consider sending a large file from one host to another over a tcp connection with no loss. suppose tcp uses aimd for its congestion control without the slow start mode. the initial congestion window (cwnd) is 5 mss and increases by 1 mss after each transmission round. assume that the round-trip times (rtts) average 1 second with negligible deviation. what is the average throughout (in mss/rtt) for this connection up through the 8th transmission round from the start if there were no duplicate acks or packet losses?
