Consider an Infrastructure BSS with an Access Point and two Mobile Stations, and let’s use AP, M1, and M2 to denote their MAC addresses. Both M1 and M2 are associated with the AP. Suppose M1 wants to send a data frame to M2. When this data frame is relayed by the AP, explain how the AP shall update the four address fields of the data frame.
Two hosts are connected by a single direct link. Link transfer the data at a rate of 107 bits/seconds. The distance between the two host is 5000 km and the propagation speed along the link is 2 x 105 kilometer per second. One host is sending a data of 10,000 bytes in a single packet to another host. Let T₁ be the transmission delay and Tp be the propagation delay. The difference between the propagation delay and the transmission delay in millisecond is

Calculate the end to end delay between Host A and Host B, when the propagation speed at each link is approximately 2x108 m/sec, and the processing and queuing delays at the router are 10 msec and 25 msec, respectively, when: (a) File size is 1500 bytes and only one packet is sent. 4 (b) File size is 6000 bytes and four packets are sent (1500 bytes in each packet).

Use again the network architecture provided in the figure above, were Rs, Rc and Ri for i = {1,2,3,4}, the transmission rates of the server link, client link and intermediate network links. Consider a message that is 60 · 106 bits long that is to be sent from client to server. Ignore propagation, queuing, and processing delays. c.How long does it take to move the file from source host to destination host when message segmentation is used and both path R1, R2 and path R3, R4 are used? How many packages should be routed from path R1, R2 and how many from path R3, R4 in order to maximize the use of the network? d.What is the end to end throughput if path R1, R2 is used, and what if path R3, R4 is used? What is the total throughput from client to server (if both paths are being used at the same time)?

Suppose two hosts (Host-A and Host-B) are connected through a shared Ethernet bus of 1 Mbps. The distance between two nodes is 5 meters. The signal propagation speed over physical media is 2.5 x 10^5 meters/second. Compute the propagation delay in this case. What will be the propagation delay for a shared bus of 10 Mbps instead Suppose both hosts sense idle channel at the same time and starts transmission. Will it result in collision (yes or no) If yes: How much time is needed to detect this collision at Host-A? If yes: How much time is needed to detect this collision at Host-B?

Delays. A user in Madagascar, connected to the internet via a 100 Mb/s (b=bits) connection retrieves a 250 KB (B=bytes) web page from a server in Tokyo, where the page references three images of 500 KB each. Assume that the one-way propagation delay is 82 ms and that the user’s access link is the bandwidth bottleneck for this connection. a.) Approximately how long does it take for the page (including images) to appear on the user’s screen, assuming non-persistent HTTP using a single connection at a time? (For this part, you should ignore queueing delay and transmission delays at other links in the network)b.) Assume a cache rate of 45% on the information received by the user in Madagascar from the Tokyo server. How does this affect your answer in a? Show your work.
