TCP - Three-way handshake in details 

Your explanation of the TCP -handshake is perfect. I really appreciate the little extra details about the Ack# and Seq#.

I went back to your channel. Just to thank you. It really helped alot specially for my report. Thanks man!

Hey sunny! Just wanted to say that thanks to your videos I was able to quickly learn about TCP and networking in general and pass a job interview! Thank you so much.

The best explanation of the tree-way handshake!!!

Thank you, Sunny, the best explanation ever! Very simple and clear!

Sunny, Thank you, I have never had the 3 Way Handshake explained so accurately and clearly and come away with such simple clarity. Thank you once again. JB

What a Legend i Spent All Day Trying To Understand And He Explained it in 4 mins

Thank you. This is the only video thst is extremely clear. For example network direction explanation was confusing..... Didn't even have an ack number lol. Was awful. Yours is crystal clear. Thank you ...

Studying for college class right now. in 1 min 50 sec. you explained clearly how this works. Thank you

Way of explaining is outstanding sir,thank you sir

Nice explanation with incrementing sequence numbers. Simple basic explanation!

Your explanations are so simple and understandable! Thank you

I'm studying for my exam and THIS IS AMAZING! Thank you so much :)

very good, very clever. Now I know the process of three tcp-handshake.

Superb explanation, especially with the details of the Ack# and Seq# and you useful examples. Thank you. (FYI - details begin at 2:00)

Thanks sir for the short n sweet tutorial. Loved it.

I want to give you a handshake for this explanation, well done.

This video is pure gold. Thank you so much.

Thnxxx a lot Sr U r great Sr.. I understand it easily.. Tomorrow is my paper Plzz do pray fr me...

It is a very success of you, that i could easily understand

needed a quick understanding about the TCP handshake. I ll recommend this video to my friends. Loved it!!

simply but effectively explained. thank you sir.

Love how AI has advanced so much that they have youtube lectures for us now ^^

Easy to understand thank you sir from india....

man your teaching is awesome, Thnx!

Very good explanation, helped clear up some confusions I had! :)

Very well explained... I find your videos very useful.

you are the best teacher!!!!!!

Your videos are so neat clean and best in world

perfect explanation of the topic. really helped me unterstand especially due to the presentation. thanks

Great sir best contend to understand TCP connection

Amazing explanation sir ✔

Sir, your videos are extremely useful !! Thanks a lot !!

wow that was soo clear and easy to understand

Санни, храни тебя Господь!

I love RU-vid because of you and like you

Thank you, Sunny. Great explanation!

Nice explanation, Have a ques here from Packet 1 to Packet 3 what are the SYN bit & ACK bit! Thanks

Amazing and clear presentation

Thank you very much for the clear video!

Great vid, thanks for the elaborate explanation.

Great explanation. Thank you very much Sunny !!!

Sunny rocks!, great and easy to understand videos.

Thank you for such a helpful explanation!

awesome !!! thanks for doing this video. thanks for going into technical details :) I also love the way you explained subnetting :)

This video is amazing. Pure gold content! Thank You Sir :)

Great explanation, keep it up!

Explained very well, thankyou 🌟

thank you Sunny, very clear!

Thank you sir, I understood much better now❤️👍

Perfect exactly what i needed!

this is great sunny! thanks a lot

very good explanation

Short and to the point tutorial. Amazing Big Thanks :)

This was very helpful! thank you so much !!

So can you have a one way connection if the PC doesn't acknowledge the server's SYN or will the connection be discarded altogether?

Thanks a lot sir i was a good explaination

crisp and clear!

Hi, in the 3rd step client only sends the ACK number# to the server. No sequence number number is sent to it. As sequence number is for connection request and ACK is for confirmation. No reuest is made at the 3rd step but the confirmation. But you have shown 9002( supposed ) as a SEQ sent to the Server! Why? Is there anything I'm misunderstanding or you made a mistake?

great explanation, thank you

Very enjoyable and educational, thanks a lot, Teacher :)

Amazing and clear explanation. Thank you so much!

At 2.36 time, the SYN_ACK packet also has ACK flag set to 1 along with SYN flag. and Ack sequence number + own sequence number. Same for third step in ACK.

great explaination!

thank you this video help me a lot

Hi, this video is also put in "3 Ethernet Basic", I suspect it is an error. I highlight this only because I am using your playlists with my class, thanks for the good videos :-)

sir ye tho agar two way hua jo ki aap lekh rahai ho tho three ways kya alag hai , aur dodno main kya difference hai two way and three way handshake main ?

again perfect, thanks sir

Is this a two way or three way connection

You are the man !!!!

Please explain on handshake based communication hardware and softly handshake

thank you sunny!

Question: What happens if the server was decline the request connection from the client?

Excellent explanation :D

Finaly I got this 😂 thanks a lot 👍

Very good teacher!

theres 1 thing wrong. According to book data communication and networking by forouzan acknoledegement doesnt consume sequence number so both syn andd ack segment will have same sequence number

Thanks for information

shouldn't there be an ACKbit?

Thx you save my test

Thank you sunny!! :)

I have a question, The protocol TCP must send a conection each time that send a frame????

Brill just Brill thank you sir

what the diffence between web session and three way handshake

Thanks, appreciate every detail

TCP - a connection oriented protocol - 3 way handshake is required before data segment transmission to establish a connection - client sends a syn segment requesting for synchronization, connection - server replies with a syn ack segment, where it first acknowledges the client's request with the ack and secondly also asks the client for to open connection - allow - the client then finally responds with an ack, an acknowledgement which is like a yes/agreement ServerAck = ClientSyn + 1 ClientAck = ServerSyn + 1

It looks like you use camel case name for sequence number, all uppercase name for the flag. If you add ACK flag, it will be much clear, so first message ACK# is 0, second ACK# is 1, third ACK# is 1

It really does help

very clear

hey broh, when i capture and see my tcp packets, there is tcp options, and the numbers in tcp options is different from the previous packet, what is that and what make the number increment ?

I fucking love the music at the end.

is there a timer used for start with the client which counting times for the request to the server and reply from the server.

Three-Way HandShake or a TCP 3-way handshake is a process that is used in a TCP/IP network to make a connection between the server and client. It is a three-step process that requires both the client and server to exchange synchronization and acknowledgment packets before the real data communication process starts. Message Description Syn Used to initiate and establish a connection. ACK Helps to confirm to the other side that it has received the SYN. SYN-ACK SYN message from local device and ACK of the earlier packet.

Thank you

Great thank you sir!

thank you Sir

Thank you so much!!!!!

Thank you.😊

beautiful

very good
