Once you open this exam, you will have 2.5 hours to complete it. You are permitted to use your calculator only. You must clearly show all necessary work, and when using your calculator, indicate what functions or values were used. Be specific about the type of interval (e.g., proportion, t-interval, z-interval) and the type of test (e.g., t-test, z-test, proportion test) used for any hypothesis testing. Upload your completed work in the assignment submission area located directly below the test link, at the end of the exam or in the exam itself where you can. If you are uploading to the assignment link you have 30 minutes after completion of the exam to do this. Work uploaded after this time will not be accepted.You are not to use the binomial formula. Please use the calculator for these questions and state the n, p and x that you usedThis exam must be completed independently. Do not access the internet or seek assistance from others. All work should reflect the methods taught in class and practiced in assignments. You are not permitted to use a z-table or t-table—any use of them will result in no credit for those problems.Any form of academic dishonesty, including unauthorized assistance or materials, will result in a score of zero on this exam.

Consider the figure below, in which a TCP sender (Host A) sends 8 TCP segments at t = 1, 2, 3, 4, 5, 6, 7, and 8. Suppose the initial value of the sequence number is 0, and every segment sent to the receiver (Host B) contains 40 bytes. The delay between the sender and receiver is 5 time units, and so the first segment arrives at the receiver at t = 6. The ACKs sent by the receiver at t = 6, 7, 8, 10, 11, 12, 13, 14 are shown. The TCP segments (if any) sent by the sender at t = 11, 13, 15, 16, 17, 18 are not shown. The segment sent at t=6 is lost, as is the ACK segment sent at t=7 and t=8.                   If it is a Go-Back-N a.   (5 pts) When ACK at t=14 is received, will Host A send out any packets? Yes or No? ________If yes, how many packets will be sent, and what will their sequence numbers be? Number of packets: ________   Sequence numbers: ________  If No, why not?   b.   (5 pts) When at the timeout point, how many packets will be sent by Host A, and what will their sequence numbers be? Number of packets: ________ Sequence numbers: ________     If it is a Selective Repeat c.   (4 pts) When ACK at t=17 is received, will Host A send out any packets? Yes or No? ________ If yes, how many packets will be sent, and what will their sequence numbers be? Number of packets: ________ Sequence numbers: ________ If No, why not?   d.   (4 pts) When at the timeout point, how many packets will be sent by Host A, and what will their sequence numbers be? Number of packets: ________ Sequence numbers: ________
