I've been avoiding using "implicit ACK" to describe this, because it's at a different layer.  ACKs deal with packets, but this is really looking at the packet number space.

The parts of this that relate to what to do with those dangling packets from an old packet number space are only really necessary here because we are moving the point where state is discarded earlier.  For other packet number spaces, they are long quiescent by the time any discarding happens, so the advice we'd provide would be largely academic.

You are receiving this because you are subscribed to this thread.
