Cоnsider the figure belоw in which а TCP sender аnd receiver cоmmunicаte over a connection in which the segments can be lost. The TCP sender wants to send a total of 10 segments to the receiver and sends an initial window of 5 segments at t = 1, 2, 3, 4, and 5, respectively. Suppose the initial value of the sequence number is 15 and every segment sent to the receiver each contains 819 bytes. The delay between the sender and receiver is 7 time units, and so the first segment arrives at the receiver at t = 8, and an ACK for this segment arrives at t = 15. As shown in the figure, 1 of the 5 segments is lost between the sender and the receiver, but one of the ACKs is lost. Assume there are no timeouts and any out of order segments received are thrown out. Answer the following questions, making sure to include only numbers or the letter 'x' in your answer. What is the sequence number of the segment sent at t=1? [q1] What is the sequence number of the segment sent at t=2? [q2] What is the sequence number of the segment sent at t=3? [q3] What is the sequence number of the segment sent at t=4? [q4] What is the sequence number of the segment sent at t=5? [q5] What is the value of the ACK sent at t=8? (If segment lost, write 'x') [q6] What is the value of the ACK sent at t=9? (If segment lost, write 'x') [q7] What is the value of the ACK sent at t=10? (If segment lost, write 'x') [q8] What is the value of the ACK sent at t=11? (If segment lost, write 'x') [q9] What is the value of the ACK sent at t=12? (If segment lost, write 'x') [q10] What is the sequence number of the segment sent at t = 15? (If ACK never arrives, write 'x') [q11] What is the sequence number of the segment sent at t = 16? (If ACK never arrives, write 'x') [q12] What is the sequence number of the segment sent at t = 17? (If ACK never arrives, write 'x') [q13] What is the sequence number of the segment sent at t = 18? (If ACK never arrives, write 'x') [q14] What is the sequence number of the segment sent at t = 19? (If ACK never arrives, write 'x') [q15]
Cоnsider the figure belоw in which а TCP sender аnd receiver cоmmunicаte over a connection in which the sender->receiver segments may be lost. The TCP sender sends an initial window of 4 segments. Suppose the initial value of the sender->receiver sequence number is 402 and the first 4 segments each contain 301 bytes. The delay between the sender and receiver is 7 time units, and so the first segment arrives at the receiver at t=8. As shown in the figure below, 2 of the 4 segment(s) are lost between the segment and receiver. What is the sequence number of the segment sent at t=1? [q1] What is the sequence number of the segment sent at t=2? [q2] What is the sequence number of the segment sent at t=3? [q3] What is the sequence number of the segment sent at t=4? [q4] What is the value of the first ACK sent by the receiver? (If segment lost, write 'x') [q5] What is the value of the second ACK sent by the receiver? (If segment lost, write 'x') [q6] What is the value of the third ACK sent by the receiver? (If segment lost, write 'x') [q7] What is the value of the fourth ACK sent by the receiver? (If segment lost, write 'x') [q8]
