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.
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
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 ...
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 ?
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?
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
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 ?
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.
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.
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
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
Your explanation of the TCP -handshake is perfect. I really appreciate the little extra details about the Ack# and Seq#.
Thank you very much.
The appreciation is from my side as well
Studying for college class right now. in 1 min 50 sec. you explained clearly how this works. Thank you
I went back to your channel. Just to thank you. It really helped alot specially for my report. Thanks man!
You are welcome!
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.

Thank you, Sunny, the best explanation ever! Very simple and clear!
Thank you for your encouragement!
What a Legend i Spent All Day Trying To Understand And He Explained it in 4 mins
Superb explanation, especially with the details of the Ack# and Seq# and you useful examples. Thank you. (FYI - details begin at 2:00)
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
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 ...
The best explanation of the tree-way handshake!!!
I'm studying for my exam and THIS IS AMAZING! Thank you so much :)
Your explanations are so simple and understandable! Thank you
Way of explaining is outstanding sir,thank you sir
needed a quick understanding about the TCP handshake. I ll recommend this video to my friends. Loved it!!
Thnxxx a lot Sr
U r great Sr.. I understand it easily..
Tomorrow is my paper
Plzz do pray fr me...
I will. Thank you for your time!
Nice explanation with incrementing sequence numbers. Simple basic explanation!
Thanks sir for the short n sweet tutorial. Loved it.
My pleasure
simply but effectively explained. thank you sir.
you are welcome!
very good, very clever. Now I know the process of three tcp-handshake.
Thank you for your time!
Love how AI has advanced so much that they have youtube lectures for us now ^^
Thank you very much for your praise. I also have feelings : )
@@sunnyclassroom24 I respect your feelings.!

awesome !!! thanks for doing this video. thanks for going into technical details :) I also love the way you explained subnetting :)
Great sir best contend to understand TCP connection
Short and to the point tutorial. Amazing
Big Thanks :)
Thank you, Sunny. Great explanation!
Your videos are so neat clean and best in world
I love UA-cam because of you and like you
Thanks a lot for saying so!
Great explanation. Thank you very much Sunny !!!
Nice explanation, Have a ques here from Packet 1 to Packet 3 what are the SYN bit & ACK bit! Thanks
Thank you sir, I understood much better now❤️👍
Санни, храни тебя Господь!
Great explanation, keep it up!
Amazing and clear presentation
Sunny rocks!, great and easy to understand videos.
Thanks a lot!
wow that was soo clear and easy to understand
this is great sunny! thanks a lot
My pleasure!
Explained very well, thankyou 🌟
thank you Sunny, very clear!
Great vid, thanks for the elaborate explanation.
thanks a lot.
Thank you very much for the clear video!
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?
two-way conversation. You need to wait for reply.
very good explanation
crisp and clear!
This was very helpful! thank you so much !!
You are welcome!
Thank you for such a helpful explanation!
Perfect exactly what i needed!
Very enjoyable and educational, thanks a lot, Teacher :)
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 :-)
Finaly I got this 😂 thanks a lot 👍
Question: What happens if the server was decline the request connection from the client?
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 ?

Why?
Is there anything I'm misunderstanding or you made a mistake?
great explaination!
Thanks a lot sir i was a good explaination
Please explain on handshake based communication hardware and softly handshake
again perfect, thanks sir
great explanation, thank you
You are welcome!
Excellent explanation :D
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
Is this a two way or three way connection
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 ?
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.
is there a timer used for start with the client which counting times for the request to the server and reply from the server.
Yes, that is call tcp connection initial timeout, that may be different according to each vendor, application or device
Very good teacher!
Thanks a lot.

SYN-ACK SYN message from local device and ACK of the earlier packet.
I have a question, The protocol TCP must send a conection each time that send a frame????
You are the man !!!!
shouldn't there be an ACKbit?
what the diffence between web session and three way handshake
thank you this video help me a lot
Amazing and clear explanation. Thank you so much!
You are welcome!
It really does help
I am happy it is helpful!
Thank you sunny!! :)
You're welcome 😊
Brill just Brill thank you sir
Thanks, appreciate every detail
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
Thx you save my test
very clear
thanks.
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
thank you sunny!
Thanks for information
Thank you so much!!!!!
You are welcome!
I fucking love the music at the end.
Great thank you sir!
very good
Thanks.
