Suppose a TCP connection has a window size of 8 segments and an RTT of 800ms. The sender sends segments at a constant rate of one every 100ms, and the receiver sends ACKs back at the same rate without delay. A segment is lost, and the fast retransmit algorithm on the receipt of the third duplicate ACK detects the loss. At the point when the ACK of the retransmitted segment finally arrives, how much total time has the sender lost (compared to lossless transmission) if the sender waits for the AC
