Answer the same question, but this time for the Go-Back-N algorithm as described in section 3.4.3.  Is it possible for a sender using Go-Back-N to receive an ACK for a packet that falls outside its current window?Group of answer choicesIt is NOT possible. The Go-Back-N algorithm is designed to ensure this can not happen.It is possible. The Go-Back-N algorithm is robust enough to handle this situation.

With the selective repeat protocol (as defined in section 3.4.4 of the textbook), it is possible for the sender to receive an ACK for a packet that falls outside of its current window (Textbook page 294, Problem 24)?Group of answer choicesIt is NOT possible. The selective repeat algorithm is designed to ensure this can not happen.It is possible. The selective repeat algorithm is robust enough to handle this situation.

TCP sequence numbers and ACKs (2). Suppose that as shown in the figure below, a TCP sender is sending segments with 100 bytes of payload.  The TCP sender sends five segments with sequence numbers 100, 200, 300, 400, and 500.  Suppose that the segment with sequence number 300 is lost.  The TCP receiver will buffer correctly-received but not-yet-in-order segments for later delivery to the application layer (once missing segments are later received). Complete the sentences below ....After receiving segment 100, the receiver responds with an ACK with value: After receiving segment 200, the receiver responds with an ACK with value: After receiving segment 500, the receiver responds with an ACK with value: After receiving the retransmitted segment 300, the receiver responds with an ACK with value:

c. TCP congestion control example (c). Consider again the figure above (in question 3.7-1a), where a TCP sender sends 8 TCP segments at t = 1, 2, 3, 4, 5, 6, 7, 8 and the segment sent at t=4 is lost, as is the ACK segment sent at t=7.What does the sender do at t=16? You can assume for this question that no timeouts have occurred.Group of answer choicesInform the upper layer that the connection is terminated, and close the socket.Do nothing except increment the number of duplicate ACKs received by 1.Cut its value of cwnd in half, and retransmit the segment with sequence number 300Sets its cwnd window value to 1, and retransmit the segment with sequence number 300

In Go-Back-N ARQ, if 5 is the number of bits for the sequence number, then the maximum size of the send window must be _____.a.15b.1c.31d.16
