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=500 kbps, R2=2 Mbps, and R3=1 Mbps a. Assuming no other traffic in the network, what is the throughput for the file transfer? b. Suppose the file is 4 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 R reduced to 100 kbps.

suppose two hosts, A and B, are separated by 20,000 kilometers and are connected by a direct link of R = 2 Mbps. Suppose the propagation speed over the link is 2.5 x 108 meters/sec. 1. Calculate the bandwidth-delay product, R x dprop. 2. Consider sending a file of 800, 000 bits from Host A to Host B. Suppose the file is sent continuously as one large message. What is the maximum number of bits that will be in the link at any given time? 3. Provide an interpretation of the bandwidth-delay product?
1. Suppose two hosts, A and B, are separated by 30,000 kilometers and are connected by a direct link of R = 3 Mbps. Suppose the propagation speed over the link is 2.5 x 108 meters/sec. a. Calculate the bandwidth-delay product, R _ dprop. b. Consider sending a file of 900,000 bits from Host A to Host B. Suppose the file is sent continuously as one large message. What is the maximum number of bits that will be in the link at any given time?
The network referenced is shown in the picture below: Assume the network uses packet switching and 2 Kilobyte packets. Assume both L1 and L2 each have a propagation delay of 0.1 seconds. We are sending a 100 Kilobyte file. If L1 has infinite bandwidth, and L2 has a bandwidth of 1 Megabit (125 Kilobytes) per second, how long does it take to send the entire file? After the entire file is sent, a single acknowledgment is needed to say the file arrived, how long does the entire process take now (you can assume the ack has negligible size)? If a maximum of 10 packets can be sent per an RTT (this is the equivalent of a fixed window size of 10 packets), how long does it take to send the entire file? What if we start with a congestion window of 1 packet in slow start phase and no slow start threshold, How long to send the entire file now (Hint: This is similar to the previous question but with a variable window rather than fixed)? What if we start in congestion avoidance (linear growth)?
Question 9 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 = 1,024 kbps, R2 = 2,048 kbps, and R3 = 10 Mbps. Assuming no other traffic in the network, how long (in seconds) will it take to transfer a 50 KiB file? Disregard propagation, processing, and queuing delays. Full explain this question and text typing work only We should answer our question within 2 hours takes more time then we will reduce Rating Dont ignore this line
A file of size 20 KiloBytes is transmitted to a destination over a 10 Megabit/s network link (1 Mega = 10^6, 1 Kilo = 10^3, 1 byte = 8 bits). The propagation delay to the destination is 40 milliseconds (1 milli = 10^−3). Assume the queueing delay encountered by packets of the file is negligible. What is the total delay (in milliseconds) for the file to get to its destination?
Let's say Host A wishes to give Host B a sizable file. There are two routers, R1 and R2, and three connections, L1, L2, and L3, on the route from host A to host B. The links' various transmission rates are L1 = 500 kbps, L2 = 2 Mbps, and L3 = 1 Mbps. (Answer the following question while showing work) 1) What is the throughput for the file transfer, if there is no other network activity? 2) Let's say the file has a size of 4 Megabytes. How long will the file transfer from Host A to Host B take?
Calculate total time (in milliseconds) required to send a file of size of 8000 Bytes. Assume RTT (round trip time) of 80 milli second on a link with bandwidth of 0.8 x106bits /second and a packet size of 1000 Bytes where after sending each packet we must wait one RTT before sending the next packet.
Suppose that there are three inter-media nodes between Host 1 and Host 2, and the transmission rate of each link is 4.096 Mbps. The time of end-to-end circuit established is 0.5 second. How much seconds does it take to send a file of 8.192M byte from host H1 to host H2 over a packet-switched network?
