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 ...
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.
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
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 :-)
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.
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?
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 ?
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
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 ?

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
I went back to your channel. Just to thank you. It really helped alot specially for my report. Thanks man!
You are welcome!
Studying for college class right now. in 1 min 50 sec. you explained clearly how this works. Thank you
Thank you, Sunny, the best explanation ever! Very simple and clear!
Thank you for your encouragement!

You are welcome! Thank you for your time! Check out my other videos please!
What a Legend i Spent All Day Trying To Understand And He Explained it in 4 mins
The best explanation of the tree-way handshake!!!
Way of explaining is outstanding sir,thank you sir

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 ...
Your lectures are really helpful sir, thank you
Nice explanation with incrementing sequence numbers. Simple basic explanation!
Superb explanation, especially with the details of the Ack# and Seq# and you useful examples. Thank you. (FYI - details begin at 2:00)
Your explanations are so simple and understandable! Thank you
I'm studying for my exam and THIS IS AMAZING! Thank you so much :)
Thanks sir for the short n sweet tutorial. 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!
very good, very clever. Now I know the process of three tcp-handshake.
Thank you for your time!
It is a very success of you, that i could easily understand
I want to give you a handshake for this explanation, well done.
simply but effectively explained. thank you sir.
you are welcome!
needed a quick understanding about the TCP handshake. I ll recommend this video to my friends. Loved it!!
This video is pure gold. Thank you so much.
Glad it was helpful!
Very well explained... I find your videos very useful.
Thank you very much for watching them and make comments.
you are the best teacher!!!!!!

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.!
Great sir best contend to understand TCP connection
This video is amazing.
Pure gold content!
Thank You Sir :)
Amazing and clear presentation
awesome !!! thanks for doing this video. thanks for going into technical details :) I also love the way you explained subnetting :)
I love TH-cam because of you and like you

great explaination!
Thanks a lot sir i was a good explaination
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
Nice explanation, Have a ques here from Packet 1 to Packet 3 what are the SYN bit & ACK bit! Thanks
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 :-)
again perfect, thanks sir
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 explanation, thank you
You are welcome!
Excellent explanation :D
Finaly I got this 😂 thanks a lot 👍
Very good teacher!
Thanks a lot.
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.
Amazing and clear explanation. Thank you so much!
You are welcome!
very clear
thanks.
Brill just Brill thank you sir
It really does help
I am happy it is helpful!
thank you this video help me a lot
Please explain on handshake based communication hardware and softly handshake
Thank you sunny!! :)
You're welcome 😊

Why?
Is there anything I'm misunderstanding or you made a mistake?
thank you sunny!
Thanks, appreciate every detail
very good
Thanks.
Thx you save my test
I fucking love the music at the end.
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 ?
Thanks for information
Question: What happens if the server was decline the request connection from the client?
Thank you so much!!!!!
You are welcome!
Awesome
Thank you for watching!
Thank you
You're welcome
fantastic
Thanks!
Great thank you sir!
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
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
beautiful
Thank you.😊
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
Awesome :D
Thanks a lot!
I have a question, The protocol TCP must send a conection each time that send a frame????
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 ?
