31. Draw a timeline diagram for the sliding window algorithm with SWS = RWS = 3 frames, for the following two situations. Use a timeout interval of about 2 × RTT. (a) Frame 4 is lost. (b) Frames 4 to 6 are lost. Hints/Help: Look at extra problem #32 for a timeline example. In this problem, assume that it takes ¼ RTT to transmit a frame. Use a timeout of 2 RTT. a) When frames 5 and 6 are received no ack is sent. An ack is sent for frames 4,5 and 6 once the retransmitted frame 4 is received. Something to keep in mind (but not part of this problem) is when a frame is received (but not 4), protocol could have the receiver send an ack for frame 3 again which indicates a frame received but not 4. b) When frames 4-6 are sent, the transmitter needs to wait for an ack or for timeout before sending another frame.
