentially creates virtual wires between computers on the internet. And the communication going through VPN is using the best protocol for its needs. If the VPN used TCP and the members of the VPN also used TCP, if packet was missed, both VPN and the application would do TCP countermeasures resulting in chaos..

[@amitpatil1900]

Very easy to understand and informative too, Thank you Ed!!

[@ajidaniel8818]

Loved that voip packet loss demonstration lol

[@adnaneafifi1450]

Yaay ! a new introduction =)

[@PankajMane-f9v]

All your videos are really helpful, could you please create a video regarding TCP port. means their importance and all the major port numbers.

[@SuperLittleTyke]

I use a Visual Basic 6 program I wrote several years ago to copy the contents of the clipboard on one PC to the clipboard on another PC on the home network. It uses UDP. I looked at similar programs on the internet, but none did quite what I wanted, and writing my own program enabled me to enhance it whenever I needed. There have been several enhancements over the past six years or so. The program works on XP, Windows 7 and Windows 10. UDP is easy to understand.

[@electrowizard2658]

man u explain so smooth

[@worldfac1s]

All these make sense. Thank you

[@rghazzi]

I 'm not sure why you don't already have a million subscriber.

[@alexisroux2448]

maybe because youtube favors quantity over quality

[@geerliglecluse5297]

Crystal clear explanation, thank you!

[@PracticalNetworking]

You're very welcome!

[@herteert299]

You are the best teacher. Thank you

[@davidmcken]

Good content, I do take a bit of issue with the 2nd category though. Almost every protocol that implements their own built in confirmation system at best re-implements TCP (usually the better ones fall in the 3rd category of acceptable levels of loss / ignoring packets that are too old) or at worst give a false sense of security that the transfer completed successfully. I kinda put it in the category of "Don't roll your own crypto" For your example of TFTP that re-transmission system now limits the file size to 4GB (pre-1998, the original spec only allowed 32MB), also the primary place I either use or have seen TFTP which is transferring software images to routers every device that supports it also has a verification to MD5 (or other checksum) the file to ensure the file arrived to that router correctly. Normal SNMP I'm fine with as to me that falls more in category 1 than 2 (small message / small reply, not worth the extra work for TCP and if you don't get a reply just ask again just like DNS). However, SNMP traps to me falls in the same boat as syslog. While I can see a potential use for sending a last "dying gasp" message the majority of the time the receiver has no clue that a message has gone missing. It makes it very unreliable in practice as the issue can only be detected by independently checking the logs or more commonly when an incident occurs (be it service affecting or security-wise) the warning for which was lost. Syslog actually has a message id field but it is seldom filled in (and your receiver has to keep track of the missing sequence numbers) and SNMP has no such field. My specific issue with those poor implementations comes from one of the streaming protocols MPEG-TS, which has a 4-bit (you read that right, 16 possible values for a sequence number) which when put together with the fact that it works only in complete lock step where if packet #13 arrives pico seconds behind packet #14 it will be treated as if it never arrived. These protocols break under the simplest of redundancy applications like bonding multiple links together without some specific consideration given to them. QUIC is also a bit of an oddball, it really should be a fully fledged transport protocol alongside TCP and UDP but sitting somewhere along the spectrum between them (I would put it 3/4 along closer to TCP). The google engineers themselves said as much but they implemented it on UDP to allow it to pass over current networks with no modification required save the end points. Even then they are still finding outdated / mis-configured devices blocking it.

[@ManishYadav0719]

Before I start watching any video by Ed, I used to first like, share and comments ❤

[@acluster3411]

So well done! How about dissecting the Ethernet/IP protocol and Wan Technologies?

[@lexkenn]

Thanks for the video! Highly appreciate it

[@olegasgolubevas8773]

The content is awesome! Thanks

[@PracticalNetworking]

Glad you enjoy it. Thank you for supporting the channel.

[@MFoster392]

Love your work you're a great teacher

[@fabrizioCivetta]

I can confirm 100%. Tcp add only problems for for application that have already a flow control and use small packets. Connection, socket in time wait state, manage correct the disconnection. Allways better use the brain instead of simply follow the standards. 😁👍

[@nadid5347]

Top Top Top Great cours. Thank you sooo much Ed.

[@JavedEnginer]

Excellent content

[@omarM2023]

Amazing Explanation TY

[@50calpoptart84]

Awesome Video!

[@Madsycode]

Great work! Stay blessed

[@HH-hy8ph]

I’d like to learn more about Quic.

[@akivaSk]

I would tell you a UDP joke, but you wouldn't get it.

[@PracticalNetworking]

😉

[@IliyaDamyanov]

Very informative video.

[@leetanizer]

thanks for the excellent video !

[@vikasbedi82]

UDP is awesome, TCP is awesome, networking is awesome, Ed is awesome, everything is awesome.

[@mikenelson1495]

Thanks. I've a better understanding.

[@jaafarbalaghi9012]

Great 👏👏👌

[@masoodhosseinifard4178]

Thank you very much!

[@raymondtunmbi9168]

honestly, i just wanna TIP you. awesome job

[@Rigre-i1u]

I prefer the faster more unreliable one... which so far has been pretty reliable.

[@code-inc]

Web 3.0 use Quic which is based on udp :)

[@mq6033]

If syslog is being used to send log events, perhaps critical log events, maybe better to use tcp instead of udp?

[@Abdirahmaann]

Ed can you add traceroute command uses udp packet to reach the destination if didn’t get target you will get unreachable destination

[@Ajju1992]

Thank you Sir

[@fazeltanha-i6v]

thank you very much you are explaining very well too much

[@Velo1010]

But do the network choose which protocols (UDP or TCP) it will use to communicate with the host/server?

[@ahadrandhawa83]

what about Wireless sensor network, shouid I prefere TCP or UDP

[@gvs75tx]

Thanks

[@adtv_breaking_of_theprinciples]

I want to learn all protocols in what subjects do all come ??

[@cuspajzz]

Great ! Thx 😀

[@TheUrbanGeekinTECH]

Great Information, Thanks for sharing!

[@zouhairsouam6709]

Hello ED, thank you for this informative Video. what if you explain the vxlan, evpn .. ? i think they will have more views.

[@Duriel1000]

How do I change the protocol of my application from tcp to uDP or vice versa? Sorry if that is a dumb question.

[@pepeshopping]

UDP is king for fast, short, quick data transfers (as long as you don’t have a big round trip or high packet loss).

[@telisijohn2054]

@PracticalNetworking, can RTP+FEC on muicast udp pakcet fix a missed or delayed packet be retranmiitted?

[@privacy312]

amzing seires !!!!!

[@PyNet255]

The built in confirmation system in VOIP is asking the person to repeat what they said :)

[@PracticalNetworking]

Lol, exactly. Layer 8 reliability --- the user ;)

[@Abdirahmaann]

Thanks Ed :) . These days KZbin algorithm is not working well instead of spreading only useless videos :(
