I read a lot blogs about tcp protocol. They all mention the congestion avoidance that once the timeout occured, tcp will set the ssthresh half as before. But none of them refer to how to increase the ssthresh. I'm curious about it when/how to increase ssthresh.
I have an assumption that every tcp connection has its own ssthresh, and there is a default value of the ssthresh, which every tcp connection'ssthresh increses from. I don't know if I'm right, or if there is any other mechanism?
