📺🧩 TCP Masterclass: kzread.info/head/PLIFyRwBY_4bS-PQZoF0UySdG0sH9VA0bn 🚨📢 Announcement: *I'm creating a full Networking course!* Details --> pracnet.net/networking 👉👉 Enroll now for *discounted early access* to the course and a chance to help shape its content. 📺🕸 Module 1 of the course is *free* : kzread.info/head/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: kzread.info/head/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. =)

how is the Network course coming along ?

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

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 KZread is lol. Keep making these videos, they are amazing!

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.

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 😆

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

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

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

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

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. 💯💥

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

Loved that voip packet loss demonstration lol

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

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

You are the best teacher. Thank you

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 !

Crystal clear explanation, thank you!

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

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.

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

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

Very informative video.

Yaay ! a new introduction =)

The content is awesome! Thanks

Awesome Video!

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❤🙏

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.

thanks for the excellent video !

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

Great work! Stay blessed

Thanks. I've a better understanding.

Thank you very much!

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

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.

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 =)

honestly, i just wanna TIP you. awesome job

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.

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

Very nivet video.

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

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

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

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

Hi eddie, just wanted to let you know that i got selected as an SRE intern, Thanks to your videos. You're an inspiration. also i'm looking to buy the networking course on your site. when do the videos start rolling out? hope you reply. Thanks again!!

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

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

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

Web 3.0 use Quic which is based on udp :)

great

Ed is awesome

Great Information, Thanks for sharing!

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

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

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

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

❤️👍

I pray that the world knows your worth cos you're worthy.

Can I collab with you to create the contents in Hindi for larger audience? 1 billion people in India now have access to internet/ KZread.
