Q4. [CO3] Answer the following questions related to the FSM's for the Selective-Repeat protocol with m = 7 bits (Assuming different time is used for each packet: [3 Marks] a. The sending machine is in the ready state with Sf = 10 and Sn = 15. The timer for packet 10 times out. How many packets are to be resent? What are their sequence numbers? b. The sending machine is in the ready state with Sf = 10 and Sn = 15. An ACK with ackNo = 13 arrives. What are the next values of Sf and Sn? What is the action in response to this event? C. The sending machine is in the blocking state with Sf = 14 and Sn = 21. An ACK with ackNo = 14 arrives. Packets 15 and 16 have been already acknowledged. What are the next values of Sf and Sn? What is the state of the sending machine?
