Question 2 12.5 pts Numerical answer. In this question we number packets (NOT bytes like in TCP). Suppose that a window based protocol is used with a window size W set to 6. When a receiver gets a packet with sequence number n, it sends back an acknowledgement ack = n + 1 meaning it got packet with sequence number, A sender receives ack number 56. The next sequence number of the packet it will send is Answer 999 if the answer cannot be determined. Question 3 12.5 pts Check all that apply In this question we number packets (NOT bytes like in TCP). Suppose that the Go Back n protocol is used with a window size W, set to 5. When a receiver gets a packet with sequence number 7, it sends back an acknowledgement ack = (n + 1) %W, meaning it got packet with sequence number n (The symbol % stands for Modulo). A sender sends a window with packets numbered 0, 1, 2, 3, and 4. A sender receives ack numbers 1, 2, 4, and 0. The sender will retransmit the packet(s) with sequence number(s) None of these answers 4 D Question 4 12.5 pts Check all that apply In this question we number packets (NOT bytes like in TCP). Suppose that the Go Back n protocol is used with a window size W, set to 4. When a receiver gets a packet with sequence number n, it sends back an acknowledgement ack = (n + 1 %W, meaning it got packet with sequence number n (The symbol % stands for Modulo). A sender sends a window with packets numbered 0, 1, 2, and 3. A sender receives ack numbers 1,2,3, and 0. The sender will retransmit the packet(s) with sequence number(s) None of these answers 4 D Question 5 12.5 pts Numerical answer. In this question we number packets (NOT bytes like in TCP). Suppose that a window based protocol is used with a window size W, set to 6. When a receiver gets a packet with sequence number n, it sends back an acknowledgement ack = n + 1 meaning it got packet with sequence number n. A sender receives ack number 56. The smallest sequence number of the packet it could send is Answer 999 if the answer cannot be determined
