The path from Host A to Host B has three links, of rates R1 = 2 Mbps, R2 = 2 Mbps, and R3 = 4 Mbps. a. Assuming no other traffic in the network, what is the throughput for the file transfer? (5 Points) 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?
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?

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?
Consider a web page whose base file is of size S1 = 10 KB. Assume that the web page consists of N = 20 inline objects each of size S2 = 100 KB. Assume that the round-trip time to the web server is T = 100 ms and the bottleneck capacity is C = 10 Mbps. Ignore any packetization delays and header overhead.a. Assuming non-persistent HTTP is used with a single TCP connection, how long does it take to download the web page?b. Assuming non-persistent HTTP is used with 4 parallel TCP connections, how long does it take to download the web page?c. Assuming pipelined, persistent HTTP is used, how long does it take to download the web page? ”Pipelined” means requests for multiple objects can be sent back-to-back on the same connection.d. Assuming non-pipelined, persistent HTTP with 2 parallel TCP connections is used, how long does it take to download the web page? Assume that the 2 parallel connections equally share the total available bandwidth C.
Calculate the total time required to transfer a 1.5-MB file in the following cases, assuming an RTT of 80 ms, a packet size of 1 KBdata, and an initial 2 RTT handshake before data is sent: The link allows infinitely fast transmit, but limits bandwidth such that only 20 packets can be sent per RTT. The bandwidth is infinite, but during the first RTT we can send one packet, during the second RTT we can send two packets, during the third we can send four, etc.
Pls do fast within 5 minutes and i will give like for sure Solution must be in typed form Question 1 Suppose Host A wants to send a file of size F = 1500 bytes to Host B. The path from Host A to Host B has three links having rates R1 =500 kbps, R2 = 1 kbps, and R3 = 2 Mbps, respectively. Assume there is no other traffic on this network. Assume negligible processing delays. Assume the packets have a size of L = 520 bytes (20 bytes are for header - carry no data from the file - 500 bytes for payload). Assume no other traffic in the network and negligible propagation delay. Answer the following questions: 500bytes = 4.16kb a) What is the end-to-end delay from the time Host A starts transmitting the third packet to the time when the file is completely received at Host B? When answering this question, assume a propagation delay of 100 msec in the first link, 300 msec in the second link, and 200 msec in the third link. Motivate your calculation.
