[tcpm] Re: Discussion on whether the TCP four-wave mechanism can be simplified to three-wave mechanism

["[e-mail]" <[e-mail]>]

Hello I see you later，and I will reply you in 9 PM or before. By the way，Do you have Wechat？（If not, it's okay）I will reply you in the evening of Beijing time, because I am looking for the schematic. Thank you .

Hi Yang,


OK. It seems to me that you're suggesting that when one peer sends the final FIN, it can terminate the connection without waiting for the FIN ACK.
However, if this FIN hasn't arrived at the other end, the other end cannot know the peer has terminated the connection. 
My concern here is that the other end would be suspended in this kind of situation.

Hi Yang,
Are you referring to the 4 way close in TCP? and you want to make it 3 way?

IEFT Hello, I am a Chinese computer major student, I have an idea is to study the TCP four wave mechanism, if one party still has data to pass, continue to open the connection. However, if both parties have no more data to transmit at a given moment, can it be possible to dispense with one wave, thus turning four waves into three? (Go straight back to the finally state at the end of the third time.) For example, is it feasible to go directly to the last step, that is, to change from the original four waves to three waves? Is there a theoretical basis for this assumption and the possibility of practical application?
 
Thank you, looking forward to reply!
 
I wish all the best!
