Hi,

I have a Client-Router-Server (tcpsack) model.

Which is the cause that no packets are transmitted and the REXMIT Timer expired?.

Just guessing from the figure. If the window is 0, the sender does zero window probing,
which means after a timeout it sends a byte, but thats it. The sender can't send more
due to flow control.

Ok. I'm just studying congestion control. How I can disable flow control (AdvertisedWindow)?.

You can't disable it. But you can set the advertised receiver window to a large
value such that flow control does not kick in.

Best regards
