2 (10 pts) A sender and a receiver are using Go-Back-N

2 (10 pts) A sender and a receiver are using Go-Back-N to perform reliable data delivery. The window size is N = 8. Frames with sequence numbers 1, 2, 3, 4, 5, 6, 7, 8 have been sent and frames 9, 10, 11, 12, 13, 14 are waiting to be sent. The receiver has sent ACKs for frames 1.2.3. 4, but the ACKs have not yet been received. Determine the following: (a) Draw the timing diagram showing this scenario. (b) The sender just received an ACK for frame 1,2. Which frame(s) can the sender transmit before it must wait for the next ACK from the receiver? (c) Assuming ACKs 1,2,3, 4,7,8 are received by the sender, what will the sender do as a result
