Hi, I`m sort of new here, and currently working on my bachelor theses. I`ve done lots of searching on various websites, but still confused about terms: Congestion window and Transmission window. Can anybody help on this topic, PLEASE?

Hello Radim.

The transmission window is the amount of data which can be in transit between two endpoints at a given  time. Because of the reliable nature of TCP, a TCP sender can transmit  only a limited amount of data before it must receive an acknowledgement  from the receiver; this is to ensure that any lost segments can be  retransmitted efficiently.

The congestion window is a variable that directly affects the transmission window, this is a value advertise by the send to the TCP peer receiver .

At any given time, the send must not send data when a congestion flag is set in the TCP header.

I hope this helps.

Hi Wilson,

Sorry for late reply, but yes, that helped. By the time I saw yr answer I`ve read some info about it and got a small picture about the windows. As i can see, you`re sort of proffesional in this area. Do you have any experience with Linux? regarding TCP and networking.

I really appreciate your help.

Regards,

Radim H.
