Consider a sender having an infinite number of frames to send, which we index as 0, 1, 2, ..... Assume the transmission delay of each frame is 3t, the ACK transmission time is 1t, the propagation delay is 2t and symmetric on both directions, and the timeout value is T = 10t starting from the end of frame transmission onto the link. The first frame is sent out at time 0. 

QUESTION 1:   Draw the timing diagram of Stop-and-Wait Protocol (SWP) with 3 frames (numbered 0-2) being sent and acknowledged, where frame #1 (the second frame) is lost. List the sequence number of each frame at the sender side, and explicitly indicate the timeout in the diagram. (Note: Include both sender and receiver timelines in parallel on the timing diagram). 

QUESTION 2:  In the above SWP operations, what is the time when ACK of frame #1 is received? What is the efficiency of the SWP operation from the beginning to the end of transmission?
