The equation for determining the download time for a peer-to-peer file sharing and client/server file sharing is given below. i) F/us ii) F/dmin NF U s Match the following terms to what they represent iii) iv) Us + NF Us Dp2p max(F/us, F/dmin, NF N vi=1 Ui Des NF us + qui max( F dmin 1) Time needed for server to upload one copy of the file 2) Time for cooperating peers + server to upload a copy of the file to all peers 3) Time for server to upload file to all clients 4) Time for slowest peer to download one copy of the file (b) True or False: assuming that the server participates in the peer to peer exchange (as in the equation above), peer to peer download will always be faster than or the same speed as client/server download. Explain your answer (c) You are building a communication network based on RFC 1149 "IP over avian carrier". You attach two 128GB flash drives to your pigeon. You can write data to the flash drive at the rate of 20 MB/s and you can read data from the flash drive at the rate of 50MB/s. The flying speed of a pigeon is 80km/h and pigeons do not need to stop for food or rest before reaching destination. i. What is the total time needed for you to send and your friend who lives in Brazil (Rio is 13600 km from Adelaide) to receive a 4 * 10 bit file of your favourite home movies? Solve for the number of seconds delay. Show your work. ii. Under what conditions would IP over avian carrier have a lower propagation delay or transmission delay than using the Internet? Explain your answer. (d) Give two reasons why iterative DNS queries are preferred to recursive DNS queries. Explain your answer.
