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
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.
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?
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
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 ?

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!
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
Your explanations are so simple and understandable! Thank you
Studying for college class right now. in 1 min 50 sec. you explained clearly how this works. Thank you
The best explanation of the tree-way handshake!!!
Superb explanation, especially with the details of the Ack# and Seq# and you useful examples. Thank you. (FYI - details begin at 2:00)
I'm studying for my exam and THIS IS AMAZING! Thank you so much :)
Thanks sir for the short n sweet tutorial. Loved it.
My pleasure
needed a quick understanding about the TCP handshake. I ll recommend this video to my friends. Loved it!!
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.!
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!
This video is pure gold. Thank you so much.
Glad it was helpful!
very good, very clever. Now I know the process of three tcp-handshake.
Thank you for your time!
Way of explaining is outstanding sir,thank you sir
simply but effectively explained. thank you sir.
you are welcome!
Санни, храни тебя Господь!

very clear
thanks.
thank you sunny!
Thanks for information
Thx you save my test
Excellent explanation :D
Thank you sunny!! :)
You're welcome 😊
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.
Nice explanation, Have a ques here from Packet 1 to Packet 3 what are the SYN bit & ACK bit! Thanks

Thanks a lot.
Thanks, appreciate every detail
thank you this video help me a lot
I fucking love the music at the end.
Amazing and clear explanation. Thank you so much!

Thank you
You're welcome
Great thank you sir!
Question: What happens if the server was decline the request connection from the client?
Thank you.😊
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
thank you Sir
fantastic
Thanks!
Awesome :D
Thanks a lot!
good1. Thanku!
Is this a two way or three way connection
I have a question, The protocol TCP must send a conection each time that send a frame????
Please explain on handshake based communication hardware and softly handshake
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 ?
