Once a loss happens, it's too late to stop doing the stretch ACKs, the damage is done already. It is going to take you at least one extra RTT to recover from the loss compared to if you were not doing stretch ACKs. You have to keep giving consistent well spaced ACKs back to the receiver in order to recover from loss optimally. The ACK every 2 full sized frames behavior of TCP is absolutely essential. _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
