Hi,

Jacobson tells to halve the congestion window in response to the congestion, in his "Congestion avoidance and control" paper.

"On any timeout, set cwnd to half the current window size"

However, in tcp.cc the congestion window is only halved in response to an ECN event.

And Jacobson also tells to set the cwnd to 1 after any restart for any loss.

Can anyone clarrify when a timeout occurs and when (and how) a loss is detected?

cheers,
