Computer A uses the Go-back-N ARQ protocol to send a 110 Mbytes file to computer B with a window size of 15. Given each frame carries 100K bytes data. How long does it take to send the whole file (the total time taken from A sending the first bit of the file until A receiving the last acknowledgment)? Given that the transmission rate of the link is 500 Mbps and the propagation time between A and B is 15ms. Assume no data or control frame is lost or damaged and ignore the overhead due to header and trailer.
Skype is a well‑known VoIP system used not only for peer‑to‑peer conversations but also for audio and video conferencing involving three or more callers. Assume a video conference with a central server on Skype has N callers, and each caller generates a constant data stream at rate r bps. How many bits per second does the call initiator need to send? How many bits does each of other N‑1 callers need to send?

A frame containing http request is sent from Computer (A) [in whichever subnet it is now, make sure to show it in your figure], to the access point it is associated with. Draw the address fields (1, 2, and 3) of the frame travelling from Computer A to AP and the source and destination addresses of the frame travelling from AP to R1. The MAC addresses of AP1, AP2, and AP3 are M1, M2, and M3 respectively, and the Router R1’s MAC address connected to this Switch/AP is MRA. IP address values are already given, and the port addresses could also be used as given. The Router’s MAC address facing WAN side is MRW.
For NAT Network Address Translation Scenario: Jenny Bello is a small business owner selling and making customized computer peripherals. She has been finding it difficult to track her sales and inventories, however recently after an expert's advice, she adopted a Point of Sale (PoS) server. So, she can now track her sales and inventories at the store. However, she ran into another issue, the server can only be accessed within the store, because it has been assigned a private IPv4 address, it is not publicly accessible via the Internet. a) Why is not having the PoS server accessible over the Internet a problem for the business? b) What caused this problem? c) Propose a solution for the problem and explain how the solution works.
We compress the video with the pattern GoP (16 : 3) by using MPEG coding. Assume that the average compression ratios of frame I, frame P, and frame B are 1:5, 1:20, and 1:60, respectively. We put the compressed frames in 512 B packets and send them. The header size of each packet is 5% of the size of packet. Each packet contains information on one frame and its header, Each frame can be sent in multiple packets. Picture resolution is 196 × 144 for a video at 32 fps. (a)What is the compression ratio in this pattern? (b)What is the order of coding and transmitting frames in this pattern? (c)If frame 6 is lost while transmission, which frames will be faulty?

Write a program to simulate the behavior of the CSMA/CD protocol over Ethernet when ther are N stations ready to transmit while a frame is being transmitted. Your program should report the times when each station successfully starts sending its frame. Assume that a clock tick occurs every slot time (51.2 microsec) and a collison detection and sending of a jamming sequence takes one slot time. All frames are the maximum length allowed.
(a) Suppose a server S and client C are connected over the Internet. The one-way prop- agation delay from S to C is 50 ms. The maximum throughput between S and C is R = 200 Mbps. A browser on client C makes an HTTP request for a webpage on server S. The base HTML file is of size 500 KB and it references five objects, each of size 5 MB. Find the total response time for the client to receive the entire webpage using nonpersistent HTTP with up to two parallel connections. Assume that when two par- allel connections are active, the throughput for each connection is 40% of the maximum throughput R. (b) Suppose an application running on host ece.gmu.edu needs to resolve the domain name cs.vtech.edu. Draw a diagram (with labels) showing the sequence of queries/responses in a recursive DNS query to find the answer in a scenario where all levels of the DNS hierarchy are involved.
Suppose Alice and Bob are going to communicate using AES in CBC mode. Unfortunately Alice's message length (in bytes) is not a multiple of 16. Suppose the last block of her message is just a single zero byte. How can she pad out the last block so that she can use CBC mode? Since this needs to be a reversible operation, how does Bob recognize the padding and remove it?
Suppose that a binary message – either 0 or 1 – must be transmitted by wire from location Ato location B. However, the data sent over the wire are subject to a channel noise disturbance,so to reduce the possibility of error, the value 2 is sent over the wire when the message is1, and the value −2 is sent when the message is 0. If X, X = {−2,2}, is the value sent atlocation A, the value received at location B, denoted as R, is given byR = X + N ,where N is the channel noise disturbance, which is independent of X. When the message isreceived at location B, the receiver decodes it according to the following rule:if R ≥.5, then conclude that message 1 was sentif R < .5, then conclude that message 0 was sentAssuming that the channel noise, N, is a unit normal random variable and that the message0 or 1 is sent with equal probability, what is the probability that we conclude that the wrongmessage was sent? This is the probability of error for this communication channel
When we encode a signal (a stream of bits) in the physical layer, we convert the bits into different voltage levels. We have a choice of the signal level range, and how many different levels to use, but all communicating nodes must agree on the encoding scheme so that they may properly decode the signal later. For example, we might encode values as either 0 volts (OV) or 5 volts (5V), therefore using two signal levels. We might encode 0V, 10V, 20V, 30V, 40V, 50V and have six signal levels. There is no "correct" choice of encoding scheme for all situations. a) How would the distance of a link affect this decision? (The physical distance between two communicating machines which are using the same encoding scheme) b) In what way might cost be an issue when deciding the scheme?

NRZ-Iusing each of the given data streams, assuming that the last signal level has been positive. From thegraphs, guess the bandwidth for this scheme using the average number of changes in the signal level.
