Concept explainers

Network transmission cabling

A network is a collection of devices connected by communication links. A device can be a computer or any instrument capable of sending and receiving data or information formed by other nodes toward the network. A channel that connects people or things is known as a network. It sends the data from one place to another. It is the basic concept of a computer, network, and data communications.

Suppose frames are limited to 1,500 bytes (excluding the 18 bytes of the header and the trailer) between source Host A and destination Host B. What would be the number of frames required to send an MP3 consisting of 1 million bytes (1MB)? Explain how you computed your answer.
Suppose Host A wants to send a large file to Host B. The path from Host A to Host B has three links, of rates R1 = 12.8 Mbps, R2 = 4000 kbps, and R3 = 2 Mbps.a. Assuming no other traffic in the network, what is the throughput for the file transfer?b. Suppose the file is 12 million bytes. Dividing the file size by the throughput, roughly how long will it take to transfer the file to Host B?c. Repeat (a) and (b), but now with R2 reduced to 500 kbps.
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.
2. Host A wants to send a large file to Host B. The Path from Host A to Host B has three sequential link rates, R1 = 200 kbps, R2 = 2Mbps & R3 = 1 Mbps. a. What is the Throughput rate for the file transfer assuming there is no other traffic in the network? b. How long will it take to transfer the file (4 million bytes) to host B? c. c) Repeat (a) and (b) with R2 = 100 kbps?
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)?
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.
